Works great! But crumbles fast

Muy áspera. Es útil pero prefiero de otra calidad que he probado antes.

Amazing! Truly a miracle worker for those stubborn hard water stains (rust? Who knows). We tried so many things over the years and nothing worked, until we tried the miraculous Pumice stone. You have to work at it, but if you scrub for a while it is worth it! Finally I can clean my toilets and they actually look clean.

I use this for my toilet and its great but I also use for my glass top stove and clean my oven!! Game changer! I will never use chemicals again

So pleased with the results!!! I wish I had photographed a ‘before’ photo of the dingy discoloration from years of shower usage. We bought our home a few years ago and the dingy discoloration already existed. I have scrubbed and cleaned the shower floor with many things to no avail! I recently stopped in Home Depot to look for some other cleaner that might work. I saw an inexpensive pumice stick. Read the box and decided to give it a try. With firm scrubbing in a small area, I saw whitening! The pumice stick does not last long. It breaks down as you scrub with it. I went online to Amazon and ordered this set of six. I used 1 and 1/2 more sticks to get the shower floor to where I was satisfied with the level of whiteness. Since my shower floor had a pattern and tiny groves, it was harder for the pumice to reach down in those tiny patterned groves. I used a scrub brush and scrubbed all the residual pumice that was powder now, into those grooves. That did the job! This job did not take too long but I did use all my strength to scrub. Just read what pumice can be used for sonce it is abrasive.

This stone works miracles! The price is almost free. If you don’t buy it ur a fool

These sticks are much softer than most pumice stones, they erode quickly, especially when submerged in water while cleaning. But theyre a good value, so theyre fine for quick uses. Get a harder stone for tougher jobs.

We recently moved into a house and the rarely used guest bathroom toilet had a calcified ring just above the water level. I tried 3 different toilet bowl cleaners. Nothing would remove it completely until this arrived. My niece, who worked a summer job for a cleaning company, told me about it. It is man-made pumice stone, not natural and not as hard as natural. Keep it wet while you scrub and it will not scratch the porcelain.

I clean houses. We have highly mineralized water so I use these to remove calcium deposits from tubs and toilets. They require elbow grease but will remove the deposits without damaging the porcelain. Don’t use on metal though. Will scratch up fixtures.

I’ve tried a lot of at home methods to try and get rid of the hard water build up but nothing really worked. Finally decided to give this a try and it worked like magic. It takes a bit of arm grease if your build up is thick but it’s so worth it - got my toilet looking brand new!
