I tried everything to un-clogg my bathroom sink drain. Vinegar and baking soda, extra long snake, Liquid Drano, etc., and nothing worked. I went to Home Depot and saw a display of Green Gobbler. It cost me $9.99, so I said, "what do I have to lose other than 10 bucks?"
So I poured the 1st pack down, waited and nothing happened for 6 hours. So then I poured the 2nd package down and left it overnight as per the instructions on the box. In the morning, my bathroom sink was completely clear, and as a result, a huge backwash of pipe junk shot up through the pipes into my shower stall. Oh boy, now my shower drain was clogged, hmm. So I used a plunger and cleared the shower drain manually. I did clear the shower drain and did not need to use my 3rd package in any way.
So in my experience, I have to say Green Gobbler worked for me and definitely saved me $200 + to hire a plumber. Thank you Green Gobbler. I do recommend this product and will definitely use it again!
Bottom Line: Yes, I would recommend this to a friend
