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!

I had a slow draining sink and I had a plumber hit it with 4000 PSI and it would not budge. I poured 15 ounces of this every 15 minutes for 45 minutes (for a total of 4 pours) and a total of 60 ounces. During the third pour, it sounded a little different and I had a glimmer of hope. Now the drain runs like a river. The concrete block in my drain is gone. Word of caution - You may only want to use it if you know your drains are entirely PVC. I can't vouch for how it reacts with any other types of drains.

Can't be delivered to my address. Then why sell it. Long time user of Amazon, used to love it, now, not so much.

I tried it for a day than three days then finally -I’ve left it in for a week in a concrete blocked to the trap and I get a little sand that washes up+each time . it’s very slow going. I switched to Croc Crete which is much more expensive – 5X -but it’s not much better.. It’s now been three months and I’m about halfway through the trap. I’m going to re-order this stuff after the Croc Crete is used up.

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 put floor leveling concrete in my furnace room floor, unfortunately I didn’t cover my floor drain very well and some of the concrete went into my floor drain trap. I poured some of this product down the drain and let it sit for one day, I could see a little bit of the product was going through the trap so, I vacuumed that out and poured more and waited another day, it finally opened up. This beats paying &1,000.00 to have a company come in and jack hammer the floor and replace the valve, I would recommend this product.

The first delivery time wasn’t met and I needed to send multiple notes to obtain updates. It took over 3 weeks to obtain product.Product does work in removing cement that’s why I wanted to order a larger size of this product. But you will need to wait and be proactive to obtain shipment updates.

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.
