I've started to notice a little bit of soap scum build up on my Muhle Silvertip Fibre brush. I have been unable to find any specific instructions for the synthetics. The standard solution to this for a natural brush would be a washing with a shampoo or mild dish soap followed by soak in a 10:1 water and vinegar solution. Is the standard approach OK for silvertip fibre? Has anybody successfully (or unsuccessfully) tried it?
Thanks.
Thanks.
