A deicer is a substance or a device used to remove or prevent the build-up of ice or frost, especially on surfaces like roads, aircraft wings, car windshields, and other surfaces where ice can cause safety or operational issues. Deicers usually work by lowering the freezing point of water or by physically breaking up or melting existing ice.
