Drano Dual Force Liquid Clog Remover 17 oz.

Safe for garbage disposals, bathroom, kitchen and other drains like laundry sinks. After you pour Drano Dual-Force foamer into a drain, the two ingredients combine to form a powerful clog buster. The foaming action fills the pipe and thoroughly clears its walls, dissolving gunk. A blast of hot water flushes away what’s left of the clog.
