Customer Reviews for Mean Klean 1 gal. Concrete and Mortar Dissolver

Didn’t work ! Even though I followed all the instructions

Good stuff. Not only for concrete but also hard water deposits left on sinks tubs and anything else. Also cleans copper like new.

I had an overlay of concrete on some brick pavers that wouldn't come off. This product dissolved it to a sludge which removed easily with a garden hose. Great product!

The maker stated that the product would soften the concrete or mortar and it would rinse away with water.It did not.

Works well for my needs

The bathroom sink drain was "spiked" by a previous owner of the house. They had grouted the tile and cleaned their tools in the sink with insufficient water. The grout had hardened and the drain barely worked. After cleaning out the water in the trap, I dosed the drain with a few ounces of Mean Klean every hour until the bottle was used up. The next day the drain flowed as good as new. A unique product for an uncommon problem.

Great product

Didn’t work at all

It was thick concrete with 2 large stones imbedded so I had to use the pick also.Mean green definitely helploosened enough to disinegrate.

This product did not even come close to dissolving the concrete left on the back of some tiles I wanted to reuse. I am returning it and would not recommend

Used this to remove concrete from our car. A cement truck spilled concrete in the road. The concrete was slung down the side of the car from the tires going through it. This product worked great for removing it from the car. Used it early in the morning before it got too hot so it would not dry so fast.

This stuff is totally worthless! I followed the directions and I might as well have sprayed water on it. Save your money, don’t buy this stuff! It doesn’t work at all. Total Junk!!

Did a great job on removing concrete splashed on siding and Windows. Requires many applications to remove thicker drops but patience is the answer.

Magnificent product! I was truly pleased that a product actually made the cut by living up to the products documented claim to fame. Outstanding results and I recommend to anyone where grout has been applied to an etched glass picture.

Did not dissolve the cement at all. Fizzed and thats about that. Product not described correctly.

I used it to clear a shower drain trap that was filled with hard mortar, it took awhile but it softened it up to where I could clear it with a sewer snake.

Had dried cement on side of my truck and it took it off after several tries.

It was good to find something that helped avoid having to redo plumbing. Mean Klein did a great job. Very satisfied with the product.

I used the product to remove grey grout stains from black porcelain exterior tile, on my front porch. The product worked perfectly. You have to soak the affected area with product for 30 minutes and then wash off with jet spray setting on hose sprayer.

Helped with mortar in shower drain line without cutting out clog

Found that this product quickly dissolves new dried-on concrete. It has trouble with older dry remains. It takes some scrubbing.

did not work as good as it was shown todo on youtubehad to repeat the process about 10 times and still not all of it came offended up using a screwdriver and hammer to get the rest off
