This is what happens when you put a piercing gun in an autoclave.
If you can’t autoclave something, it shouldn’t be used for a piercing. This goes for everything. Needles, clamps, jewellery, everything.
Autoclaves kill off bacteria and sterilise the equipment using UV rays, meaning they come out sterile. Hospitals use these for their scalpels and clamps, piercers use them for their needles and clamps.
If it can’t be autoclaved, it shouldn’t be used in the actual creation of a piercing.
This is one of your best posts/words of wisdom.
