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 would think you would need a filtration system to soften your water or it will just keep coming back.
I’ve had luck with citric acid on removing scale, but be sure to test a small part of your tub before using any new product to be sure it won’t damage the finish.
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.
