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.
We had plastic cutting boards that covered the entire length of the counter that would become stained and dirty through the day despite being wiped down after almost every order. And since sanitization is vitally important at a restaurant, they needed to be cleaned somehow. The boards would be rinsed and wiped down every morning before use.
