20 Pieces Pumice Stones for Cleaning - Pumice Scouring Pad, Stick Cleaner for Removing Toilet Bowl Ring, Bath, Household, Kitchen, Pool, 5.9 x 1.4 x 0.9 Inch(Gray)

Super durable, tough, works great, great value for the money, no soft as it shouldn’t be,

Got 20 of these for just a few dollars more than the price of one at our local pool store. Works to get iron water stains off of the grout on pool tiles, which comes from our irrigation well. Good for other household uses as well.

Don't be fooled into buying a brand name of this type of product. These work great and the price is good, too.

You get quite a lot of the stones; however, they are not as dense as the ones I bought in localStores. These seem to break down more quickly.

I used to always buy "Pumie" brand sticks that cost $5/$6 for one. These are the same exact product, only in bulk and for a fraction of the cost! This is one Amazon find I always share with my friends! This one is a no brainer. Cleans porcelain toilet bowl hard water rings in a jiffy! Yay!

Like the headline says, these pumice stock blocks just work. Not sure what other reviewers were talking about in saying that they didn't work. I have a salt water pool and noticed calcium build-up in certain spots and tried a different pumice stone product that was just ok. These blocks were just what he doctor ordered in getting the calcium off! Will you go go through a few of these as you clean? Yes, without question - especially if you're using them to clean tile that is also really close to the water (e.g., water line in the spa). But the thing is that they work - you just need to take the time to do a few passes over the same area to get all of the build-up off. Remember, these deposits form in layers, so you take off a layer or so with each pass. I used a total of 4 pumice stone blocks to get rid of the calcium spots on the water line tile in my 15x30 pool as well as along the water tile line in my spa. They worked exactly as advertised and removed the calcium without damaging the tile - and I have glass tile!One quick note, please don't follow the Youtubers who tell you to use a paint/rust remover disc with a cordless drill. Yes, this works but you end up thoroughly damaging and scratching your pool tile - use these pumice stone blocks instead. Yes, it will take some time (in my case, nearly 90 minutes of good old fashioned elbow grease) but you're in the pool, so it's a win-win!For what you pay, you get plenty of stones - I ordered 2 packs to have 40 blocks. If you clean the calcium build-up as soon as you see it, you will definitely use less of these stones over time.Highly recommend these for anyone with a pool!

We had what we thought were permanent stains on our toilets due to hard water. I was in the process of pricing new toilets, and we decided to give these a try. The toilets literally look brand new, miracle product.

I have a oven that I was unable to scrub inside off. I used so many things and nothing worked. This items worked so good. Just scrubbed the dirt away! Better than any chemical. And non toxic, kids can be in the house while cleaning oven.
