Review on 🚽 Powerful Maryton Pumice Stone Pack of 4 to Eliminate Toilet Bowl Stains and Hard Water Ring by India Stack

Worked for me Removed rings from two toilets that no one else touches (we have very hard water). I used a little over half of a stick to clean both toilets, three more left so didn't wear much IMO. I'm not sure why some reviewers say it crumbles or wears out quickly. The pumice stone is said to wear out; otherwise it would mean that it is harder than the surface to be cleaned and this could damage the porcelain or other surfaces. The price seemed a bit high to me, but I would definitely recommend it. Still, getting rid of those hard water stains and rings is worth it!
