Cleaning the wheels
Do not use acidic wheel cleaning products to remove brake dust. This could damage wheel bolts and brake components.
Do not park the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after cleaning. Braking heats the brake discs and the brake pads/linings, thus drying them.
The vehicle can then be parked.
