Lets say the drain is plugged. You put hot water in the sink, now the sink is full of hot water. Pour in a bottle of the pure lye and in several seconds the sink empties. You then flush with hot water for several minutes. Wouldn't believe it if I hadn't seen it myself. I keep a bottle under the bathroom sink for the occasional plug of what I can only assume is shaving cream and toothpaste buildup. Works like a dream.
