Rating of the best liquids for removing ice from car windows in 2022

In cold weather, car windows are often covered with a crust of ice, sometimes very thick. Removing it with a scraper takes a very long time and there is a possibility of scratching the surface if the icing is too strong. For this purpose, there is a special chemistry that allows you to quickly melt the ice. In this regard, we present to you the rating of the best car window defrosters for 2022. It includes the most effective products from domestic and foreign manufacturers in different price categories.

3ton

The 3ton glass defroster is perfect even for severe frosts. It does not lose its properties even at very low air temperatures. The product is quick and easy to apply. It does not leave marks and does not damage the paintwork if it accidentally gets on it. For the composition to take effect, usually only five minutes or a little less is enough. It perfectly removes thin ice crust. Thicker ice will have to be removed with a scraper. But doing this will be much easier and faster than without processing. To defrost, only a small amount of the drug is needed. Therefore, it lasts for a long time. And it costs about 100 rubles.

miniatura799–1

When rain and frost come together in a duel, the losers are usually the car windows. Even if you get into an icy car and start the engine, you will not be able to leave: there is no visibility. Having the windshield wipers pulled up in advance won't do any good - you'll only damage the rubber bands. It’s a little easier for owners of cars with a heated windshield, but electricity won’t help instantly either. In general, you will have to grab a scraper or... That’s what we’ll talk about “or”.

Hi-Gear Windshield De-Icer

Hi-Gear Windshield De-Icer fluid is quite expensive for this type of automotive chemical. But its effectiveness is incredibly high. It helps remove even heavy frost in just a few minutes.

The overseas can generally passed the test, although it required vigorous shaking. But using an aerosol is inconvenient, especially at -30 ºС. The icy metal tends to burn your hand with cold, and the trickle of the drug is modest.

BBF

Anti-ice for glass BBF has a very simple composition and a relatively low affordable cost. At the same time, its efficiency is quite high. The product quickly removes snow and ice. It can be used not only on glass, but also on side mirrors and lighting devices. It is safe, does not damage paintwork and does not leave any streaks or marks on the surface. Processing time is only a few minutes. The composition is economical; very little of it is required to remove even heavy icing. It costs about 200 rubles.

Method No2

An option for those who can get somewhere on their own and leave the car for a while, going to solve their personal affairs.

The method is also good and safe, since direct intervention in the injectors is not required.

The idea is to leave the car in a warm place. It could be:

• underground parking;
• garage;
• closed parking;
• warm box;
• shopping center parking;
• warehouse space;
• hangar;
• factory workshop;
• enterprise object, etc.

The most important thing is that the temperature is above zero. And the higher it is, the faster the frozen liquid will begin to thaw.

If there are no such warm places at your disposal, then move on to the next method.

Grass "Anti-ice"

The Grass Anti-Ice defroster is quite inexpensive and has a number of advantages. It significantly facilitates the removal of ice and is quite effective in combating minor icing. If the ice crust is strong, you will still need a scraper to completely remove it. The product cannot boast of incredible speed of action, but it is good in terms of quality and price. At the same time, it is practically not counterfeited. The product smells pleasant, does not leave any marks on the glass and does not harm the paintwork. It costs between 150-250 rubles. It is considered quite economical, but if there is heavy ice, a large amount of compound may be required or you will have to actively help yourself with a scraper.

In light frosts, the drug is suitable as an apprentice: it will melt slightly frozen glass. But at double-digit negative temperatures, you can leave it alone - the scraper is definitely more useful.

Expert

Expert is very expensive, but it fully lives up to its name. It is a true expert in fighting ice. Just five minutes is enough to melt even a thick crust of ice. The drug fights small ice much faster. In this case, you practically won’t have to use a scraper. The defroster is applied very easily and quickly, practically without getting on adjacent parts, as it has a convenient sprayer. It is safe for humans and does not harm the paint on the car body. The composition does not leave any traces behind. Its only drawback is that it may become ineffective after being exposed to the cold. Therefore, the bottle with the drug should not be left in the car for a long time. In addition, its cost seems very high to many car enthusiasts. It costs about 350-400 rubles.

Homemade anti-freeze

Take 1 tbsp. l. glycerin per 10 tbsp. l. denatured alcohol Rub the glass thoroughly with this mixture. And then wipe dry with a soft cloth. This procedure can also be done to prevent glass from icing. You can also wipe the windows inside the car with it - they will not fog up.

You can use another method. Take 1 tbsp. l. turpentine, 3 tbsp. l. glycerin and 5 tbsp. l. colorless liquid soap. Everything is mixed and the glass is wiped. As in the first case, this recipe is also suitable for preventing the formation of ice. Just don’t use a solution of regular soap instead of liquid soap.

We recommend: Replacing valve stem seals on a VAZ 2109 car

If the thickness of the ice is quite impressive, then use this proven method. Pour rubbing alcohol into a regular spray bottle and add a little dish soap. Shake well and spray onto glass. The more of this product you spray on the ice, the faster it will melt.

Here's another way to make anti-freeze. Cheap vodka, triple cologne and water are taken in equal proportions. This mixture can be poured into the windshield washer reservoir. It smells like cologne and can withstand temperatures down to -40°C.

Ready-made products

. The range is very wide. Most often they come in aerosol or hand-held spray form. After spraying such products onto the ice, you need to wait a few minutes. Melted ice should be removed immediately by hand or with a rubberized scraper. Be careful if this product contains methyl alcohol. Spray it only downwind. Also avoid getting it on your skin - methyl is poisonous.

Remember that there are also universal products for defrosting car windows and locks on sale. It is worth considering that they contain oil. There will most likely be streaks on the glass. It’s up to you to decide whether to buy a ready-made product or choose a way to make a car window defroster (anti-ice) with your own hands. In any case, the process of melting ice will become much easier and faster.

Car owners in winter very often do not bother to put on warm clothes - the car is in the yard or in the nearest parking lot. You just have to turn on the heater, brush off a light layer of snow with the wipers, and within a minute you can go about your business in warmth and comfort.

But it happens that last night it rained with snow, which froze thoroughly overnight. The glass is covered with an ice crust that completely blocks the view. The problem needs to be solved quickly - you have to be at work before your boss, and the frost is making itself felt. So, open the trunk and find the following items there.

1. Ordinary plastic scraper

. Some people consider this inexpensive, standard cleaner to be extremely dangerous on glass as it can scratch the fragile surface. On the other hand, hundreds of thousands of drivers every morning refute this popular opinion - the pressing force must be inhuman.

Alternatively, you can use calcium chloride or alum. The disadvantage is that you always need to carry liquid with you, which can freeze itself. Or the solution must be very concentrated.

The most extreme option is to rub the surface of the glass with pure table salt. You should be very careful - the glass can be severely scratched.

Saline solution

4. Laundry soap.

Another popular folk remedy for fighting ice. Recently, it has been rapidly losing its former popularity.

Laundry soap

5. CD.

If there is absolutely nothing in the trunk, and you need to drive quickly, a disc from the radio will help save the situation. Most likely, its surface will be damaged and it will no longer be possible to use it for its intended purpose. In addition, it consists of a fairly fragile material. With active use, the disc may burst, fragments can injure the driver and scratch the glass. It is better not to use this method often. But as an option for one time, it is quite possible to consider.

We recommend: When, according to the law, should we change summer tires to winter tires in 2022?

6. Anti-ice cover.

Not the most popular method, because you have to stretch it over the surface of the glass in advance and remove it before each trip. There are approximately equal numbers of supporters and opponents of this method.

7. Winter glass washer.

If there is a washer in the trunk, you can pour it on the glass - the chemical reaction will melt the ice faster. If you can’t find the coveted bottle, you can try to borrow some from the washer reservoir. Of course, if possible.

Winter glass washer

8. Vodka, alcohol, moonshine.

An excellent alternative to washer are strong drinks that do not freeze even at very low temperatures. The ice will go away much faster. Negative consequences of use may occur after a meeting with a traffic police inspector. Due to his duty, he can easily distinguish ethyl alcohol from technical liquids. After which he will be forced to ask several additional unpleasant questions. Although many are not worried about this and even use moonshine instead of winter washer fluid.

Ethanol

9. Modern “advanced” drivers use special glass defrosters

. Essentially, it is alcohol production waste with some additives. They produce “anti-ice” or “deacer” in the form of a spray bottle. All that remains for the driver is to generously spray the icy surface. After five minutes, turn on the wipers to remove the slurry of snow. The convenience of this method is minimal exposure to the cold and no need to work with a scraper.

Glass defroster

10. Direct jets of hot air from hair dryers, burners, electric stoves,

It is also highly not recommended to pour boiling water over the glass - a strong temperature difference will most likely cause the fragile surface to crack. And these are correspondingly significant costs.

Cracks due to temperature changes

11. If the glass is frozen from the inside, it is not advisable to touch it - stains will remain, which are not at all easy to get rid of. The only option is to direct warm (not hot) air onto the ice

and wait. In order to avoid this trouble, before parking, open the windows and wait five minutes for the temperatures in the cabin and outside to equalize.

In principle, the airflow should be turned on immediately after the car is started. While the car is warming up, the air warms up and little by little helps in the fight against ice crust. The main thing is that the flow is not too hot - a large crack is not the best gift for a car enthusiast.

SINTEC

The SINTEC defrost is considered very effective, easy to use and safe for people. It works great even at very low temperatures. The composition is able to remove even severe ice in just a few minutes, practically without the use of a scraper. It removes ice even from hard-to-reach places and small cracks. After using the product, a special colorless film remains on the surface, which prevents the rapid appearance of a new ice crust. At the same time, no stains, streaks or glare appear on the glass. The drug does not spoil the paintwork of a car and does not harm rubber and plastic products in case of accidental contact. Its average cost is about 200 rubles.

How to make anti-ice with your own hands

As it became clear from considering the mechanism of action of industrial compounds, there is nothing particularly complicated about them. That is, it is quite possible to make an acceptable product yourself.

To prepare the mixture, you can use the same substances - alcohol and detergent or protective agent. For example, ethanol and glycerin.

Here, the use of ethyl alcohol is quite acceptable from the point of view of personal safety and prevention of abnormal use. However, isopropyl alcohol, which is part of window glass cleaning liquids, will work just as well.

Glycerin can be replaced with kitchen detergents. One part glycerin or dishwashing detergent to nine parts alcohol is sufficient. It is not necessary to add water.

You can spray the pre-prepared mixture from an already used trigger spray. The recipe will work no worse than the store-bought composition, but will cost much less. Thick ice crusts will require several sprays.

ASTROhim

ASTROhim works great even in very cold weather. It quickly and effectively removes even thick layers of ice, for example if the car has not been cleaned for several days. It will only take a few minutes to remove light ice. If there is significant icing, a scraper may be necessary, but the product still noticeably speeds up the cleaning process. It is very economical and easy to use. One bottle lasts a long time. Does not damage paintwork, but smells strongly of alcohol. A domestically produced defroster costs approximately 200-250 rubles.

LAVR De Frost -80 °С

The Russian product for defrosting car windows LAVR De Frost -80 °C is very effective even at extremely low temperatures. It instantly acts on a frozen surface and very quickly melts even very strong ice. The drug is much more effective even than many well-known foreign analogues. At the same time, very little composition is needed for processing. Therefore it is very economical. The use of a scraper when using this defrost is not necessary. The chemical protects the glass from scratches and leaves no marks, streaks or stains. It does not harm the car's rubber elements or paintwork. The composition is also harmless to humans in case of accidental contact with the skin. Such a defroster costs about 250 rubles. Its price is quite justified for such an effect. By the way, the drug can also be used to clean lock cylinders and car optics.

Why is my car glass frozen on the outside?

The problem of ice appearing on the outside of the windshield occurs only after stopping the car and parking for a long time with the heater turned off, as well as the heating or glass blowing systems. The stronger the frost, the greater the likelihood that a car left overnight will greet the owner with frozen glass in the morning. There are several reasons for this unpleasant phenomenon.

• If there is snow outside, then after the car stops, its flakes, falling on the still warm glass surface, melt, turning into water. As the glass cools, the melted snow turns into ice.
• The consequences of freezing or regular rain, after which frost suddenly struck. Water on the surface of the car, including the windshield, will turn into ice.
• Effect of condensation. It is known from physics that condensation is formed as a result of temperature changes. As for glass, despite the visible density of the structure, it has high thermal conductivity. Therefore, warm air leaves the cabin through it without much difficulty, turning first into drops of water and then into an ice crust.

LAVR Winter -30°

The Russian universal defrosting agent LAVR Winter -30°C perfectly helps to get rid of snow, frost and ice even at very low ambient temperatures. In just a few minutes, it perfectly dissolves even heavy ice. The defroster can be used not only on glass, but also on mirrors, headlights, lanterns and registration numbers. For maximum cleansing, only a small amount of the product is needed. It is not necessary to use a scraper for cleaning. The composition is economical and convenient. It can be added to the reservoir to dilute the windshield washer fluid if its freezing point is quite high. It will quickly melt the frozen “anti-freeze”. In addition, chemicals can also be used by non-motorists in everyday life, for example, to clean windows. It is safe, does not harm plastic and rubber products, does not damage car paint and does not leave any marks behind. The average cost is approximately 250 rubles.

How to eliminate frosted glass

To prevent the windows from freezing, the driver needs to somehow reduce the air humidity in the cabin, simultaneously getting rid of the ice that has already formed. Let's consider options for solving the problem.

1. The most obvious option: open the car doors, thoroughly ventilate the interior, then close it and turn on the heater at full power. Let the heater run for 20 minutes. In most cases, it solves the problem.
2. If the car has heated windows, then along with ventilation and turning on the heater, heating should also be used. Ice from the windshield and rear window will disappear much faster.

Traditional methods of de-icing

Some drivers prefer not to spend money on all sorts of tricks, but use proven old-fashioned methods to remove ice.

Homemade anti-ice liquid. It is prepared very simply: take a regular plastic bottle with a spray bottle (for example, from a windshield wiper). Ordinary table vinegar and water are poured into the bottle. Ratio: water - one part, vinegar - three parts. The liquid is thoroughly mixed and sprayed onto the glass in a thin layer. Then the glass needs to be wiped with a thin cloth. This procedure is best done before leaving the car parked overnight. Then in the morning you won’t have to deal with frozen glass.

Video: review of various anti-fogging agents

So, the main problem causing glass icing is high humidity. It is this problem that the driver must focus on if he does not want to constantly scrape pieces of ice from the windshield. Fortunately, in the vast majority of cases, it is enough to simply change the carpets in the car and ventilate it thoroughly.

Nextzett Anti-Frost

Nextzett Anti-Frost is a product with unique properties and characteristics. It melts and removes even heavy snow and ice almost instantly. For an amazing effect, a small amount of the drug is required, and the use of a scraper is not necessary. The composition perfectly protects the surface from subsequent icing for some time. In addition to icing, it perfectly removes various stains and dirt, even very complex and difficult to remove, from glass. This provides long-lasting protection against glare. The defroster can also be used on car headlights and lanterns, and side mirrors. It is invisible on the surface. After use there are no stains, streaks or other traces left. The drug does not harm paintwork, rubber and plastic products. It is safe for human health, since its main component is ethyl alcohol. The only disadvantage of this chemistry is its inaccessibility in Russia and its high cost. But at the same time, the product is practically not counterfeited.

There are also many other means for defrosting glass on the Russian market. Motorists consider some of them quite effective. But their popularity is much less than that of the compositions presented in the list. And some car owners even prefer to prepare such drugs themselves according to recipes presented on the Internet. But their effectiveness and safety have not been tested.

Now you know which car window defrosters were recognized as the best in 2022. Are you familiar with these tools? What defroster do you use? How effective is your product? If you have questions or want to tell us something interesting on the topic, write in the comments.

Which car window defroster to choose?

Compositions for removing ice from car windows are mainly made on the basis of monohydric (ethanol, methanol, isopropanol) and dihydric (glycols) alcohols. The use of these substances is due to two factors:

• Frost resistance . The freezing point of most alcohols used, even in solution with water, is noticeably below 0 °C.
• Exothermic dissolution . Many alcohols release heat when dissolved in water, which increases the efficiency of the defrost.

The freezing point of a liquid and the amount of heat released during dissolution directly depend on the concentration of alcohol in it. For example, a solution of 20% ethyl alcohol in water freezes at -9 °C, and 72% only at -50 °C. Accordingly, it is better to choose a defrost with a higher content of the main active ingredient .

At concentrations less than 50%, methanol shows the best frost resistance, but since this alcohol is much more toxic than ethanol and is practically odorless, its use for automobile fluids is prohibited in the Russian Federation to avoid poisoning. Therefore, the most common defrosters are those based on isopropanol.

, which is also quite toxic, but has a strong unpleasant odor.

The second factor that must be taken into account when choosing a liquid for defrosting glass is the release form. The most common are aerosol and spray, each of which has its own pros and cons:

Glass defrosters in spray and aerosol form

• Aerosols . They are contained in a pressure cylinder, so they penetrate better into cracks and can cope with the defrosting of the lock. The solvent in this case is liquefied gas, so there is practically no water in them, which ensures a high concentration of active substances. Disadvantages - they cool when sprayed, and butane, usually used as a propellant, does not evaporate at subzero temperatures. Therefore, it is not advisable to constantly store aerosol cans in the car in winter. It is better to keep an aerosol glass defroster at home and take it into the car only before a trip.
• Sprays . Sprays due to the user's effort pressing the trigger. They are not prone to freezing and spray well in moderate frosts (down to -20 °C), so you can always keep them in your car. Often, glass defrost spray is cheaper than aerosols, which is also a plus. The main disadvantage is the use of water as a solvent, the presence of which increases the freezing point of the active substance, thereby negatively affecting the effectiveness of the product.

In addition to the active substance and its concentration, when choosing a defrost, you should pay attention to the auxiliary components. The alcohols themselves dissolve ice by lowering the freezing point of water, but they quickly evaporate and do not provide a protective effect against re-freezing. To achieve this, manufacturers often use silicone and surfactants that form a water-repellent film on the surfaces being treated.

The smell of glass defrosting agent is a negative point that also needs to be taken into account. Liquids based on isopropanol have a particularly strong smell. The absence of a pronounced odor indirectly indicates a low alcohol concentration or the use of cheaper methanol . Therefore, if you need an effective defrost, you will have to put up with the presence of an unpleasant alcohol aroma, albeit masked by fragrances.

Safe ways to defrost car glass in winter

What does a driver usually do in the absence of a scraper and other means? There is nothing left to do but warm up the window with the cabin heater. Long, but reliable: the stove warms up the interior for 15-20 minutes and the glass thaws safely. The main thing is to direct the air flow to the central air ducts or downwards, otherwise there is a risk of getting a crack in the windshield. But what to do when there is no time for full warm-up?

As an option, cover the frontal area with a sheet of cardboard or a car blanket, pressing it with the wipers. The method is unattractive, but effective. In the morning, just remove the “protection” and the car is completely ready for the trip. In fact, this is one of the fastest ways to get started. But we recommend that you abandon such an idea and spend at least five minutes warming up the engine and interior. Firstly, the glass will not fog up from the inside, and secondly, a warmed-up engine does not care about normal loads.

Let's leave the exotic and return to the usual methods of removing morning ice. An alternative to scraping is chemical preparations. These are various types of defrosters or so-called “defrosters” and solutions prepared at home.

Branded glass defroster

The operating principle of the defroster is based on thawing ice under the influence of alcohol. The labels promise to melt the ice in literally 3-5 minutes, after which the remaining sludge can be removed with a cloth or wiped off with wipers. The classic composition of such a liquid can be read on the back side right in the store:

• Isopropyl alcohol.
• Glycerol.
• Surfactant
• Water.

There are quite a lot of tests and reviews about these drugs on the Internet. For example, Za Rulem tested the Russian assortment in mid-winter 2022. Domestic manufacturers of bitumen stain cleaners, already known to us in the technology of scrubbing bitumen from a car body, won. We present the final score below:

• Agat Multispecies.
• ASTROhim AC-135 Anti-ice.
• Grass Anti-ice.
• AVS Crystal AVK-126.
• Eltrans EL-0604.02.

Liqui Moly and Pingo, well-known in the segment of antifreeze fluids for cars, showed so-so results, which is why they are not recommended for purchase. The editors also noted that trigger designs (a bottle with a spray) are better than their canned counterparts. The difference is especially felt in severe frost, when isopropyl alcohol becomes more viscous and has difficulty flowing through the nozzle hole. The advantage of bottle filling is that you can throw the sprayer on the edge and simply pour the glass from the neck.

Homemade defroster from winter washer fluid

The experience of using a regular anti-freeze for defrosting purposes is wandering around the network. The result of manual use of a winter washer, it must be admitted, is so-so. The fact is that many antifreeze liquids do not include one important component that is present in the defroster - glycerin.

Why do you need a glycerin supplement? Alcohol tends to evaporate, and the defroster needs to remain on the glass surface for at least two minutes. During this time, the concentration of the main component, isopropyl, should not change downward, that is, the alcohol should not decrease. Otherwise, the result will be completely the opposite effect - the anti-freeze will leave only water, which will immediately freeze on the glass.

Glycerin retains alcohol, which means it is an essential component of either a homemade potion or a store-bought drug. To obtain a homemade composition, it is enough to add glycerin to the winter washer fluid at the rate of 1-2% of the volume of the final container. It makes absolutely no difference what kind of washer is used as a preparatory component - homemade or store-bought, immediately ready for use, or a concentrate that requires the addition of distilled water.

The main note is to take into account the crystallization temperature of the antifreeze. If the alcohol concentration is insufficient, even the drug diluted with glycerin will not be able to melt the ice.

Hot water

Under no circumstances should you use this method. If your glass is not fresh from the factory, then most likely it has microcracks. Any water that gets into them will definitely freeze. Since water expands when it freezes, the cracks will become larger. If you repeat this procedure several times, then in the near future your windshield will be decorated with a huge crack, or even several at once. Buying and replacing a windshield will cost you much more than glass defrosting products. As a last resort, use warm water and wipe the glass very thoroughly. You can apply hot heating pads, but to be honest, this method is not effective either, due to its small area.

Ethanol

You can use a liquid containing ethyl alcohol in sufficient concentration. The solution is applied evenly for a couple of minutes and then the remaining ice must be removed with a rag. Both technical and food grade (ethyl) alcohol are suitable. Usually, hawthorn tincture is purchased at the pharmacy for such purposes. But in general this is not important; any alcohol-containing solution will do.

Antifreeze + alcohol

Often they simply spray “anti-freeze” on the glass, although it is only suitable in cases of light frost, otherwise it will only get worse. This liquid is an aqueous solution of isopropyl. In fact, it is designed not to freeze quickly, but only on already WARM glass, while cleaning in motion. So, if you try to remove the snow, it will only turn into a dense ice crust. It is better to supplement this product with C₂H₅OH concentrate.

Alcohol + water + glycerin

Mix any alcohol (technical, formic, homemade) with plain water in a 2:1 ratio. Season the whole thing with a few milliliters of glycerin (the same 1-2% of the final volume of the resulting composition) and pour it into a spray bottle - the product is ready for use.

Translating the recipe into a practical plane, you can use the technique of our editorial guest - auto mechanic Evgeniy P. He suggests using the remaining glass cleaner and a medical preparation:

1. Pour 100 ml of window cleaner into a special container.
2. Add 200 ml of hawthorn tincture.
3. Mix well.

Salt based solution

Pour regular tap water into a liter container, add 6-8 tablespoons of regular salt, mix well. Treat frozen glass using a spray bottle. This product reliably corrodes ice at any sub-zero temperature.

Types of defrosters

Car enthusiasts and sellers refer to all defrosters in one word - “anti-freeze”. However, you should know that they differ in the type of impact.

There are two types of defrosters:

1. Warning. These products are used to prevent the formation of ice crust. This includes products from the “anti-ice” series.
2. Destroying ice. Designed to defrost and remove already formed ice crust from glass and housing, without the risk of damaging them.

To avoid misunderstandings, it is always worth clarifying what type of impact the car enthusiast has in mind in order to avoid misunderstandings and disappointment.

Car enthusiasts should know that there are also key defrosters and universal ones. Universal ones are suitable for both locks and glass.

Some car enthusiasts prefer to make a glass defroster with their own hands. However, they are generally of lower quality than factory-produced products. After removing ice with homemade compounds, stains and stains remain.

How is it different from windshield washer?

Windshield washer is a liquid for cleaning the windshield from dirt that gets on it. There are two types: winter and summer.

Winter windshield washer is designed to solve the problem of cleaning the glass surface during the cold season. It is produced on the basis of methyl, ethyl or isopropyl alcohol, sometimes on sale it can be seen on the basis of monoethylene glycol.

Unlike anti-ice, a windshield washer cleans the windows and headlights of debris. This liquid is poured into the windshield washer reservoir, then sprayed through special nozzles and cleaned off by the wipers.

Composition and principle of action

The vast majority of modern glass defrosters consist of several active components.

• Alcohols. The most commonly used is isopropyl alcohol, the same as in winter windshield washer fluids. This alcohol is an excellent solvent that effectively penetrates the pores of the ice crust. Some other alcohols are capable of undergoing isothermal reactions with water, that is, reactions that release heat. The thermal output during these reactions is small and will not allow the glass to suddenly heat up to critical temperatures.
• Aliphatic hydrocarbons. These are compounds of carbon, hydrogen and some other substances without the formation of benzene rings. Depending on their position in the homologous series, they have different solvent properties.
• Propylene glycol ether. It is also an effective solvent that is widely used in the production of various water-based substances. Actively used in the manufacture of industrial cleaning products. It plays the role of a dispersant in glass defrosters.
• Other active components designed to increase the surface activity of basic substances, accelerate isothermal reactions and more effectively penetrate through the pores in the ice crust for active melting.

Some manufacturers do not indicate the exact composition of their products, but only indicate the general affiliation of the components to a particular group of chemicals.

The operating principle of all defrosters is combined. First, warming up the ice crust. Secondly, its dissolution and division into as small areas as possible and separation from the surface of the glass. And thirdly, cleaning the glass from dirt.
