Although you will find many cleaning agents available in the market but we recommend using WD-40 Specialist Fast Acting Degreaser. The degreaser can remove soiling such as soot, oil and mud from bicycle chains, chain gears, crank sets and cassettes. It does not leave any residue and helps to reduce wear on the mentioned bicycle parts. Not only this, but you need a cleaner that doesn’t strip the chain of its factory lube. As this shortens the life of a bike. Therefore, WD-40 Specialist Fast Acting Degreaser is the right choice for this job.
We recommend using soft bristled brushes. If you’re unable to get professional cleaning brushes, don’t worry. A simple toothbrush will suffice as well. In fact, it might be more helpful as it can reach the small spaces between the teeth of the chain easily.
