The Morgan Blue Clean and Protect 1L has been specifically developed for MTB and Cyclo Cross bikes. Spray onto your frame and mud and sand will not stick. The surface you are applying the clean and protect to must be clean and dry. Spray the Clean and Protect onto the surface and rub in with a dry, clean cloth. After your ride the minimal amount of dirt on your bike will be super easy to remove. Do Not spray the Clean and Protect onto your rims, brakes/disc brakes as it will make them slide and not brake.
