The monosodium and monopotassium citrates are improved iron-sequestering agents in salt compositions for regenerating spent water softener cation exchange resins. The dry compositions comprise a surfactant, an alkali metal chloride selected from the group consisting of sodium chloride and potassium chloride, and an iron sequestering agent selected from the group consisting of monosodium citrate and monopotassium citrate. The composition is preferably provided in the form of compacted pellets or blocks. The method for regenerating the spent cation exchange resin bed comprises the step of contacting the resin bed with an aqueous brine solution containing the citrate and a surfactant and having a pH of about 3.5 to 4.5.

Water softener salt formulation

A deicer composition contains a deicing compound plus between about 0.5 and about 5.0 weight percent of a gelling agent, such as hydroxyethyl cellulose, to minimize spalling of concrete to which the deicer composition is applied.
