Green Gobbler Enzyme Drain Cleaner | Controls Foul Odors & Breaks Down Grease, Paper, Fat & Oil in Sewer Lines, Septic Tanks & Grease Traps | 1 Gallon

I bought this because my upstairs drains had a strong sewer smell that wouldn’t go away, no matter what I tried. As soon as I poured this down the drain, the smell disappeared instantly. No waiting, no second tries — just immediate results. This is the only product that’s actually worked for me. Easy to use, enzyme-based, and incredibly effective. If you’re dealing with foul drain odors, don’t waste your time with anything else. This is the one.

I had a severely clogged RV black water tank. Tried all the major brands of clog removal products. One gallon of your product (allowed to sit in the tank for several days) it is fixed!!!! Clog is completely cleared. Amazing product!

Plumber reccomended enzyme drain cleaner after an emergency call out. Seems to keep kitchen sinks drains clear, but does not work on girlfriend's shower hairballs.

Works well Eliminates odor

Had a drain that had a major grease blockage, plumbing business couldn't even get it cleared, talk about having to replace drain pipe. Luckily I got it unclogged myself but it always had a smell coming from it afterwards. Tried the Green Gobbler and it's been gone ever since. Wish I knew about this product when I had the clog, might have save me money and a stained ceiling from the plumber spilling water under the sink and into the downstairs bedroom

Had a clog in my bathroom for a few weeks and tried snaking but wasnt working. Put this in and within the next 10 minutes drain was clear and water wasnt pulling up anymore!

I bought this product because it's marketed as using natural enzymes to clean and maintain pipes, which I liked in theory. The reason I titled my review “Gobble Gobble Scrum and Rum” is because—while it does work—it only works if your pipes are already fairly clean.If you’ve already got a build-up or smell, this won’t magically fix it. It’s not going to "eat the grease" or clear out years of gunk anytime soon. Realistically, if your drains are already slow or smelly, you’ll need a professional plumber first. Then, maybe use this as a maintenance product after that.Bottom line: Don’t expect miracles. It’s a slow helper, not a heavy-duty fix. Just facts.

Works well; 6 oz. direct into drain; flush with water for a few seconds. Leave in system overnight and drain is clear. Use twice monthly. Drains were cleared nicely. Avoids harsh, dangerous chemicals. For tough applications, may need to repeat several times. 1 gal. enough for whole house.
