So I have very hard water and I had to install one of those whole house water softener/filters. The kind that you have to add salt pellets to. Now once I installed it I had no problems with my water at all. At some point within the last couple of days, the circuit was tripped and the filter cut off. I didn't realize it and I did some laundry and shaved with my badger brush. The water stained a couple of my undershirts and my brush. I am not worried about my shirts but I really like my brush. Is there a way to take the stain out of the badger hair? Thanks for any tips.
