For use with clipper blades. Clipp-Aid is a unique clipper and trimmer maintenance product for barbers and stylists. What's cool about Clipp-Aid is that using it once every 2-3 weeks removes all the hair, dirt and grime that gets stuck between your blades. It keeps your clipper and trimmer blades sharp at all times. The sharper the blade, the crisper the cut. Clipp-Aid® Sharpening Crystals are a unique product for clipper maintenance. They both clean and sharpen metal blades to a like-new state in a super-easy procedure that takes less than 2 minutes. To use, simply select the correct pack for your blade and then turn on the machine and immerse the blade teeth in the crystals, letting them crunch their way through them until they turn to powder. Then clean off and oil well.
