I suspect this is just cosmetic, but with rosacea, I can make myself worry! Dare I try a little bleach?That's a toughie. Most remedies are for polishing the copper itself.
Maybe CLR works on copper stains too. They do warn that it can pit a copper finish.
Try googling for "how to remove copper stains from clothing". A lot of those do involve bleach though.
Since boar bristles are an animal hair, maybe it reacts like wool.
For bleaching wool, I get this:
Quote:Can you use bleach on wool?Hydrogen peroxide sounds about right, since it's been used on people hair.
Wool is a natural material made from the fleece of lambs, sheep and goats. ... While ordinary chlorine bleach is suitable for lightening some natural fibers, it will damage wool. To safely bleach wool fibers, use a combination of hydrogen peroxide, washing soda and detergent.
It'll clean up blood stains too, so, Yay!
Note: "washing soda", not "baking soda".
Great idea for the hydrogen peroxide, John! I will try this first.
