How to Remove Rust from a Car Without Damaging the Paint?
1 Answers
Use a cloth dipped in bathroom cleaner and rub it back and forth on the rusty area. It will clean up quickly, but make sure to wash your hands thoroughly afterward. Choose a good machine oil, apply it to a cloth, and gently wipe the rusted area. After removing the rust, use a soft, dry cloth to wipe off any residual oil from the car body. You can add some acidic substances, such as oxalic acid. However, be careful not to use too much to avoid secondary corrosion. It can quickly dissolve iron particles, oxidation layers, and other substances on the paint surface. Just spray lightly, and the iron particles in the paint will dissolve quickly, then rinse with clean water.
