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.
Assuming that is an enameled tub. Try Bar Keeper's Friend (powdered not the liquid) dampen tub lightly and add a decent amount following up with a light scrubbing, letting the paste to sit for several minutes. It may need to be repeated or increased scrubbing. The slurry will probably require dampening it a bit to work it around. I find it removes iron and hard water stains. I have used toilet bowel cleaner but it is too harsh when cleaning the tub nekked! Like others have said, a water softener is the way to go. Our filtration system is currently offline waiting to be re-bed.
Since I tried the liquid soft cleanser, will the powder be enough of an improvement to warrant purchasing?
For the 3 or 4 dollars I feel it is worth having on hand regardless. I use it quite often when cleaning pots and pans where Bon Ami doesn't do the job as well.
