Cleen Products Super Concerete Dissolver 1-Gal. Concrete & Mortar Dissolver

Bought this to help me unblock a drain with cement. I may have been asking for too much from such a product. The use should stick to cleaning instruments only.

Did not work as advertised for me

I used this to clear a shower drain trap clogged with grout. I was very happy with results. Before applying it to the shower drain pipe, I ran a quick test: I took some hardened grout that I mixed up and placed a chunk of grout in a plastic cup and then added Concrete Dissolver. The image below shows how it turns hardened grout into a green sludge. This is how I used it to clear a shower drain clogged with grout: 1) Shop vac any water and debris out of shower drain. 2) Cover shower tile to protect from spills. 3) Pour 1-2 Cups Concrete Dissolver into a disposable cup. 4) Carefully empty the cup with Concrete Dissolver into drain. 5) Wait one day and then use wet shop vac to remove the green sludge from trap. 6) Test for drainage, if necessary repeat 1) through 5) 7) Once clog has opened you can try running a drill powered snake to break up any remaining grout on walls of drain pipe and vacuum out any debris. Note: this will also remove the grout you don't want to remove, so protect your tiled shower floor from spills. I also noticed that it will remove metal finishes it left in contact for longer period. Attached Image shows Concrete Dissolver in action after several hours and 2 days.

I had to clear and old sink drain line that had been absolutely destroyed by ceramic tile mortar and wet saw residue. The line sat unused for a few years after it would no longer drain properly. I poured the Cleen Products Super Concerete Dissolver right into the line with a funnel and let it sit overnight. The next day i ran a snake into the line and was able to bust up the hardened residue and clear the blockages. Fully restored the drainage without having to cut the slab to replace a section of pipe. It save me a fortune!

This was a bust. Used it to try and remove concrete splatter from a couple doors and a metal building. It loosened a few of the specks, but didn't touch the real concrete spots. Most are less than a dime in size so it's not like they are huge spots. I don't mind to spend the money if the stuff worked, but it doesn't.

I purchased a home that had a vinyl tub insert that was relatively new but the previous owner had mixed a concrete mortar mix for the tile inside the tub and let it dry. I have no idea how long it was there but it must've been months if not years. I tried another product that soaked on it for more than 2 hours with very little change other than chipping away at it. This product started working immediately and did take some elbow grease but did the trick and the tub is like new again. Would definitely recommend. I did not take a good before picture but there were blob in the bottom of the tub that were close to 2+ inches around. You can only see small blobs in this image.
