Place a piece of cardboard under the bicycle to catch excess cleaner.

Rotate the foot pedal with your hand slowly, and spray WD-40 bicycle chain cleaner evenly throughout the chain.

Only use WD-40 that is specifically made for bicycles. Using normal WD-40 can damage your bicycle chain.

The chemical spray is toxic and very unpleasant to smell. Please use a mask or other means of protection on your face and eyes.
