(4 pack) Drano Max Gel Drain Clog Remover, Commercial Line, 42 fl oz

I'll be honest. When I first bought this, I was very skeptical and thought it wouldn't even work. My tub drain was clogged like your nose when you're sick. Going to take a shower always resulted in the drain overflowing as well, which only added to my skepticism. When I finally bought this drain cleaner, I was pleasantly surprised to see it actually worked as advertised. Albeit it did take at least two flushes, by the end of it, my drain is no longer overflowing; I can finally take a shower without drowning my feet. 10/10

I had a clogged tub drain and it was causing the water to back up while showering. I poured about 1/4 of the bottle down the drain, let it sit for 30min before running the tub water. Clog was cleared on the first try! Very good product and have some leftover for future clogs as needed!
