Power Blue Scale Off, 32 oz

It really makes a difference!! Our pool specialist recommended this to us to use on those hard to clean spots… especially at the waterfall and cascade areas where the pumice stone couldn’t get into. It worked like a charm.

Great product, calcium off the tiles came off so easy

While this product astonished me on first use, it does not last very long. It made my scaled tile beautiful again, but it only lasted about a week. I was so excited upon first use but wish it lasted longer and actually cleaned the scale off.

Although I didn’t see it in the listing it says do not use the product in glass tiles. Since this is why I bought it , the product is useless to me.

Still working, pool tile has improved but it seems to be work in progress

This product was recommended to me by my pool maintenance company to remove calcium from my pool sides. It is working.

I used this product to remove heavy scale from the tiles in my pool. It works really well. Highly recommend!!!

I bought this after some reviews in a pool group a follow. 1) it took forever to get. I would have been ok with it had I known when I bought it, but my deliver date kept getting bushed back. I tried a few times to reach out but had difficulty using the app. 2) if you read the directions it says to spray on “dry” surface. Well… my scale issues are certainly in areas that are wet (tile line, waterfall) so that alone is difficult. 3) really didn’t get much scale off.
