When the wheel has a high temperature, you must not clean it directly with cold water. It should be cooled by natural cooling, otherwise, the aluminum alloy hub will be damaged and even the brake disc is deformed and the brake effect will be affected. In addition, cleaning aluminum wheel hub with cleaning agent at high temperature will make the wheel hub surface chemical reaction, lose luster and influence beauty.
If you drive a car everyday, you should wash the rim at least once a week. When cleaning, you can use a detergent to sponge or brush, and then rinse with plenty of water. But do not use too hard brushes, especially iron brushes, because this will damage the surface of the hub. In addition, there is a metal protective film on the hub itself, so special attention should be paid to the use of paint brighteners or other abrasive materials.
Besides, in the southern humid areas or coastal cities, wheels should be cleaned more frequently, so as to avoid the corrosion of rainwater or salts on the aluminum surface.
