Remember it's a tattoo needle that comes into contact with the skin, NOT the tube connected to the machine, YET that also has to be sterilized, and all that is is just a holder of the needle?the needle is only stainless steel and solid too
Hyperdermics only come into contact with fluids, yet the needle punctures the skin, so you can rinse out the plastic that was used as long as you use a NEW needle?.
Is it a germaphobe to want to practice safe sex too, would you rinse and use a razor from an aids patient ? and your an IDS specialist.
Uh, how many people are sharing your razor?
