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!

Every barber shop should have a container of barbicide at every station. This blue liquid is a shop staple. It is there to clean and disinfect your tools. If your brushes have hair on them use a comb to help remove it and place both the combs and brush into the barbicide.

The term clean refers to the precise and well-executed cut that gives a sharp and defined appearance to the hairline and neckline.
