Using the Muc-Off Disc Brake Cleaner is a breeze. First, make sure your bike is parked safely. Then, shake the aerosol spray well. Hold the can about 10 - 15 cm away from the disc brake pads and rotors and spray evenly. Let it work its magic for a few seconds to loosen the dirt. Wipe away the grime with a clean cloth. You don't need to rinse it as it air - dries quickly. When using it, keep it away from open flames as it's an aerosol product. Also, don't spray it directly on electrical components. To maintain your brakes, use this cleaner regularly, especially after riding in muddy or wet conditions. This will keep your brakes performing at their best and prolong the life of your brake pads.
