Green Gobbler Main Line Drain Opener and Clog Remover Liquid, Bleach-Free - 1 Gallon

I rent, and you can be the best tenant in the world, but that does not mean your landlord will want to fix everything. In my case, so long as the water took forever to drain, it was still technically draining, and I had to live with it. It did not matter that the previous person likely used all the drain pipes as a grease outlet, or that the bathroom sink was filled with hair and whatever else that caused it to passively seem like it always had standing water. Worse, my lease said I could not hire outside help, and so that meant I couldn't hire a plumber either. All I could do was attempt to waste money down the drain as I bought every over-the-shelf liquid and powdered declogger, or so I thought. Green Gobbler is a miracle worker. Let it sit overnight, and suddenly all your drainage problems are solved. I poured it down every drain in my house, including the drain for the washing machine. It worked perfectly, as if I had new pipes. No strong odor or fumes, meaning I could do this safely. But for your safety, try not to drip it anywhere you don't want it to go, as it will stain clothes and even leave marks on floor tiles (which I replaced) — it's that strong.

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.
