Park Tool CM-5.3 Cyclone Chain CleanerThe Park Tool CM-5.3 Cyclone Chain Cleaner has been Updated to allow for the scrubber handle to be used on either side.

There is a series of roller brushes thoroughly scrub chain clean. The magnet in the base traps metal particles. The sponge dries chain upon exit and helps to reduces mess.
