The best way to clean a squeegee is to
simply wipe the ink off the blade and handle using paper towel, or
scrap paper, then place aside to let the squeegee dry.
There is no need to wash them with
water or any liquid cleaners.
Wiping them will get almost all the wet ink off the handle and
blade.
Then after the ink is dry it will peel
straight off the blade.
If the ink build up is too heavy on
the wood then you can scrape/ peel it off, but if you wipe it off
with paper after use this wont be a problem.
Ink colour on the squeegee doesn't
matter - they are never going to be kept perfectly clean.
