American brand of drain cleaner that is manufactured by S. The release of hydrogen gas stirs the mixture and improves the interaction between the lye and the drano clogging the drain. It’s possible that pressure may build up inside the pipe, causing the hot, caustic solution to spurt out of the drain. This removes hydrogen, which poses a fire and explosion hazard and produces ammonia, which is also capable of decomposing organic material, albeit less aggressively than lye.
Crystal Drano was invented in 1923 by Harry Drackett. From the 1960s into the 1980s, Drackett advertised Once in every week, Drano in every drain. Bristol-Myers bought the Drackett Company in 1965 and sold it to S. 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. 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. In the late 1970s, the product was reformulated as a combination of liquid lye and sodium hypochlorite.
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.
