I just tried cleaning mine with a pointed q-tip and makeup remover. Some of them have a little screw on the blade and you could take that off and clean it.
I clean it with a q-tip too. But I don't use makeup removers. I just clean it with a q-tip, use a new one when the q-tip is all stained, and do this until the q-tip does not have any stains on it anymore.
