Cleaning brushes reach the places a sponge can't: between cogs, around the derailleur and into tire tread. A soft brush for the frame and a stiff one for the drivetrain cover most jobs.
What it's used for
- Washing the bike. Bosch suggests a brush and a soft sponge with bike shampoo (Bosch). See wash an e-bike safely.
- Scrubbing the chain and cogs with degreaser. See clean and lube a chain.
What to look for
- A soft brush for paint and the display area. Park Tool's BCB-4.2 set includes a soft bristle soaping brush for general cleaning (Park Tool BCB-4.2).
- A stiff brush for heavy dirt. The set has a sponge and bristle brush for heavy scrubbing (Park Tool BCB-4.2).
- A detail brush and a gear brush. The set adds a tapered detail brush for tight spots and a gear brush with a pick for grit in the cogs (Park Tool BCB-4.2).
- Keep drivetrain brushes separate. A brush that has touched chain oil will smear it onto brake rotors.
