Muc-Off places a strong emphasis on eco-friendly cleaning products, which is why the majority of their products are biodegradable. The application is simple: Muc-Off's Bike Cleaner is sprayed on, allowed to sit for a short time, and then the foam can be rinsed off, leaving the bike shining like new. The Bike Cleaner cleans all materials such as aluminum, titanium, plastics, and carbon without damaging sensitive areas like seals or paintwork. Muc-Off's Bike Cleaner is fully biodegradable (alkaline base) and contains no harmful acids or solvents. Muc-Off's Bike Spray protects the bike from external influences. It leaves a thin film of lubricant on all parts, thus extending maintenance intervals. Additionally, a high-quality sponge and the "Wheel & Component" brush are included in the package. The brush is perfectly shaped to remove stubborn dirt from spokes and rims. A practical carrying bag, which allows for organized storage of everything, completes this great set.
