How do I permanently get rid of this discolouration in my bathtub? (I have hard water)
(sh.itjust.works)
I've tried scrubbing it several times with bar keepers friend soft cleanser and although it improves, it never goes away completely and it always comes back.
I think if you sprinkle a little baking soda in there that could help with some of the more stubborn stains but vinegar alone works really well. I recently cleaned all the hard water stains off my sliding glass shower door with it.
