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.
CLR usually works quite well for stuff like this. It's a spray cleaner. I think it stands for Calcium, Lime, Rust remover.
Just a word of warning on this - I’ve had CLR ruin countertops and sinks by accidentally leaving it in contact with them for a long time, make sure you’re diligent about wiping up rings from containers and any drips - learn from my expensive mistakes!
Also test it in a hidden spot first to make sure it doesn’t dull the finish or something.
Edit: IMHO give the vinegar suggestion a go first, much less caustic
I use CLR too (lots of tannin in my well water). Requires some elbow grease but works pretty good
