Dirt Juice Boss Chain Cleaner

The Boss goes straight on to grimy chains, cassettes and jockey wheels and issues filth its P45. It's a drivetrain specific cleaner but it’ll work on any bits on your bike that are properly caked with grease and grime.

Boss is designed to be more powerful against grease, oil and grime than Dirt Juice Super, our classic Super Concentrate Bike Cleaner, and brewed for the grottiest of grime. Use it in combo with our Dirty Little Scrubber Chain Cleaning tool or paint it on directly with a brush, either works!

Not only will Boss clean your drivetrain like you've never seen before, it's also biodegradable and safe to use on metal, plastic, rubber and seals.
