Squirt's Dry Lube is a water and wax-based dry lubricant. It is completely solvent-free and thus 100% biodegradable. After application and evaporation of the water, a dry, grippy surface remains that hardly attracts dirt. The water allows Squirt's Dry Lube to penetrate the gaps between the chain links. With solvent-based wax lubricants, the wax dries on the surface of the chain. However, we need the wax where the chain moves.
