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.
