USC’s solar crystal water softener salt is a pure white crystalline product selectively harvested from our crystallized salt bed in Carlsbad, New Mexico.

USC solar crystals are produced naturally from a 2,000 acre lake using the energy of the sun. The crystals are harvested only after reaching their optimum size.

The salt crystals are double-washed, then evenly kiln dried to ensure the highest purity and whiteness to produce a crystal clear brine.
