Smart 'n Easy Efflorescence Remover - Heavy Duty Professional Strength Formula - Removes The Toughest Salt, Calcium, and Magnesium Deposits from Concrete, Brick, Stucco, Pavers, & More - 1 Gallon

We had our hot tub sitting on an 8' x 8' pad for 16 years. After removing the hot tub and the pad, a great deal of efflorescence could be seen. The Smart 'n Easy Efflorescence Remover is gentle, yet it took about a dozen or so applications to remove most of the efflorescence. HELPFUL HINT: Do not use the product on a very hot day or in bright direct sunshine. The product evaporates too quickly and does not have enough time to work. Cloudy days or late afternoon work best.

Absolutely did not work as I expected. Wish I could return. Very disappointed

It works so well have to purchase more because I now notice other areas need to be treated.

This really did work - removing the efflorescence. It did take a second coat on some of the pavers, but it did make them look so much better.

Had some nasty efflorescence spots that were on my newly installed porch all winter. After applying the solution 3 times and power washing with an electric power washer it finally came off. Looks great. The 3 stars are because I had to do it three times. If it came off after the first application it would have been 5. I also waited 30 minutes in between each wash and application as the directions said.

Removed a lot of efflorescence. Did not remove all efflorescence as stated.Very easy to use.It is somewhat expensive but is way way more effective than CLR type cleaners. I did expect better results although the results were very good. In fairness, my efflorescence is 40 years in the making though it did say it removed years of efflorescence.If you want to remove efflorescence this is a good choice. If you want like new results, buy new pavers.

I found this product easy to find.The instructions were easy to follow. It worked just as advertised. Highly recommend
