Hi, I recently purchased a butterscotch Rooney brush. This is a vintage brush, and the "butterscotch" coloring has darkened to a deep patina.
I would like to clean the knot by submerging the knot up to the handle in a solution of vinegar and water, to clean any soap build up from the base of the knot.
Has anyone done this to a brush like this before, and is there a danger that it will lighten the butterscotch patina at the knot opening?
Thanks.
