Futura tire cleaner
Futura cleaner has been developed to solve the problem of traction build up on your tires to keep the performance similar the next time you use them. The only way to do this is to remove the traction buildup to keep them consistent from run to run and this cleaner will remove that buildup from the tires. Cleaner is formulated for both rubber and foam tires and especially on foam tires it’s able to open the foam pore, making the tire softer and prepare it for the application of new additive.
