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. close up picture of bathtub floor discolouration [https://sh.itjust.works/pictrs/image/d64d23d8-2e04-49e4-8fb2-8bfc32bba92f.jpeg]

Vinegar

Anything with hard water, just soak with vinegar.

You can even fill a ziplock bag and tie it on a faucet.

If your water is really hard, pour vinegar into that little tube in your toilet too, the jets get clogged easily and that flushes them out and prevents them from blocking up. If they are blocked, the vinegar will eventually open them up if you don’t regularly.

Obviously water softener if you don’t have one, but depending what your waters like you may have to do more.

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.
