I had a persistent biofilm that was clogging up my bathroom sink. Several rounds of baking soda and vinegar + plunger got rid of some of it, but the drain was still sluggish. I used half the Green Gobbler bottle, per the instructions for lighter clogs since the vinegar and baking soda had already taken care of some of it. I left it in over night, and in the morning, the drain ran clean. I used the remaining bottle and a half in my two-pack to do maintenance clog prevention on my shower and three other sink drains. All running great. And I feel confident that Green Gobbler is safe on my pipes. Also love that it doesn't have a strong odor. Read more

I’ve dealt with stubborn drain clogs more times than I care to admit, so I grabbed this hoping it would do a better job than the usual stuff on the shelf — and it absolutely has. Right from the first use, it tackled buildup that had been slowing down water for weeks, and I didn’t have to pour half the bottle to get results. One of the biggest wins for me is how versatile it is. I’ve used it in the kitchen sink to cut through grease and food residue, in the bathroom shower to dissolve hair clogs, and even in the toilet when things were draining slower than usual. In every case, I just followed the directions, let it sit, and then flushed with hot water — and the water flowed like new by the end. It doesn’t leave behind that awful chemical smell that some cleaners have, which is a relief, and I don’t worry as much about fumes when I’m working in smaller spaces. Another thing I like is that it’s labeled safe for both pipes and septic systems. I’ve used products in the past that claim to clear clogs but end up worrying if they're too harsh on my plumbing. With this one, I feel comfortable using it around the house because it’s powerful without feeling dangerous to the system as a whole. Read more

TLDR - solved a 6 month issue overnight. Our ancient apartment has a shower that doesn’t drain and usually ensures we are in shin deep water by the end of the shower. It also meant anything like hair from shaving never made it down the drain and formed a nasty ring around our tub unless I waited for the water to drain and then washed the tub before it dried. Pretty stupid esp for Boston rent prices. The clog was beyond the reach of the drain snake I bought but bits were coming up ONLY when I went down the overflow - old tubs have a grate under the drain. I poured a third of the bottle into the overflow and the rest into the drain, let it sit about 12 hours, flushed with a bowl of hot water, and wow. Tested the shower and ZERO water accumulating. THE DRAIN ACTUALLY DRAINS! So yeah, my tip is to try the overflow if your tub is 9000 years old like mine. Read more

My bathroom tub was slow to drain for a long time. I would try Drano commercial line and it seemed to clear the drain for a week and then back to slow draining. I even tried BioClean but still not draining well. So I found this product. And what a game changer! I put 1 bottle in the drain and waited for 1 hour and it cleared the drain a lot faster than the other products I used. I still feel like it wasn't totally unclogged so I used a 2nd bottle and waited about 6 hours. And WOW! The water is now draining faster than it has in years! I highly recommend this product!

I've had Green Gobbler work in the past so that's why I give it a three. I don't know why recently it no longer works in my shower. I hate to say that I'm going to have to resort to Draino for super intense clogs. Maybe it will work if your issue is minor. Read more

This worked perfect for me. One bottle each in a duo sink cleared the clog within a few hours. Read more

Used Green Gobbler Ultra Concentrated to clear a slow bathroom drain and it worked quickly with minimal effort. The instructions were easy to follow and the drain has been running smoothly since. Took off one star only because the bottle is small for the price, but overall it’s effective and worth having on hand. Read more
