Now with an improved ergonomic design! Cleaning chains and gears has never been easier or faster. Scrub the chain with the horseshoe-shaped bristles at one end of The Grunge Brush™ to clean all four sides of the chain. Use the long bristles at the other end of the brush to clean components such as sprockets, derailleurs, chainrings, brakes, and pedals.

Regular cleaning of components prevents premature wear of the chain and sprockets, eliminates chain skipping caused by dirt and grime, and ensures the smooth operation of the drivetrain and brakes.

The Grunge Brush™ can be used dry or for deep cleaning; use it with Citrus Bike Chain Degreaser or Multi Bike Degreaser by simply spraying degreaser on the chain or directly onto the bristles. The scrubbing action of The Grunge Brush™, combined with a Finish Line bike degreaser, will make your drivetrain look like new!
