We renovated our guest bathroom a year ago but we didn’t know we had a slow drain until we had guests a few months ago. Long story short I tried everything and quickly realized we had hardened grout and thin set mortar in the drain. Purchased this product and poured half a cup at first. Didn’t dilute just straight up poured it down the drain. Used a hanger and a hand held auger to breakdown the material in the drain. I let the solution sit for four days and would use a hanger to try and breakdown further every couple of days. On the fourth day I rented a wet/dry vacuum. Sucked out the old solution. Poured new solution. Let it sit for 30 minutes and used a pressure washer as instructed. Repeated this six or seven times until an explosion of thin set and grout came out of the drain. On the last round I used the pressure washer and sucked out debris from the drain. Poured hot water and bravely turned on the shower. Voila! No overflow. No blockage. This product saved us thousand of dollars. I almost gave up but told myself to be patient. Some tips. It will stain your tiles. We have dark gray hexagon tiles with black grout. I didn’t prep the are they first time and got a little splatter on the grout. It did come off but only bc I cleaned it off right away. When you use the pressure washer stuff will come back up. I am so happy I prepped the shower floor. The mess was manageable bc of the layers of protective material. You can’t just pour and wish for the best. You need above mentioned tools. I would also like to add I’m handy but don’t know much about plumbing. I was determined to do this on my own. I was also happy to be away from two toddlers to tackler this :-) Good luck, hope above was helpful. Review: This Product is Magical - This product literally saved me over $2K. Roto Rooters gave me an estimate of $2,500 to unclog the grout from my Bathroom shower pipes and off course I told them to get TF out of my house. I paid this idiot who claimed to have experience in tiling showers, not only was the job messed up, this idiot sent Grout down the drain so off course it clogged up. I spent hours trying to snake it through. I used two commercial snakes borrowed from The College maintenance down the street from my house. Why two? The first one broke, the tip on the front of the snake literally couldn’t do the job, second snake was just not doing it either. Finally, I looked up other options online, and I saw this product. Heck, I had nothing to lose. I definitely wasn’t going to spend $2K to do it. This product worked amazing, used as instructed plus more, I kinda cheated and just sent about two cups down the drain. And let it sit and came back about two hours later and ran the hot water. Like magic, I just heard the toilet water drain out as if something just broke through the pipes. That grout was dissolved and now my drains are clear. This product is amazing and wish I could give it 10 stars!!! 🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟 ## Features - Causes serious eye irritation. - Harmful if swallowed. - Easy to use: Bio-degradable, Non- Acid formula - just mix with warm water! - Immediate Results: Quick & Proven!
