Silibrite SMS softens hard water (especially Ca and Mg), allowing surfactants to be more effective. Silibrite SMS inhibits scaling and corrosion by laying a protective coating over the cleaned surface. The high pH of Silibrite types breaks down dirt.
Silibrite SMS anhydrate contains no crystal water, is more effective and more expensive than Silibrite SMS pentahydrate (5 molecules crystal water per molecule per metasilicate group).
