CLEANER is designed to get you back out on your bike quickly and safely without wasteful aerosols, harmful chemicals, high-volume soapy fluids or complicated chain-washing-machine-things. Simply spray and wipe CLEANER to remove grime, dirt and oil from the chain. Highly efficient; there are 1000+ sprays in each bottle over a year supply if you clean your chain weekly. CLEANER is non-toxic, biodegradable and petroleum free.
