ABSTRACT:
A method is provided, to render non-hazardous, surfaces which are coated with lead-based paints. A composition comprising an aqueous mixture of hydrogen peroxide, ammonium hydroxide, nitric acid and acetic acid is poured on the surface and, after a time, water is poured onto the surface to remove the lead-based paint. The method is effective on surfaces which may be comprised of wood, metal, concrete, wallboard or plaster without destroying the integrity of these surfaces.
