The ULTIMATE RACING cleaning gum is a sticky synthetic putty that simply picks up all the dirt and dust your car has collected on the track. The gum even absorbs oil and grease! For cleaning your car you just have to press the cleaning gum on the dirty part of your car and all dirt and dust particles stick on the gum. This gum allows cleaning the smaller corners and parts of the car. Once the dirt is on the gum, you have to mix the ball and the gum absorbs the dirt and is ready for the next time. Thanks to its special formulation it can be used a lot of times keeping its qualities. This gum is awesome!
