Park Tool CM-25 Professional Chain Scrubber

Our favorite consumer chain cleaning system for years was the Park Tool CM-5/CM-5.2. The lightweight and reliable plastic tool held up great for home and travel use. Park has now built a shop quality version with a die cast aluminum case and handle that handle the daily load of a busy bike shop. Smartly, the Minnesota bike service experts created a simple, easily changed cartridge that carries a new brush and sponge system. The proven four-sided scrubbing action makes thoroughly cleaning chains quick and easy. We feel most serious and dedicated home mechanics will opt for the CM-25 Professional Chain Scrubber for their mini-fleet of well-used bikes.

The hinged CM-25 couldn't be easier to use, and it secures properly with a solid feel. Park's CB-4 Bio ChainBrite is the recommended cleaning product, but most non-toxic cleaners can be used with strong results. The replacement brush/sponge cartridge comes in upper and lower pieces, and both are also easy to replace with firm push and click engagement. This RBS-25 part is widely available and costs under $19. It is time to change the cartridge when the sponges are well worn and the brushes are less effective. For shops, that may be once a month, for home techs, it all depends on how much you use it, but we recommend at least once a year, or twice if you commute daily, race cross or simply take chain cleaning seriously.
