ABSTRACT:
A rust-removing composition comprises alkali metal hydrogen citrates, water, optionally citric acid, and optionally a thickener. The invention further provides a method for removing rust from rusted metal surfaces, concrete surfaces, and the siliceous surfaces of natural stone by applying the composition, allowing contact until substantially all of the rust is removed, and washing away the composition and dissolved rust with water.
