Park Tool Cleaner Chain Scrubber CM-5.3

Precision Clean for Peak Performance

Give your chain the deep clean it deserves—fast, easy, and mess-free. The CM-5.3’s rotating brushes, magnetic grime trap, and smart solvent system leave your drivetrain spotless without even removing the chain.

• Compatible with all multi and single-speed chains*
• Compatible with center and rear drive e-bikes
• Holds 59 mL (2 fl. oz.) of solvent
• Replaceable brushes and sponge (part # RBS-5)

NOTE: All standard bicycle chain sizes will fit through the CM-5.3. However, some single-speed bikes are not fully compatible with the CM-5.3 due to the low clearance between the chain and chain stay.
