So I recently acquired a VB Brand Finest Badger brush. It is my first high quality brush and I love it. Only one problem. I can never rinse all the cream out of the tips of the bristles and they feel slimy And once they dry they are hard and crusty and clumped together (only at the tips). I have already cleaned it with diluted dish soap followed with diluted vinegar twice and have only had it for a month. This fixes the problem but I don't think I should have to clean it on a weekly/bi-weekly basis. The problem persists no matter what cream or soap I use. Does anyone know why this is happening or what to do about it?
