How to Deal with Yellowing Car Paint Caused by Asphalt Corrosion?
2 Answers
Use a specialized cleaning agent to wash the car body. Remove all oxides from the paint surface through polishing. Perform deep cleaning on the paint surface. Select a polishing compound and test it on the paint surface. Proceed with polishing based on the appropriate test results of the compound. Choose high-quality maintenance products. Maintaining the paint surface is like skincare—it's a continuous process that requires consistent use.
I've dealt with the issue of car paint being corroded and yellowed by asphalt several times. It's caused by the chemicals in the asphalt penetrating the paint surface, creating yellow stains. Don't be careless at the first sign. I recommend spraying a dedicated automotive asphalt remover first, which can be bought at supermarkets or auto parts stores. Wait a few minutes for the agent to dissolve the stains, then gently wipe them off with a soft cloth or sponge. If there's any residue left, take it to a professional detailing shop for polishing to remove the oxidized surface layer and restore the gloss. After completion, apply a layer of wax to protect the paint surface and prevent recurrence. Remember not to use hard objects to scrape during the whole process to avoid deeper damage. Usually, avoid driving through construction areas to reduce the risk of sticking, and this maintenance can extend the life of the car.
