Park Tool's ChainBrite is a citrus degreaser that was designed to work with their Cyclone Chain Scrubber, but works well as a general degreaser too.
Biodegradable Citrus ChainBrite is specially formulated for use in the Cyclone Chain Scrubber. It quickly removes the toughest grease and grime buildup, yet won't harm alloy, plastic or rubber parts. Also works great as a general purpose parts cleaning fluid. Flip-top lid makes pouring easy. 16 oz. bottle.
