Start by cleaning the blade using a clipper brush to remove large hair fragments from the blade. Then remove debris from hard-to-reach spaces. Step two, clean, disinfect and cool the blade with cooling spray. Then use clipper oil to lubricate your clipper and keep it running at top performance: 3 drops across the teeth of the blade and 1 drop on each back rail. Follow these simple steps will keep the blade lubricated, help it run cooler, and extend the overall life of the clipper.
