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

I’ve tried several different kinds without success. I sprayed this stuff onto old red brick with significant effervescence, let it sit for 30 minutes and washed off with a pressure washer, no scrubbing. It did a great job! Brick looks much better. I’m going to do the rest of the house!

This Did Not work on my Red Bricks to remove Calcium deposits at all. In fact it made them Whiter than before use I would Not buy again We let it sit 30 minutes. And used high power Pressure Washer. No Help at all and was Expensive compared to other products. A Complete waste if money and time

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 have a shower with pebble stone tile that developed efflorescence in many places. I followed the instructions and performed a test on one section. The test results were great. Results of the overall application: Most of the efflorescence is gone. What future customers need to be aware of is that the product discolored the grout in some areas while other areas were not affected. I suspect this might be because the area I treated is very large and possibly more than one bag of grout was used when the tile was installed. I used a scrub brush attachment on my drill to get some of the orange residue off. I hope the discoloration can eventually be removed, but it is not going to be easy or quick. Lesson I learned: treat small areas at a time.

Product as advertised. Haven't got to use the product yet.

Total Waste of Money! Doesn't even slightly work. All the good things you read aren't true. Used PREDATOR 4400 PSI, 4.2 GPM, 13 HP (420cc) Commercial-Duty Pressure Washer, CARB with this product. Don't waste your money on this product. If I could give zero stars I would.

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.

Second time buying this. It worked great the last times I needed to clean residue from my brick steps and aggregate driveway. Easy to use.
