My clippers, trimmers, blades, and shears get brushed or wiped, then sprayed down with Clippercide when I'm done with them with each client. Combs get brushed off and put in the barbicide jar after each client. I strip the dirty razor and hang the business end of the handle in bsrbicide.

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!
