Abstract: The deicing agent described comprises an aqueous solution of at least one alkali metal acetate or at least one alkaline earth metal acetate or a mixture of the two, and water as the principal components, and from 0.01 to 1% by weight of at least one water-soluble triazole compound or at least one water-soluble imidazole compound or a mixture of the two, and optionally from 0.01 to 0.5% by weight of at least one alkali metal phosphate as inhibitors. The process described for melting snow and ice on traffic surfaces comprises applying the novel deicing agent in an effective amount to the ice- and/or snow-covered surfaces to be treated.
