A powerful acid based brick cleaner which removes rust, scale, efflorescence salts, moss, stains, algae and cement from brickwork, stone, tiles, metals, masonry and equipment. It has been formulated with a blend of detergents, wetting agents and corrosion inhibitors to give maximum effectiveness without damaging or burning the surfaces. Can also be used to remove oil from concrete as it penetrates down below the oil and floats it up to the surface. Excellent cleaning action. Quickly dissolves rust and scale. Contains no solvents. Concentrated - Economical to use. Safe on most building materials. Contains biodegradable surfactants. Works well in both hard and soft water areas. For brick and masonry cleaning apply diluted with up to 10 parts of water depending on the level of soiling. Apply with a brush, mop or low pressure sprayer. Allow it to work for a few minutes and agitate if necessary. Rinse all surfaces thoroughly with plenty of clean water. For concrete etching dilute concentrate with 2 parts of water and apply liberally to the floor. Leave for a few minutes and rinse thoroughly. Can be used effectively to clean metals and remove rust but it should not be used on brass, chrome, anodised aluminium or stainless steel (Steelite is an excellent alternative for cleaning these metals). Please note: the effectiveness of oil removal will be dependant on the age of the oil stain and the porosity of the surface. Contains Hydrochloric acid (muriatic acid) and phosphoric acid.

Primary efflorescence is named such, as it typically occurs during the initial cure of a cementitious product. It often occurs on masonary / brickwork when water moving through a wall or other structure, or water being driven out as a result of the heat of hydration as cement stone is being formed, brings salts to the surface that are not commonly bound as part of the cement stone. As the water evaporates, it leaves the salt behind, which forms a white, fluffy deposit, that can normally be brushed off. The resulting white deposits are referred to as "efflorescence" in this instance. In this context efflorescence is sometimes referred to as "saltpetering." Since primary efflorescence brings out salts that are not ordinarily part of the cement stone, it is not a structural, but, rather, an aesthetic concern. (source: Wikipedia)
