Used this to unclog sewer trap at junction of where sewer line leaving my building meets main town sewer line under the road surface…poured in half quart at the trap and left overnight, by morning…voila!…problem solved…..tried other products (Home depot etc.) that didn’t make a dent in the problem. Best $21 ish I’ve spent…

This is my first review on a product and this deserves 10 stars! My kitchen sink was very slow draining and knew it was only a matter of time before it was 100% plugged. I had tried several other methods and products and nothing helped. I read the reviews and decided to try. Used 2 cups and poured slowly and waited. I did put a bowl over the drain b/c I could see and smell fumes. I waited 20 min., everything drained, but when I started to use the faucet, it started to fill up again. I then used a plunger for 5 seconds and the clog came loose. I'm so relieved it works!!!

This stuff works like no other. Our shower drain, 25 years after construction, was full of hair and soap. One or two prescribed doses does the trick. This is after years of the store-bought drain cleaners and online lye-based cleaners just muddled along. Those lye products can loosen the debris, but just enough to slow the drain or, worse, harden into a solid clog.This sulfuric acid breaks through without clogging. (Though instructions and other online advice do caution severely, don't follow other products with this strong acid.) Follow every caution and warning in the instructions and online advice. Google sulfuric acid in drains. There are some disasters out there -- this is the real thing.Buy the heavy black pvc coated, chemical resistant, elbow length gloves, and use good eye protection. If it will eat through what's in your drain, it will eat through your skin and eyes. It sort-of "explodes" up out of the drain when it interacts with all the crud you're trying to get rid of, so stand back. And use a fan and exhaust fan so you don't breathe the toxic fumes.But it works!! Nothing works like this, and I think we tried them all before.If you are competent to handle dangerous sulfuric acid, you'll be pleased with how well this stuff works....ADDING THIS IMPORTANT SAFETY CAUTION ALMOST A YEAR LATER....Just to reinforce the safety cautions I see in the few negative reviews here, and on google regarding sulfuric acid in drains .... If you have used lye-based products and consider using this acid, be absolutely sure you have washed all of the lye out of your drain multiple times before using even a tiny dose of the acid. If there is still lye clogged in there (apparently this happens commonly, based on reviews and other online disaster stories), the acid will explode violently and dangerously up out of your drain with amazing force. You'll be cleaning your walls and ceiling for hours, if it doesn't get in your eyes and send you to the emergency room. The company seems very responsible to warn us in their instructions on the bottle. I'm just saying, please take these cautionary tales seriously.
