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

Regular cleaning of components prevents premature chain and sprocket wear, eliminates chain skipping caused by dirt and grit, and keeps the transmission and brakes running smoothly.

The Grunge Brush™ can be used dry or for deep cleaning, use it with Citrus Bike Chain Degreaser or Multi Bike Degreaser, simply spraying degreaser onto the chain or directly onto the bristles. The Grunge Brush™ scrubbing action, combined with a Finish Line bicycle degreaser, will have your drivetrain looking brand new!
