PROFESSIONAL CHAIN SCRUBBER PARK TOOL CM-25

The Park Tool CM-25 is the professional chain scrubber built for the workshop, the shop-grade version of the classic Park Tool chain cleaner. With the Park Tool CM-25 professional chain scrubber the chain is cleaned right on the bike, without removing it, so drivetrain maintenance becomes a quick job to repeat at every service. A clean chain works better with sprockets and chainrings and is easier to assess during a workshop check.

Body and handle are die-cast A380 aluminium: a construction designed for daily use and to last for years under heavy workloads. The CM-25 is also 100% serviceable and rebuildable, so every wear part can be replaced instead of throwing the tool away. Inside, four brushes clean the chain inside and out, while dual-sided sponges and wicking pads hold back solvent as the chain exits and reduce drips on the floor and the bike.

How the Park Tool CM-25 professional chain scrubber works

• Pour solvent into the reservoir, close the body around the chain and turn the pedals.
• The four brushes clean the chain inside and out, removing dirt and old lubricant.
• Dual-sided sponges and wicking pads wipe the chain as it exits and limit drips.
• Once cleaning is done, empty the reservoir, let the chain dry and lubricate it again before riding.
• The brush and sponge cartridge clicks in and out for quick cleaning or replacement.

Why choose the Park Tool CM-25

• Die-cast A380 aluminium body and handle, designed for the workshop rather than occasional use.
• Fully serviceable and rebuildable: an investment that lasts for years.
• Four-brush system for thorough cleaning of the inside and outside of the chain.
• Click-in brush cartridge and dedicated spares: RBS-25 brush cartridge and 2336K sponge/pad kit.
• Specified by Park Tool for multi-speed and single-speed chains.

For the mechanic who cleans chains every day and for the demanding rider who wants a shop tool in the garage too, the Park Tool CM-25 professional chain scrubber combines the toughness of metal with the convenience of a click-in cartridge.
