What can be done to oxidize the plastic shell of car headlights?
The oxidation of the plastic shell of automobile headlights can be treated by the following methods:
Use soapy water: This is a simple method. You can directly wipe the headlight cover with soapy water. It is recommended to wipe it repeatedly with a clean sponge. After wiping, dry it and apply wax. But be careful not to use washing powder water, because soapy water is alkaline, and washing powder water is corrosive.
Use toothpaste: Toothpaste contains certain abrasive ingredients, which can wear away the oxidized substances on the lampshade. Apply toothpaste directly to the yellowed area, wipe it repeatedly with a clean sponge, and finally wipe it clean with a dry towel.
Use WD40: WD40 has antioxidant and cleaning functions. You can gently spray it on the lampshade and then wipe it with a wet towel. However, you must pay attention to safety when using it and try not to make direct contact.
Sanding with sandpaper: This is a crucial step and must be done patiently and thoroughly. Soak a piece of 1000# sandpaper in cold water for 10 minutes, wipe the headlight housing evenly, and polish back and forth in one direction. Always keep the surface moist and use moderate intensity to avoid damaging the surrounding paint or decorative strips. Until all the pits or scratches you want to remove are smoothed, gently wipe them clean with a towel, check whether the polishing is even, and dry the surface after completion.
Use polishing agent: After polishing, you need to apply a layer of polishing agent, and finally spray a layer of clear oil for protection.
Regular maintenance: Car owners can perform regular maintenance on their cars, clean the dirt and dust on the surface of the headlights, and wipe them with a clean soft cloth. They can also prepare soapy water to clean the headlights, which can remove dirt and oil on the surface of the headlights. Wait for adhesion to avoid yellowing.
If none of the above methods can solve the problem, you can consider going to a retail store for professional treatment or directly replacing the headlight assembly.
