How to remove a stain of rust on the body of a vehicle

Why are there rust stains on your body?

Several sources can cause the appearance of unsightly spots on your body. First, let’s talk about brake filings. Indeed, in use, the brake discs project very thin metal particles that stick to the bodywork. Exposed to air and moisture, these particles tend to oxidize, with small rusty spots on the surface of your car.

In addition, salt can cause rusty spots on your car. It can be sea salt if you drive regularly near a seaside. But it can also come from salting roads during snow. To reduce the risk of accidents, the roads are salty to prevent the occurrence of ice. The coarse salt used for this preventive measure attacks the bodywork and makes these oxidation marks appear on the cars. But it can also come from other products harmful to your body despite all the precautions taken by the manufacturers. Oil, battery fluid and air pollution are also the cause of corrosion of your car.

Finally, it is of course moisture and water in general that promote the appearance of all these traces of oxidation on your car. Models built and put into circulation before the 2000s are also more concerned by this risk (the steel of cars designed after 2000 being treated against this risk).

Some areas on cars are more likely to be affected than others. This is particularly the case of the bottom of the car, because these elements are located closer to the road and therefore more exposed to projections from the road.
