Input: [header] How to clean rims [title] Allow the vehicle to cool. [step] Don't wash the rims right after driving. Let the car rest with the engine off. <sep> (A) [title] Clean the rims out by gently wiping down the rims with a soft microfiber cloth or paper towel. [step] Most metals such as porcelain, now do not work well with this process. (B) It can take hours for the entire car to cool, but you can test the rim temperature by moving your fingers close. When the rims feel cool to the touch, you can clean them. (C) [substeps] Depending on the vehicle make and model, allowing the vehicle to cool usually takes approximately 24 hours. Do not turn on the car's heat. (D) Cover the pan with a rubber glove so there's no impedance caused by the engine running. Use a hose if it doesn't feel comfortable.
