Customer Reviews for KLEEN KRETE 32 oz. Multipurpose Concrete Remover and Dissolver Spray Bottle

Rating provided by a verified purchaser

It worked well on small patches of dry concrete but not on anything larger than the size of a quarter.

Our vehicle had dried on concrete down the passenger side from a highway project during a trip in 2016 and i have tried every imaginable internet hack to remove it. Finally, four years later, i through all caution to the wind and used the Kleen Krete product which stated it could be used "safely" on a vehicle. I tried the 30 minute application but only had marginal success. The overnight application worked amazing and using my power washer i removed 99% of the concrete. A few spots were left that required another application. There was no damage to the finish and after applying a wax finish it looks like it is brand new. Thanks Kleen Krete for a product that works.

This product actually worked. I sprayed on the hard cement that I couldn't remove, left on for several hours (only because I forgot about it). Used a scraper and the cement came off, it had softened. Really good product!

This product doesn’t work to take off the cement of vehicles.

Product meets expectations and works as advertised. I used to remove concrete slurry on exterior of both right side doors of my truck. Removed the concrete without paint damage.

Barely did anything. Would not recommend

Our contractor spilled concrete on our new stone pavers while installing wooden posts for a patio cover. He cleaned what he could but it wasnt enough for Hubby.. I found this product after reading several reviews and it did not disappoint. We sprayed on left for 30 mins and scrubbed with a brush after the first rinse it had removed alot of the spilled concrete! We are impressed!

This product took off very small splashes of concrete but didn’t really work on the big splashes.

Unfortunately, this product did not come close to doing what we had hoped - removing concrete/stucco splatters from glass. Further, now we have a very large container of product to properly dispose of. Oh well. Life still is good . . .

Excellent product. Effectively removed dried cement on pavers

Was able to remove all the dried stucco splatter from my windows. Some spots required 2 -3 applications but they all came off.

I had high hopes, but for me it did not perform as described

Works as the label says. Will definitely use in the future to maintain all of my concrete tools because it easily causes cement to wash away from surfaces no scrubbing. Wish they carried it at my home depot store

It removed most of the concrete but not all of it.

Did not really work.

The product work well, but it left a film on brick which was added work.

Had a bag of cement break open in the back of my pickup and it got all over the back of my truck. Used this product to take it off after it had already dried and then washed the truck and it came out great. Definitely would recommend it!

This product did not work for me. I had viewed a couple of videos on this and similar products, and decided to try it. I have a 40 year old wheelbarrow that was covered with old concrete and mortar over the years. I had to replace the wood so decided to clean up the bed and repaint. I spent a couple hours a day for a week on this, and had very limited success. I tried various settling times (5 minutes to thirty minutes) on the spray prior to wiping it off.. I had chipped off a lot of the cement before I started spraying to get it down to 1/4 inch thickness max prior to spraying. I had more success beating it with a hammer to try and get it off. A couple things; (1) wear a mask-this stuff is toxic and will sent you in a coughing fit (2) Do the spraying in cool weather. I had more success in 60 degrees than 80 degrees. I will reassemble the unit without painting it.

I had concrete on my new truck and it loosened it up and I just wiped away. Amazing stuff.

It’s not a miracle but it works.

I had some thick concrete over few bricks . I had to apply it 3 times in order to get rid of all the concrete but it also took the color off
