When using WD-40 Specialist_® Bike Degreaser on my bike chain, should I rinse with water afterwards?

With the WD-40 Specialist® Bike Degreaser it is really up to how dirty the components are. The formula itself is fast evaporating and leaves no visible residue. So if it’s not too dirty then just spray liberally and use a cloth to collect the dirty liquid, there is no need to use water. If the chain is severely dirty and greasy then it is a very good idea to rinse with water to help ensure that all of the dirty liquid is removed. In some cases you may need to reapply the degreaser to remove all of the previous dirt and greasy grime. Always remember that the WD-40 Specialist Bike Degreaser leaves no residue and therefore is not a corrosion inhibitor. To protect the chain, relubricate with a chain lube or apply a corrosion inhibitor like WD-40® Multi-Use-Product for storage.
