Abstract
Abstract Disclosed is a new and improved, environmentally acceptable and negligibly corrosive deicing composition comprising by-products from a wet milling process of corn, which by-products are biodegradable. 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.
