What can replace the green algae used for tattoos?

Some people use hand sanitizer instead of green soap, but the effect is not good. Tattooists mostly use green soap, that is, after disinfection, the tattoo parts are cleaned up relatively cleanly. No good substitute has been found yet.

Tattoos can also be written as tattoos, also known as tattoos, which insert colored needles into the bottom of the skin to create some patterns or words on the skin. That is, to pierce the skin and paint the wound to make the body have permanent patterns.
