Chain Cleaning (On the Bike)

Procedure

1. Shift to the middle of the cassette and middle chainring

   so the chain runs straight.

2. If using a chain cleaning device

   (Park CM-25, Muc-Off X-3):

   • Fill with degreaser to the marked line.
   • Clamp around the chain on the lower run.
   • Pedal backward 30–40 rotations.
   • Empty the dirty fluid; refill with fresh degreaser; repeat once.

3. If brushing manually

   • Apply degreaser to the chain by dripping or spraying.
   • Use a stiff bristle brush along all four sides of the chain — top, bottom, both inner faces — while pedaling backward.
   • Pay attention to the gaps between rollers and side plates.

4. Rinse with water

   (a spray bottle, not a hose blast) if using water-based degreaser. Solvent-based degreasers wipe off without water.

5. Dry the chain thoroughly

   Spin the cranks vigorously, then wipe with a clean rag, holding the chain in the rag and pedaling backward through it.

6. Wait for the chain to fully dry

   (15+ minutes if wet) before lubing.

7. Apply lube

   (see section 12.4).
