If you’re changing your ink colour but keeping the same needle or cartridge, you’ll need
to wash it! Before you start tattooing, you should have a cup of water on your workstation that you can dip
your needles into. Run the machine for a few seconds to ensure the needles get a good wash, then stop the
machine and wipe off any excess water with a paper towel. Make sure that there’s no lint and no remaining
water on the needle before you dip into your new colour.
