Wahl Clipper Oil 118ml is specially prepared for use with Wahl clippers and trimmers. Regular use of clipper oil with your appliance not only helps the blades to run more smoothly, preventing overheating from friction, but will actually help to prolong the life of your blades and their cutting precision. Wahl recommend placing a few drops of clipper oil across the tips (cutting edge) of the blades before and after every use. The oil is easy to dispense from the twist nozzle of the bottle.
