Southcrete™ Masonry Cleaner & Efflorescence Remover

Southcrete™ Masonry Cleaner and Efflorescence Remover safely and quickly cleans a variety of cementitious substrates, such as masonry, concrete, brick pavers, river rock, architectural concrete, retainer walls, et cetera, while dissolving all signs of efflorescence. This special synthetic acid formula dissolves more calcium carbonate and efflorescence than muriatic (hydrochloric) acid-based or phosphoric acid-based cleaners. This cleaner can be used to prepare stone and masonry surfaces for clear sealers, stains, or paints, or to simply restore the original beauty and natural look.
