Ways to open doors

If you neglected lubrication or simply forgot to apply the product to the seal, the doors froze. There is no point in opening them by force, as you may damage the mechanism and handle. The first thing to do in such a situation is to try to swing the door back and forth so that the frozen water cracks. Another way is to get into the car through the luggage compartment, if of course it opens. When all else fails, try opening doors in these ways:

• Pour 1.5 liters of warm water into a plastic bottle. Pour water slowly from top to bottom at the junction of the body and the door. Warm water will melt the ice and the doors will open immediately. Just make sure that the water is not too hot;
• Spray the joint between the doors and the body with Vedashka and try to open it again.

Never use crowbars or other tools to open doors. They will only ruin your car.

As soon as you get into the car, immediately wipe the doors and rubbers dry and put the car in the garage. Then treat the rubber seals in any way as suggested above. If you have experienced doors freezing, write what methods you used and what helped you. Share your useful experience with us, it is interesting and useful, as it helps to avoid force majeure situations.

To prevent the driver from having problems opening doors in winter, you need to prepare for frost in advance and treat the door seals with a special compound. The best option is lubricant for car door seals , which prevents the rubber seal from freezing.

Tips for the whole year

There are several recommendations regarding extending the service life of door seals that are relevant throughout the year.

All 4 seasons should adhere to these rules. Namely:

• keep your rubber bands as clean as possible;
• remove any abrasive particles;
• do not leave seals wet;
• do not close the machine tightly if it is damp inside;
• use body chemicals carefully;
• read the composition of car cosmetics before applying it to rubber parts;
• After cleaning the dirt, wipe with a damp cloth and then wipe dry.

Moisture is the most dangerous in winter. It can freeze, form hard crystals, and gradually destroy the rubber.

Please note that door rubbers often use metal fasteners and frames. They are unlikely to be made of stainless steel. And if moisture remains there, the process of rust formation will not take long to occur.

Aggressive chemistry can corrode rubber, which also does not lead to anything good.

Why do seals need lubrication?

In general, silicone-based lubricant is a universal product that not only protects rubber seals and other surfaces , but is also used to solve many other problems. Its use greatly increases the life of many decorative and sealing elements in any car.

Spray treatment of rubber seals

The lubricant used for rubber seals protects the elements from cracking, aging, and winter freezing . In addition, this product improves tightness, heat and sound insulation.

But it is precisely the versatility of the existing properties of silicone-based lubricants that allows them to be used for almost all rubber and plastic car parts. Silicone has ideal chemical properties, including water-repellent characteristics and the ability to protect parts from mechanical damage. The operating temperature of such products is in the range from -50ºС to +250ºС. But regardless of the ambient temperature, the viscosity of silicone lubricants does not change.

This allows you to use silicone for car doors and other elements at any time of the year: in winter - to prevent the seal from freezing to the body, and in summer - to prevent drying out and destruction of rubber parts.

Aerosol cans

A very convenient form of packaging of anti-freeze lubricant for car doors . It’s better to first spray it on a sponge or rag, and then rub Suprotec SR-100 silicone wax, for example, over the seal. If you try to apply the spray directly to the elastic, you won’t be able to do it neatly. A certain amount will end up on the upholstery, and cleaning off the thin film is problematic.

The advantage of this packaging is not only convenience, but also versatility of use. Suprotec SR-100 spray is easy to treat both seals and locks. It is enough to bring the can to the keyhole and spray a small amount of product inside. Other forms of lubricant require a little fiddling to coat the inside of the lock mechanism.

You need to be especially careful if you decide to coat the glass seals with silicone wax. It can only be applied to the top and vertical parts. Do not apply Suprotec SR-100 to the underside. When raising and lowering the windows, they become dirty with silicone, and it is very difficult to clean it.

Types of lubricants

When wondering how to lubricate rubber bands, you need to have an idea of ​​what types of lubricants are available to motorists today and what are the advantages and disadvantages of each type. This should be discussed in a little more detail.

Spray for treating seals

Paste products

These are thick plastic mixtures applied using napkins. Paste-like products are used when treating rubber car seals , diving equipment and household appliances. The disadvantages of such lubricants include the difficulty of lubricating hard-to-reach places.

Gel products

This type of lubricant has a thick or liquid consistency and is applied to parts using a soft cloth. The advantages of thick products include the fact that parts that are not being processed remain clean . While their disadvantage is the impossibility of application in hard-to-reach places. Liquid gel-like products are used to treat complex devices, since, on the contrary, they easily penetrate hard-to-reach places. The disadvantage of liquid gel products is their ability to spread, but sometimes this becomes their clear advantage.

Aerosol products

These products are easy to use. They are used for applying to large surfaces and small parts in hard-to-reach places. The disadvantage of aerosols is excessive splashing , leading to contamination of neighboring elements. To reduce splashing, you need to use special long nozzles. In addition, if not rubbed thoroughly enough, aerosol products form greasy stains.

Aerosol sealant treatment agent

Conditioner "Very Lube"

This product is in the form of a spray, which is intended for treating rubber and plastic surfaces. It helps restore color and protect against aging . The spray has excellent cleaning properties, penetrates deeply into small cracks and scratches, and when filling them cleans them of dust and dirt accumulations. The use of such a product helps restore the original color and shine, improve the aesthetic appearance of rubber surfaces, protect against fading and cracking, and prevent freezing of rubber seals on doors, hoods, and trunk. The only drawback of applying the spray is the fragility of the protective coating. This increases the need for their use.

Penetrating lubricant "NanoProTech"

Today, lubricants of this type have become very popular. They have ideal moisture-proof, anti-corrosion, lubricating and penetrating properties . Prevents freezing of moving parts at temperatures down to -80ºС. The lubricant is recommended for use on rubber seals.

And there is no need to be surprised.

Application

Automotive lubricants have a wide range of applications .

Door seals

Lubricants are actively used to prevent cracks and wear of the sealing elements of doors, hood, and trunk . Experts recommend regularly treating these elements with silicone-based lubricants. This contributes to maximum sealing and the absence of extraneous sounds in the cabin. In addition, such lubricants are used to process all kinds of moving elements and surfaces.

Using silicone spray, door hinges and side window grooves are treated. For easy sliding of the hatch and reduction of loads on its surface, this treatment extends the operating time.

In addition, all surfaces treated with such means are protected from wear and damage, corrosion and exposure to external factors.

Locking mechanisms

Regardless of the make and model of the car, all vehicles have a decent number of locking mechanisms. All of them are exposed to external factors and mechanical wear. For example, condensation, accumulating in the secret of the element in winter, freezes, which makes it difficult or prevents the opening of doors, hood, trunk and other parts equipped with a lock. To prevent this, you need to regularly lubricate the mentioned mechanisms.

Using the nozzle for hard-to-reach places

Silicone-based lubricant prevents icing. Excellent penetrating characteristics ensure easy penetration of the product into any hard-to-reach places. Teflon, which is part of the composition, creates an invisible protective layer on the surfaces of parts. This prevents corrosion and various oxidations.

Silicone is highly resistant to salt solutions, alkalis and mildly aggressive acids.

Plastic elements

Plastic parts in the car interior (dashboard, door cards, etc.) often emit extraneous noise; to prevent this, it is recommended to use these chemicals.

Silicone-based lubricant does this job perfectly. Contact and joint lines treated with silicone grease stop making any noise. Also, using these compositions, you can treat any plastic elements, this gives them shine and thereby changes the appearance of the interior.

Suspension parts

Suspension parts made of rubber are exposed to harmful foreign microparticles. When moisture, dust or sand gets on parts, they act on them like abrasives , which leads to their rapid wear. In winter, to reduce the influence of aggressive compounds and reagents on suspension parts, it is also advisable to treat them with a protective agent. Today, all kinds of silicone-based lubricants are on sale, aimed at protecting metal parts of the body and chassis from negative influences that cannot be avoided when operating a car.

Lubricating rubber door seals

Control details

Silicone lubricants extend the life of the sealing bushings of pedals and levers. Moreover, aerosols are excellent for applying to cables. To do this, the product is blown into the protective casing of the cable using a special thin nozzle, having previously disassembled it.

This treatment promotes good gliding and protects against moisture/dust.

Purpose

1. Blocks water and dirt from entering the cabin by flowing down the car body.
2. Prevents drafts from entering the interior by tightly pressing the doorway with a rubber seal.
3. Provides all-season protection from hot and cold air.

   
   Improves the level of sound insulation of the interior from external noise.

4. Promotes soft closing of doors.
5. Increases the shock absorption of doors and body openings when passing asphalt uneven surfaces.

What to choose

The basis of silicone lubricants for rubber seals is mixing a polymethylsilixane solution and propylenes with the addition of various types of polymers. The differences between the products are almost impossible to discern. All of them provide excellent results in moisture repellency and lubrication.

The main differences between these products are the presence or absence of odor, ease of processing and application. Operating temperature conditions also differ slightly (ranges -30°C-+200°C and -50°C-+250°C). The solvents contained in such products erode easily, thanks to which they dry quite quickly.

Treatment of hard-to-reach places

To determine the type of lubricant, you must carefully read the instructions for use and technical instructions. parameters . It is preferable to treat glass seals with a paste-like or gel-like product; for the hood/trunk, gels and aerosols are the best option.

The quality of lubricants is determined by their shelf life, manufacturer’s rating and price - a low cost may have a low quality composition.

What lubricants are not recommended for use?

The lowest quality type of lubricant for car doors is considered to be technical petroleum jelly. It also forms a protective film on the parts, but it disappears after 2-3 weeks or immediately after the next wash. In addition, Vaseline comes only in tubes, which makes its application not always convenient.

Quite often on automotive forums, it is recommended to treat vehicle hinges and locks with a universal compound WD-40 or a product called “liquid key”. It is worth remembering, however, that the main purpose of these products is to displace moisture and dissolve rust.

They do not have proper lubricating properties and are not able to protect parts from wear. These materials, among other things, are washed away within a few days after application.

It is not recommended to treat car hinges and locks with grease and its analogues. Due to their increased ductility, these lubricants can spread strongly, leaving dark stains on painted surfaces. In addition, they absorb dust and other contaminants, which causes rapid loss of properties.

Spindle oil or similar liquid compounds that can be used in other parts of the car are also not suitable for treating doors. They can be used inside locking mechanisms when jammed, but they will drain oil from the outer surfaces.

Let's sum it up

In addition to special products intended for lubricating car door locks, there are also old recipes for car care for car locks that are still used today. Many car owners with extensive driving experience continue to actively use them, for example, they use grease or kerosene. And they continue to save on purchasing a newfangled lubricant.

However, if you really don’t want your car doors to stop opening one frosty winter morning, then it’s best to purchase a product specially created for this purpose rather than rely on traditional methods.

Let's categorize the lubricant compositions described in our article according to the effectiveness and preferences of many car owners:

1. The best choice is lithium grease with the addition of molybdenum disulfide. High quality lubricant, but the price is appropriate.
2. Silicone compounds are universal, suitable not only for metal processing. However, they can wash out quite quickly, so their service life, as a rule, is much shorter.
3. You can also purchase graphite lubricant. This is a less preferred and proven option, but also cheaper. Grease can cause wear on the hinges and locks of the car. However, it is recommended to opt for the other two lubricant compositions described above.

All of the above compounds are on sale and at an affordable price. Therefore, each car owner should decide for himself how to lubricate car door locks for the winter, based on his capabilities and preferences. What product do you prefer for lubricating car locks? You can share your experience in the comments.

Making the right choice for processing loops

The hinges in the machine need to be lubricated several times a quarter; if the operation is not particularly intensive, the frequency of this procedure can be reduced. But is it worth it to start the state of the doors and wait until they cry out to you by creaking and jamming when the car is opened.

To avoid regretting your choice, buy Wurth 2000 synthetic adhesive lubricant. It is also suitable for locks, cables, rollers and gears. Good penetration into all gaps and crevices, formation of a stable and reliable film, protection from all those factors that negatively affect car parts - all this allows us to call this product the best in its segment. A similar product that can also be used on door locks, not just hinges, is Molykote Multigliss.

Since you are treating doors, you should at the same time acquire a Movil spray can, which is very effective at treating the lower edge, preventing the formation of corrosion. Hinges can also be treated with this product, but only if there is no special lubricant at hand. The thick brown liquid, when properly applied to well-cleaned surfaces, can retain its protective and lubricating functions for about a year. And this at a low cost. The only small drawback is the process of applying this product, which requires a brush.

You need to love, protect and take care of your car, then it will respond to you with gratitude and will not let you down along the way. Each element of the machine requires your attention, door hinges and locks can cause inconvenience if they are not monitored and the lubrication process is ignored.
