Questions & Answers

Are you able to use it Are glass tiles going to be damaged by this?

I appreciate your interest in our services. We always recommend doing a scratch test before we begin the full cleaning process, so we can make sure that we won't scratch your particular tiles. There are many types of porcelain and glass tiles for pools. It is an all natural volcanic product that can be used on almost all tiles in a pool.

Can it be used Do the tiles scratch when it lands on them?

A bit of glass tile is scratched by it.

Would anyone have any information about whether this could be used on gunite pool surfaces?

Your pressure will depend on how much you apply. Even if you are trying to remove a small stain, it will probably do the job, but some plaster should also be removed. A pool plaster, especially old pool plaster, is brittle, so you need to be gentle when removing it. Moreover, there is the matter of size of the stone to consider. The makers did not consider how it would work when they made it. To be more specific, I have difficulty working with the stone because it is too big. For me to be able to use it, I had to break mine into tiny pieces. I wish you the best of

Hello there, You can use the product around the grout as well because it is designed for tile and as such can be used for tile
5/5

If the grout is loose, it may be affected by scrubbing it even more.

Definitely recommended for heavy duty work
5/5

It was a bit skeptical when I saw the PRO size and other blocks I had looked at and wondered if it was a Nevertheless, I took the plunge into the unknown anyway, thinking I would check everything out once it arrived and if it seemed "cheap" or "less than" I would return it right away. The weight of it when it arrived was a clue that it was dense and worth opening and testing. We have a lot of hard scale to deal with in Arizona and so far it's held up very well in durability but most importantly, it's getting rid of The block is definitely worth the money, especially when there is a lot of scale to grind.

It is the only pumice stone I've found that can work on my calcium deposits in my pool
5/5

This is the first product that works and doesn't disintegrate after a few tiles that has pulled calcium from my pool surround tiles. I have searched for over 10 years for a product that worked and did not disintegrate after a few tiles. There are about half of the pumice stones left in my pool, and I am about half-way through cleaning it. What a wonderful thing to hear. * It requires a significant amount of pressure in order to work properly. In order to get sufficient force, I usually have to use both hands and brace my legs against something. Trying to do some dozen tiles a day can be tiring, so I try to do this in small increments. It makes me sore in my arms and shoulders when I use them too much. It is normal for me not to write Amazon product reviews, however this purchase has been so successful that it is necessary to share it.

It takes a lot more energy to transport this heavier stone
5/5

Upon purchasing my home in Scottsdale, I discovered that two in-depth tiles surrounding my pool had calcium deposits build up over a period of several years. it was expensive, I paid the pool cleaners to blast the most visible parts. I used pumice to clean off the spillovers after they disintegrated too quickly with the first one I bought. The most I was able to do was There are about a quarter of a million tiles on the first stone, and half of that amount on the second stone. Since this stone is much heavier and more durable, I was able to complete the whole Despite being heavier, it still makes the forearm work more, but it lasts a long time. While cleaning the tile, be sure to keep it and the tile wet and cover a wide area before you go back over one spot rather than overworking one location since the calcium softens after removing the outer crust.

This is an excellent product
3/5

I highly recommend it. To efficiently remove calcium build up on waterline tiles, this extra large piece of pumice works well. It took me 3 years to remove the buildup from my tiles. I also have a wall made of 2" tile that juts out over the waterfall. So I have 230 tiles 6" on waterline. Over the course of four separate treatments, I used the pumice stone about one time per session. Each interval of 5 hours should be used for cleaning off the buildup. There is no white buildup on the surface anymore, it looks like new! We used up about 3/4 of the stone as a result of our effort. With the stone's size, it is easy to hold and manipulate in various angles so that you can use it on various surfaces and in various edges. Just ordered a new stone so that the next time I can do it once a year, to reduce the amount of time and effort it takes.

Don't let your elbows stop you! A new home we moved into had a pool with a ton of calcium built up on the tiles
5/5

It is impossible to remove the calcium build-up with elbow grease! I was unable to get rid of the fine layer that can only be seen if the tiles are dry, even though I scrubbed and scrubbed and scrubbed. My recommendation is not to do that. A better way would be appreciated if anyone can suggest one I'd like to hear what you have to say.

Those results are awesome
3/5

A long time ago Amazon should have ordered this, as it did not work for me when I tried it at a pool store. I am so glad I tried again with a stronger product after my friends suggested it.

The pumice was fake and broke when it arrived
4/5

It crumbled and made a mess when I tried putting it in the pool. There are fewer cracks than in When it comes into contact with water, it dissolves. Although my water chemistry is perfect, I don't like it. There is only one positive thing about it it floats, so it will be removed by my skimmer. Edit this paragraph. I was wrong to think this would be so bad. It appears that this stone has been deposited around the pool's top. There will be a time delay between now and when it is filtered.
