Iodine and YPS can cause a localized tint to the water or yellow staining on the cementitious finish if allowed to rest undissolved on the finish for extended periods of time. AutoSoft Plus™ is blended with the proper amount of stabilizer to maintain a proper level within the recommended range when added according to the salt chart on the box. Granular Salt, Table Salt, Solar Salt or Water Conditioner Pellets can also be used but will have different dissolve rates.

the salt. Ensure that the salt you use contain a minimum purity of 99% Sodium Chloride (NaCl).
