Quick, efficient and easy to use. No removal of your bicycle chain necessary! The Shop Quality Chain Cleaner features a 3-Brush rotating brush design and scrubber pads for fast, thorough cleaning. Clips onto chain and in just 60 seconds, your chain is clean. Heavy-Duty industrial quality resin body withstands shop use and will not crack when dropped off a work bench. An oversized super strong magnet at the bottom collects metal filings from the chain. Perfect in combination with the Eco-Tech cleaner.
