From REDS Racing:
Reds Racing Cleaning Putty helps you to keep your car and working area clean. This putty helps you to easily remove the dirt, dust, oil or grease that your car has collected on the track. The gum is great for cleaning your engine, engine block and exhaust system too.
When using the Cleaning Putty, first knead it in your hands until the Putty becomes malleable, and then form it into a small ball. Then, press the Putty onto the dirty section, and then pull it away to remove all the dirt and grime; repeat until the section is completely clean. If traces of the Putty remain, just re-press the Putty onto the remnants and they will be removed.
