Car wheel rims are more susceptible to dirt than other parts of the car. They are often covered with bitumen particles, which are very difficult to clean without damaging the paint coating of the disk.  This solution will help to clean any dirt on disks, including dried bitumen.  The product is applied to the surface with a spray and then wiped with a microfiber towel from the kit.
