BG-150 is not only the strongest masonry cleaner in the world, it is also the safest. Independent tests confirm that BG-150, the world’s only synthetic acid, dissolves more calcium oxide and efflorescence than muriatic (Hydrochloric) or phosphoric acids, the active ingredients in virtually every other masonry cleaner on the market. Cleaner will safely and quickly clean pavers, block, brick, concrete, river rock, architectural concrete, and retainer walls while dissolving all signs of efflorescence. Plus, it is safe on even the lightest colors. This non-fuming, purely synthetic formula is non-D.O.T. regulated while exceeding OSHA & EPA compliance standards. In fact, it is so safe that it carries a USDA Authorization Code of A1, deeming it safe for use in and around food processing areas and equipment. It is 100% biodegradable, water soluble, non-toxic, non-butyl, and non-flammable.

Belgard Masonry Cleaner is 100% acid-free, so no neutralizing step is required. This also means it will not etch glass, is non-corrosive, and will not harm plants or turf. Simply dilute, apply, agitate, and rinse.
