What Is Muc-Off Bio Degreaser Best Used For?

Muc-Off Bio Degreaser is a water-based, biodegradable degreaser engineered to cut through oil, grease, and chain lube buildup on drivetrains, brakes, wheels, and component contact points. It is powerful enough to handle a heavily gunked cassette or a caked derailleur cage, but gentle enough that it will not damage painted surfaces or anodized finishes when used as directed.

At 500ml in a spray bottle, it gives you plenty of product for thorough cleaning sessions without waste. Apply to the target area, let it dwell briefly, agitate with a brush on stubborn buildup, then rinse with water. It is the go-to general-purpose degreaser when you need water-rinse cleaning for a whole component rather than a quick wipe-style job.
