Abstract: My invention is different in that it uses high temperature water to dissolve either evaporated granular salt, evaporated salt blocks, evaporated salt buttons, solar salt blocks, bulk or bagged solar salt crystals, or halite rock salt crystals to create a highly saturated, highly concentrated salt brine with or without adjuncts such as waste beet juice, molasses, calcium chloride, magnesium chloride to deice streets, roads, bridges, highways, sidewalks, curb cuts, building entrance steps, and airport runways and airplane taxi ways leading to airport runways. The use of the heated salt brine and adjuncts such as waste beet juice or molasses will prevent the solution from being diluted by holding it place with the sucrose or fructose based molasses used to bind the brine to the surface requiring deicing. The use of calcium chloride and magnesium chloride as adjuncts will increase the heated salt brine's effectiveness at lower temperatures.
