How to Degrease a Chain

Bicycle chains serve as magnets for grime. Grease and grime form when chain lube combines with dirt, sand and other roadside matter. The sludge threatens more than just clean pant legs -- it also undermines the mechanical well-being of your bicycle. The dirt increases wear to the chain and to such drive-train components as the cogs and derailleurs. Cleaning the chain periodically reduces unnecessary wear while helping maintain a smooth-operating drivetrain.

Instructions

    • 1

      Shift the bicycle into its biggest gear. This gear moves the chain to the outside front and rear cogs for easier access.

    • 2

      Combine dish detergent and hot water in a bucket. Add enough detergent to the water to create a thick head of foam.

    • 3

      Dip a scrub brush into the soap and water. Scrub the entire length of the chain. To access the full chain, use the pedal to rotate the chain forward.

    • 4

      Pour fresh water over the chain to rinse away excess soap.

    • 5

      Apply a cleaning solvent, such as kerosene or a bicycle specific degreaser, over the entire chain. Again rotate the chain as needed. For non-spray solvents, use an old toothbrush to apply the solution to the chain. If possible, select a bio-degradable solvent for this procedure.

    • 6

      Allow the cleaning solvent time to finish dripping. Each drip removes grease and residue from the chain.

    • 7

      Place a rag around the bottom of the chain and hold it while using the pedal to rotate the chain backward. Do this for each side of the chain to thoroughly clean it of solvent and any remaining grime.

    • 8

      Apply bicycle lube across the the top of the chain. Rotate the chain to cover it entirely.

    • 9

      Rotate the pedal forward to work the lubricant into each of the chain links.

    • 10

      Use a rag to wipe the chain dry of any extra lubricant.
