Plastic squeaks and rattles can be annoying and distracting, especially in a car. There are several methods to reduce or eliminate these noises. Firstly, identify the source of the noise by pressing on different areas. Then, depending on the location, you can apply lubrication or a thin layer of adhesive material such as felt tape, foam, or vinyl between the plastic parts to act as a buffer and dampen vibrations. You can also try silicone spray or gasket maker to seal gaps and prevent plastic parts from rubbing against each other. These methods are inexpensive and can effectively reduce plastic noise in vehicles.

What You'll Learn

Use adhesive felt or felt tape
If you're looking for a way to stop plastic from making noise, one effective solution is to use adhesive felt or felt tape. This method can be applied to a variety of surfaces, including plastic panels in cars, furniture, and other household items.
Adhesive felt is a versatile product that can be found in most craft stores, hardware stores, and home improvement retailers like Lowe's or Home Depot. It is similar to the felt pads often placed under lamps or vases to prevent them from scratching wooden tables. The felt provides a soft buffer between surfaces, reducing vibrations and eliminating unwanted noise caused by rubbing or rattling.
When using adhesive felt, clean and dry the surface thoroughly to ensure proper adhesion. Cut the felt into the desired shape and size, then peel off the backing to expose the adhesive side. Firmly press the felt onto the chosen surface, holding it in place for a few seconds to create a strong bond.
Felt tape is another convenient option. It comes in rolls with an adhesive backing, allowing you to easily cut and apply it to the desired area. Felt tape is especially useful for lining narrow or curved surfaces where adhesive felt might not fit as well. Like adhesive felt, it provides a soft barrier that dampens vibrations and prevents plastic components from rubbing against each other.
By using adhesive felt or felt tape, you can effectively reduce noise caused by plastic-on-plastic contact. This solution is simple, inexpensive, and can be applied to a wide range of items, making it a handy trick to have up your sleeve!

Apply silicone spray
If you're looking to stop plastic from squeaking and rattling, one effective method is to apply silicone spray. Silicone spray is a useful tool for lubricating plastic components and reducing friction-induced noise. It is often available in aerosol cans and can be applied in a thin, narrow bead to the required areas.
When using silicone spray, it is important to start by identifying the source of the noise. In the case of plastic parts rubbing against each other, focus on the joints of the components that are making the unwanted sounds. Apply a small amount of silicone spray directly to the affected areas. You may need to separate the parts slightly to access the joints properly.
It is recommended to start with a light application and then adjust as needed. Too much silicone spray can attract dirt and debris, so it is important to use it sparingly and only where necessary. Additionally, be cautious when using silicone spray on surfaces that may come into contact with your skin, as it can leave a residue. Always follow the manufacturer's instructions and take the necessary precautions, such as wearing gloves, to avoid any unwanted effects.
Silicone spray is particularly useful for car maintenance, as it can be applied to various components that experience friction and noise. For example, it can be used on plastic steering column covers, rubber window guide channels, and door seals. It provides lubrication and creates a smooth surface, reducing the chances of parts rubbing against each other and producing unwanted sounds.
In addition to silicone spray, there are other methods to reduce plastic noise, such as using adhesive felt, foam padding, or felt tape between panels. However, silicone spray offers a convenient and quick solution, especially for small, hard-to-reach areas where other materials may be challenging to apply. Remember to allow the silicone spray to dry completely before using the plastic item to ensure the best results.

Try hot glue
If you are looking for a way to stop plastic from squeaking and rattling, hot glue might be a potential solution. However, some people think that hot glue might not be flexible enough to serve this purpose.
Hot glue can be applied in a thin, narrow bead to plastic parts that are rubbing against each other. This can help to create a buffer between the parts and reduce the noise.
To use hot glue effectively for this purpose, identify the areas where the plastic is creaking and rattling. Make sure the surfaces are clean and dry before applying the hot glue. Apply a thin layer of hot glue to one of the mating surfaces and let it dry completely. Then, put the plastic parts back together. The glue should act as a cushion between the parts, reducing the noise.
It is important to note that hot glue may not be a permanent solution as it may not remain flexible over time. Additionally, it is always recommended to test any adhesive on a small, inconspicuous area first to ensure it does not damage the surface.

Use butyl tape
Butyl tape is an effective solution for reducing rattling and buzzing noises in vehicles. It is a type of sealant tape that can be used to fill gaps and create seals between plastic and other surfaces, such as metal, glass, and porous materials. Butyl tape is particularly useful for stabilising outer door skins, preventing rattling in overlapping panel layers, and securing loose components.
One example of butyl tape is the ResoNix Butyl Rope, which is a multitasking sound treatment product. It is designed to address localised sound issues and improve vehicle acoustics. ResoNix Butyl Rope can be used to stabilise components like outer door skins, overlapping panels, and clips, preventing them from vibrating or rubbing against each other. By reducing these localised vibrations and rubbings, it helps to minimise unwanted noise and enhance the overall acoustic environment in the vehicle.
Butyl tape is also available from brands like AUTOHAUX and TZGP, which offer sealant tape products specifically for sound deadening and reducing noise in vehicles. These tapes are often used to fill gaps and create seals between different components in a car, such as the windshield, headlight, door panels, and windows.
When using butyl tape, it is important to ensure optimal adhesion by cleaning the surface thoroughly and removing any dirt, oil, or grease. In some cases, lightly scuffing the surface with sandpaper can further enhance adhesion, although this step is typically unnecessary for metal and most plastic panels.
Butyl tape is known for its strong adhesion, temperature resistance, and flexibility. It is designed to withstand extreme temperatures and various weather conditions, ensuring reliable performance. Additionally, butyl tape does not harden over time, maintaining its effectiveness for years. This makes it an ideal solution for preventing rattling and vibrations in vehicles, providing a long-lasting and removable option for car owners.

Put lube between plastic parts
If you're looking to stop plastic parts from squeaking or rattling due to friction, lubrication can be an effective solution. Putting lube between the plastic parts can help reduce the noise caused by their movement.
When dealing with plastic components that are rubbing or banging against each other, lubrication can provide a much-needed buffer. This method is particularly useful for areas that are difficult to reach or where other solutions, like foam, may not be feasible. Lubrication can be applied in thin, narrow beads to these tight spaces, ensuring a flexible and long-lasting solution.
Silicone spray, for instance, is a useful tool for stopping squeaks and rattles in plastic parts. It can be sprayed in small amounts at the joints of the noisy components, providing lubrication and reducing friction. Silicone spray is also effective for lubricating rubber window guide channels and door seals.
However, it's important to note that silicone spray may not work for all plastic noises, and it may have a strong odour. Additionally, if your car is still under warranty, using silicone spray might not be advisable.
As an alternative, you could try using adhesive felt, which can be found in most craft stores or home improvement retailers. By applying adhesive felt to one of the mating surfaces of the plastic parts, you can create a buffer that prevents direct contact and reduces noise. This method has been successful for car door liners, providing a removable solution while keeping the plastic parts securely in place.
