Abstract
Abstract Disclosed is a new and improved, environmentally acceptable and negligibly corrosive deicing composition comprising by-products from the production of cheese from various milks. The active ingredients of the present invention are the liquids that remain after the coagulated cheese has been removed from the milks, said liquids being commonly known in the cheese making industry as "whey." The invention also relates to the use of a deicing composition in a manner that helps to reduce the buildup of snow and ice on roads, bridges and other outdoor surfaces.
