12Pack Pumice Stone for Toilet Cleaning Bowl Stick,Powerfully Cleans Hard Water Rings, Calcium Buildup & Stains, Suitable for Cleaning Toilet, Bathtubs, Kitchen Sink, Grill

It works great, all the hard water stains are gone. I tried cleaning my stoves it left minor scratches on the top so I would not recommend it on the surfaces, however for other surfaces it works great.

These are perfect for cleaning toilets and sinks. Much softer than some pumice stones, which is a good thing. No scratches.

We live on a well and have hard water. All of our toilets have a calcium ring in them. I use these to scrub off the hard water deposit. Works great, they look clean and brand new.

Man, these things take off all the crap (pun intended) in the toilet. Both my sister and I used these and our toilets are brand new again. With 5 boys in the house, these are a must. They tend to get used quickly as some stains were needing a lot of elbow grease. But it gets the stains off, not just covers them up.

If you have a stove with black iron grills I think this is the only thing that will remove the build up over time. Mine are 6 years old go in the dishwasher after big cooks but a pumice stick brought it back to as new. I only went over it lightly with one pass. I went lightly but The sticks wear down quickly so if you have a bigger job be sure to get the multi pack. I also used it on enamel finish on oven & it worked great. Although it felt very wrong to useIt did not scratch enamel. I was very careful to keep away from stainless steel. I used the pumie brand before but this worked just as good. Will be using on outdoor barbecue soon.

I don’t usually write reviews but this one is a must. This product is worth its weight in gold. I live out in the country and our water has iron in it. I had tried every product under the sun to remove the stubborn stains in my toilet bowl but nothing worked-until now. This is undoubtedly the best product for removing the iron stains. I used to be ashamed for company to come and have to use the bathroom but not anymore. I took before and after pictures and sent them to my sons and they were amazed. They actually asked me if I had replaced the toilet.Don’t hesitate to buy this product!! You will be very satisfied.

I expected far worse. My apt complex has hard water and so my toilet has been reddish brown because of the deposits. I tried the usual scrubbers and whatever, didn't work. I took one of these and erased those stains easy peasy. I wore down one brick by like 10% (it wears down as you use it) and my toilet looks like new. I have zero complaints. Just pop on a glove, grab a block, no cleaners necessary, spend a couple minutes and my toilet is now presentable.

I have tried probably every other product available to remove the calcium ring in our toilets. None worked! But then I ordered this one. Presto! The rings are gone. Gentle yet effective. I highly recommend this product. I wish I had found it sooner. Do not hesitate to order!

Took 10 plus years of scum and lime scale build up on my porcelain sink, after trying everything else!
