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.
Unfortunately we do have a water softener but for some reason, there's still buildup.
I've been seeing improvements with powdered bar keepers friend but it takes several passes and still comes back unfortunately.
