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.

had a slow kitchen sink drain and with 16oz of treatment for 1/2hr ot opened the drain up. I followed up with another 16oz let it sit overnight just for added precaution and my sink is totally clear now. Able to fill the sink and pull the plug with a couple of gallons of water and it drains fast.

It really works!
We had a main line blockade(ancient plumbing). I tried other clog removers, no luck. I tried a toilet snake, nope didn't help. Last try was this stuff before I called Roto-Rooter guy or plumber. This is like about 20 bucks but completely worth it. I definitely recommend it.
