F-2020-HD is a true breakthrough concentrated cleaner. With a pH of less than 1, this multipurpose cleaner generates the high cleaning power of an acid, yet it is safer and mild to the skin, like liquid dish soap. Cleans stains and rust from concrete buildings and walks; removes cement from construction equipment, trucks, pouring forms, structural steel, and tools; dissolves hard water build-up, lime, scale, and corrosion in boilers, air conditioners, and refrigeration units, condensers and circulating systems.
