Lenicany 6Pack Pumice Stone for Toilet Cleaning Bowl Stick,Powerfully Cleans Hard Water Rings，Calcium Buildup & Stains, Suitable for Cleaning Toilet, Bathtubs, Kitchen Sink, Grill

Really works as advertised. Make sure you get it wet first or you risk scratching it. Even if it is wet, it will make a scratching noise (don’t worry- as long as you wet it, it will not scratch the toilet). It will take a lot of elbow grease for older buildup but it took the calcium buildup off of my newer toilet (3 years old) within 15 minutes.

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!

I have never used pumice stone before. I have terrible hard water stains in my toilet. None of the commercial toilet cleaners work. I did a little research and came across the use of pumice stone for cleaning hard water stains. So I ordered this product. I wondered if it would work because it is a rectangle. No problem. The pumice stone wears down while in use and conforms to the shape of the bowl. Saturate with water and start rubbing. Wow! It removed every bit of that hard water ring. Great product.

It worked great, amazing price ( like $7 for the 6 pack), but the noise is of course horrible that it makes when using it, might not bother some people but I pushed through it. Used it on rust spots on the sink, got them off great. I even used it on a plate with rust from a metal bucket that was on it, and got it off. Highly recommend.

We bought a house that had been built in 2008. The toilets had hard water rings that were impervious to CLR, Lime Away, Scrubbing Bubbles and scotch bright pads. In less than a minute per bowl, the hard water rings were GONE. I thought we were going to have to replace the toilets. Nope, they look good as new. I sent an order to my brother who’s well produces much harder water than what we have. I would recommend this product and will use it when the hard water rings return.

Great quality, affordable price, they work well,and I cant find them in stores anywhere I use them a lot on house cleaning and tile cleaning Great durability

My oven was covered in a very thick layer of grease on the inside. I mistakenly thought it had a self cleaning feature, and had just never bothered to clean it. I thought it was too late...then did some research and it seemed that pumice stones were my best bet. Its been hard scrubbing...but these do the trick. Im not even close to finishing, but the parts that are clean look brand new. Just have to come at it 15 minutes at a time. I thought my oven was done for, but now its going to be perfectly clean once again. Would highly recommend for greasy caked on messes.

I was looking for something to gather fur/hair from the couch and carpets since I saw this trick online. It does collect fur/hair but the artificial pumice stick sheds a good bit when you take it out of the packaging and is quite rough.

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 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.
