It really, REALLY works!! (Really!)

Green Gobbler Main Line Opener And Clog Remover Seriously. It's nothing short of miraculous. I've had an ongoing problem with my master bath sink. Every 4 to 6 months it starts draining more and more slowly until it's basically unusable and we take it apart and have to clear it about a foot into the wall. We've tried several “industrial” versions of name brand drain cleaners, and a variety of cheap, zip tie looking snakes with no results whatsoever. After reading a CNET article (Best Chemical Drain Cleaners You Can Buy in 2025) I decided to try the Green Gobbler Main Line Opener And Clog Remover. Per the instructions, I poured a quarter of the bottle down the drain, waited an hour and then poured hot water in. It helped a little. The instructions said if that didn't work, to try again and let it sit overnight. Total success! Even with the water running full blast, it's draining beautifully. If you have a really stubborn clog - try it! It's worth every freaking cent! Highly, highly recommend.

Works Every Time

We live in the city, water pressure fluctuates, and we have low flush toilets in our three bathrooms. Not sure if these are reasons for slow flow, but I started using Green Gobbler Main Line a few years ago, approximately every 14 months, and it keeps everything clear. Easy to use, no mess.

We had a bad clog in the kitchen drain for over a week. Tried a couple of other products and found they didn't solve the problem. Green Gobbler solved it overnight! I should mention that I have several cats so I'm sure the clog included a lot of cat fur.
