Drano Aerosol Plunger
Drano Aerosol Plunger was developed in the late 1960s, intended as a safer product that would be kinder environmentally. It was basically just a can of CFC propellant, the best-known brand of which was Freon. After Earth Day in 1970, there came increasing pressure to eliminate CFC propellants. Drackett used cheaper propellants, a blend of propane and butane, in all its other products. However, the propellant mix created a fire hazard.
The product was problematic. The forceful propellant required most consumers use both hands to control the can, plus another hand or two to hold a rag over the drain vent to contain the pressure. The pressure sometimes knocked apart poor plumbing without blasting free the clog. Consumers who ignored instructions and attempted to use chemical drain openers first could be chemically burned from blow-back.
Liquid Drano was introduced in response to Clorox’s purchase of Liquid-Plumr in 1969. Originally, it was simply a liquid lye. In the late 1970s, the product was reformulated as a combination of liquid lye and sodium hypochlorite. Sodium hypochlorite is used in low (5%) concentration as laundry bleach and in higher concentrations as a swimming pool disinfectant.
Liquid Drano is marketed in several forms, including Drano Liquid Clog Remover, Drano Max Build-Up Remover, and Drano Dual-Force Foamer Clog Remover. All are variations on the basic Liquid Drano formula.
Drano Foamer first started out a powder similar to Crystal Drano in which water had to be added. This was the first-ever foaming pipe snake product. This caused Liquid-Plumr to launch Liquid-Plumr: Foaming Pipe Snake, which is a 2-in-1 liquid.
Many years later, the makers of Drano decided to reimagine Drano Foamer as a 2 in 1 liquid known as the Dual Force Foamer.
The Drano Snake Plus Drain Cleaning Kit combines a mechanical snake for loosening clogs, with yet another gel-variation on the Liquid Drano formula.
