If the wheels of our cars are rusty, the following methods can be used to solve it.：

1. You can use very fine water sandpaper dipped in water and gently rub it on the rusty place to remove the rust spots and then apply a layer of primer, so as to ensure that the rust spots will not expand. If it is a relatively new scratch, apply the primer directly after wiping, the effect is better.

2. The above method is to directly polish and then spray primer for relatively small rust marks. Although it can solve the problem on the surface, it cannot solve the problem fundamentally, because the primer may fall off after a period of time. In fact, the most correct method is to polish and paint the wheel rim when it is scratched but not yet rusty, so that there will be no rust and corrosion.

3. We need to rinse the edges of the tires of the car with water first, especially the dirt inside. The second is to spray the rust remover evenly on the rust remover in an appropriate amount. After waiting for a period of time, use a sponge to wipe the surface repeatedly, and the rust on the wheels will disappear.

4. You can choose to put oxalic acid on top of the rust, then drop a few drops of warm water, wipe it gently, and then wash it off with water. This operation must be done quickly to avoid corrosion. Lemonade can also achieve the same effect, but it will leave a light yellow color that is more difficult to remove.

Under normal circumstances, our aluminum alloy wheels are not easy to rust, but if they are made of steel or iron, they will rust more easily. It is better to choose aluminum alloy.
