General Description

CTW-32 is an aqueous blend of acid, detergents and water-soluble solvents designed to rapidly clean concrete or masonry products from painted or unpainted metal surfaces. CTW-32 is also very effective in removing hard water and scale deposits. CTW-32 is also effective in removing rust and some types of oil stains from concrete by dissolving the stained areas. CTW-32 is also recommended for acidizing concrete prior to painting to assure good adhesion of the coating to the cement. CTW-32 contains corrosion inhibitors to minimize the attack of acids on metal, chrome, and aluminum surfaces. CTW-32 is formulated to work quickly and effectively, thus minimizing the amount of time the product is in contact with sensitive surfaces.



CTW-32 can be used as provided, or diluted with water up to 20:1. Pre-wet surface to be cleaned, spray product on and allow adequate time for penetration of soils, rinse throughly with clean water. On vertical surfaces, apply product to wet surface from bottom to top to avoid streaking.
