Bests & Worsts Reviews from Amazon

I had a sink in my master bath that was barely draining. It was driving me CRAZY. So I went looking for something that was not as corrosive as Drano and I found this. I read a bunch of the reviews and decided to give it a try. I slowly poured in half the bottle, then waited 45 minutes, then poured a full kettle of boiling water slowly down the drain. I went to bed. When I woke up, the drain is completely clear. Not just better than it was, but good as new. I highly recommend. Plus - there's no fumes!
