Riders who want a quick, thorough drivetrain clean at home.
The Grunge Brush is a dual-ended tool. Horseshoe shaped bristles on one end are for greasy chains, crusty jockey wheels and chainrings, while long, straight bristles on the other end reach cassettes and derailleurs.
Use it with plain water or, for a deeper clean, with a Finish Line degreaser. Finish Line says it scrubs away stubborn grime and loosens grease and debris for a smoother-running drivetrain.

How the maker says to use it
Put the chain on the smaller rear cogs and middle chainring, apply water or degreaser, then turn the cranks backwards while cleaning the chain with the horseshoe bristles. Use the long bristles on the cassette and pulleys, wipe, let it dry, then apply chain lubricant.
