It is highly recommended regardless of the type of cartridge system used, that a re-usable grip is cleaned with soap and water and then placed into an ultrasonic cleaner before being sterilized in an autoclave after each client. If an autoclave is not accessible or the manufacturer instruction prohibit this, then the cartridge system must have manufacturer proof of having a backflow preventer to be cleaned and disinfected, instead of sterilized between uses. For those using a cartridge system with a backflow preventer, the grip and machine must be: Covered well with disposable plastic cover
The plastic cover must be securely attached to the unit with tape
The plastic cover and tape must be discarded between clients
The re-usable grip and machine must be cleaned and then disinfected with a Tuberculocidal or Mycobactericidal disinfectant after each use.
