Autoclaving is the only acceptable method of tool sterilization period. This includes Hospitals, Dentists, and Tattoo Shops. All reusable tools such as piercing equipment, tattoo tubes, Nalgene rinse bottles, ect. will be sterilized by a steam autoclave. At Labyrinth Tattoos, we test our autoclave on a regular basis by doing a spore test provided by B-Safe/Germiphene infection control. All certificates are kept in a binder and can be viewed by our clients.
