Momentum Brands Pumice Cleaning Stone with Handle Toilet Bowl Cleaner Hard Water Ring Remover for Bath/Pool/Kitchen/Household Cleaning 4 Pack

Wow this works amazingly well! I didn't really have hard water stains. But I accidentally cleaned my toilet bowl with the wrong type of sponge and it caused oxidation. And had a lot of gray marks I just could not get out with bleach and other things. But this worked in less than 5 minutes. Make sure to dunk it in water first. Then just scrub away it honestly does not take too much elbow grease but I also didn't have a lot of dirt or anything on my toilet bowl. But it did leave it absolutely shining and looking like brand new. I wish I took before and after photos. This honestly worked so well and so easily.

Realmente es un excelente producto, quita perfectamente el sarro de los baños y sin mucho esfuerzo. Había probado de todo y con nada había podido quitarle el sarro a mi baño y ésta piedra lo hizo fácilmente. El único inconveniente es que se desgasta muy rápido, pero aun así lo volveré a comprar.

Have tried almost everything over the years to remove the hard water rings in my toilets and wasted a lot of money in the process as none of them worked very well. Read the reviews here and elsewhere about these pumice stones and I'll admit, I was nervous that I might scratch the porcelain but as long as you keep the stone wet and press/move the stone just hard enough to remove the ring, it does the job very quickly and efficiently and no scratching. It took me all of 5-10 minutes and toilet looks brand new. Barely wore down any of the one stone I used.

Esa madre sirve chingón, quita el sarro de los vidrios (lo más castroso en el baño) y del W.C. Es de esperarse que se desgaste muy rápido por el tipo de material así que la recomendación es usarlo en lo crítico primero, luego en lo importante y, finalmente, en los generales.

I have tried EVERYTHING to get rid of ring in the toilets, mainly caused by well water - it's just a build up and no matter how clean your toilets are, the ring makes them look like they haven't been cleaned. I tried these and it did a beautiful job!!! I am so happy!!! My rings are completely gone! No scratching and worked well. You do have to put some elboy grease into it, if your toilet has build up, but now that I've scrubbed the ring away, it's quick and easy to maintain.
