Using Muc - Off Dry Chain Lube is easy. First, make sure your bike chain is clean. Then, apply the lube evenly along the chain, letting it soak in for a few minutes. After that, wipe off any excess lube with a clean cloth. As for precautions, keep it away from open flames and children. For maintenance, re - apply the lube regularly, especially after long rides or if the chain gets wet. This will keep your chain running smoothly and extend its lifespan.
