ABSTRACT:
Generally, and in one form of the invention, a method is presented for the photo-stimulated removal of reacted metal contamination 16 from a surface 11, comprising the steps of: covering the surface with a liquid ambient 14; exciting the reacted metal contamination 16 and/or the liquid ambient 14 by photo-stimulation sufficiently to allow reaction of the reacted metal contaminantion 16 with the liquid ambient 14 to form metal products; and removing the liquid ambient 14 and the metal products from the surface 11. Other methods are also disclosed.
