Most clipper cooling sprays dissipate the heat from the blades and also disinfect and lubricate your clipper, all at the same time. The Andis Cool Care Plus 5-in-1 clipper spray is an excellent example of a cooling spray that disinfects, lubricates, cleans, and prevents your blades from rusting.

A barber has to sanitize and disinfect his haircut tools every time, in between every customer. You want everything you use on your client to be clean, with no exceptions. It's also the law!
