Perfect for removing browning and other dirt on tires. The Black Tire Cleaner from Dope Fibers is just the right solution when it comes to getting rid of browning on tires. Browning happens due to industrial dust that settles on the tires while driving, and it’s tough to remove with regular car care products. That’s where the Black Tire Cleaner from Dope Fibers comes in handy, and it can also be used before applying our ShinyTireGel from Dope Fibers.
