Sorry to clog the forum up with another smell thread. I have a turn back travel brush that I must have put away a little wet a few weeks ago (out of practice, haven’t done much travel lately). It’s developed a bit of a funk. I’ve soaked it in vinegar, dish soap, borax, and oxyclean. Not all at once though. I’ve left it with shaving soap in the knot overnight and it’s still got a bit of a smell. I’m worried that trying anything harsher will wreck the knot. Is there anything I’m missing? Has anyone ever tried boiling a brush? If it makes a difference is a T&H super badger knot.
