How to Remove Car Rust Spots?

First, try using a clay bar. Wet the clay bar and vigorously rub it on the rust spots on the car body, then rinse with clean water. If that doesn't work, you can use a specialized iron remover spray on the rust spots and then rinse with water. If the above methods don't solve the problem, you can lightly polish the paint surface to remove the rust spots. If after rain or when road sewage splashes onto the car and isn't washed off in time, the iron elements in the dried sewage can oxidize and cause rust spots. In such cases, after washing the car, you can use a clay bar with water to wipe them off, or spray and wipe with a tar remover for easy cleaning.

Last time when rust spots appeared on my car door edges, I used a folk remedy: mixing white vinegar and baking soda into a paste, applying it on the rust spots for half an hour, then scrubbing off the surface rust with a stiff brush. If the bare metal is exposed, don't be lazy - use 2000-grit sandpaper with water to smooth it out, dry it thoroughly, and apply anti-rust primer. DIY methods can only handle small rust spots, about the size of a fingernail. For large areas or rust-through holes, you should visit a body repair technician. Remember to dry water accumulation in door seams after washing your car, especially under the plastic panel near the wipers - this dead angle where water collects most easily causes rust, and many people overlook it.

My routine for dealing with car rust involves three steps: First, apply rust remover paste to the rust spots to soften the surface rust, wait fifteen minutes for the chemicals to take effect; then carefully scrape it off with a metal scraper that has a rubber grip; finally, polish it with car scratch wax. All these tools can be bought at auto parts stores, but the key is to remove the rust completely! If you notice paint bubbling, don't pick at it—that's a sign of rust underneath. Here's a lesson that cost me: Never trust roadside quick repair shops when they say ceramic coating prevents rust—that stuff only protects against acid rain corrosion and is basically useless against metal rust spots.

Just finished dealing with rust spots on the car roof—small areas of rust that I handled myself. For surface rust, I sprayed some WD-40 rust remover, let it sit for 20 minutes, and then scrubbed it clean with a nylon brush. Exposed metal areas need immediate epoxy primer coating to prevent oxidation—touch-up pens are only suitable for covering scratches. Pay special attention to hidden spots like the edges of the windshield seal and wheel arch seams, as rust there is hard to detect. If you see orange rust with black dots, it means the rust has penetrated deep into the steel panel, requiring cutting and patching.
