Is it bad for the environment to dump clog removers like Drano down the drain?
The active ingredient in Drano and other conventional drain cleaners is sodium hydroxide, otherwise known as caustic soda or lye. It is a man-made chemical used for its corrosive properties. According to the federal Agency for Toxic Substances and Disease Registry, the substance is not considered a pollutant per se, as it separates into relatively harmless component elements once released into water or moist soil.
