Drano is a toxic acid used to dissolve hair and grease from drain pipes. The crystals are made up of sodium hydroxide, sodium chloride, aluminum chips and sodium nitrate. Other inert ingredients give Drano its color and odor. In diluted quantities, sodium hydroxide, also known as lye, is used for making soap and detergents. Higher concentrations cause a caustic reaction that dissolves the clog. You must use care when working with Drano and take precautions if the product accidentally spills.
