A non-toxic, acid-free cleaner that effectively removes calcium deposits and efflorescence from pool tile. Calcium deposits are removed in layers through the use of advanced acid-mimic technology, which specifically targets mineral build-up without damage to the tile surface or metal finishes. When applied prior to media-blasting, Calcium Releaser softens and loosens deposits, which allows for the use of less aggressive media, reduced blasting time and reduced media consumption. Designed for use with porcelain, ceramic, glass and iridescent glass tile.
