How to Remove Oxidation Layer on Car Surface?
2 Answers
First, sand off a layer with sandpaper, then apply wax and polish to remove it. The reasons for oxidation layers on car paint are as follows: 1. Long-term accumulation of dust. 2. Corrosion by strong acid or alkaline substances, which accelerates paint oxidation, such as bird droppings, air conditioner water, and tree sap. Moreover, with increasing environmental pollution, rain may contain certain acidity. 3. Exposure to intense sunlight and UV rays in high temperatures can also significantly damage the paint and accelerate oxidation. 4. With worsening air pollution, the increasing presence of chemical substances in the air continuously oxidizes the car paint surface.
When I encounter the issue of car paint oxidation, I usually handle it myself. First, I thoroughly clean the stains on the car body with a neutral car wash solution, rinse it off, and then use a hair dryer to dry any residual water in the gaps. Next, I use specialized clay with lubricant to slide in straight lines over the oxidized areas—it feels somewhat like rubbing with modeling clay, removing about 90% of the oxidation layer. The key is to use a polishing machine with a compound, applying it in circular motions at medium speed. Beginners should remember to start practicing from the edges of the hood. Finally, don't forget to apply a ceramic coating for protection—no more water marks even when it rains. Spending two hours on this over the weekend saves me about 300 bucks compared to going to a detailing shop.
