An oil based cleaner that helps protect your rubber with cleaning agents that help take off the dirt/dust from the surface of the rubber.

Spray once conservatively on each rubber and wipe clean with a cleaning sponge. For maximum results, allow the rubber to soak in the oil for approximately 20-30 minutes before wiping clean. You will notice that the rubber will feel slightly slippery at first, but after it is dry (by sponge or by air), the rubber will be softer and faster with more spin easily generated.
