Kleer Drain Instant Drain Opener is a super-powerful compressed-air drain opener. Kleer Drain utilizes efficient air-burst technology to quickly clear the toughest clogs and obstructions in drains for showers, bathtubs, sink, toilets and exterior drains, and -- unlike other drain cleaning products -- it is environmentally safe.

Once your Kleer Drain is loaded with a CO2 cartridge, press firmly down on the handle. A needle punctures the CO2 cartridge sending a powerful burst of air through the chamber and into the drain, instantly unclogging it. "Power Disks" are used for severe clogs that may be some distance down the drain pipe.
