A deicer effectively disintegrating a layer of ice and preventing further frosting and accumulation of snow, ice and hoarfrost, with minimized corrosiveness and acceptable for environment. The agent consists of water solution of at least one acetate and/or formate of alkaline metal or their mixture as the main components, 0.005 to 0.01 weight per cent of at least one water soluble alkyl phosphonium acid, while the carbon number in the alkyl is C1-C4, in combination with zinc ions. Application of this agent removes snow and ice from roads and other operation surfaces.
