23 oz. Concrete & Mortar Dissolver Spray

I used this to move cement and mortar the contracted left on my pavers. Followed directions and just sprayed it off with the jet setting wand. Unbelievable. I had thought I would be spending hours scrubbing these spots off. I never write reviews but this performs remarkably. And no harmful acid. I ordered from Zoro had it in 2 days

Works to soften dried mortar for removal and clean up.

Worked fine as advertised. Two week concrete film removed. I used with a steel brush as well.

Seem to have to use a lot of the products for it to work

It's okay. I went back to using the regular envioro that we have at the plant.

I used the entire bottle on the vinyl fence we were trying to clean. This product only removed the smallest bits of splatter after we wiped it down with a cleaning rag. The quarter size spots did not get removed at all. Did not see any sign of dissolving. Would not recommend this product.

We have purchase numerous bottles of this item to clean the concrete off two small patio brick steps. Bottomline, the first application - one bottle was able to remove a small anount of the concrete. The other bottles used on later dates removed essentially nothing.

Item leaked %26 didn't get a REFUND

First of all, the seller did not insure the bottle was closed tight and it was leaking. Secondly, it did not dissolve very well and left a bleached appearance on the material that remained.
