Abstract:

The patent application pertains generally to surface cleaning techniques and in particular to techniques for completely removing oxidized iron from from ferrous metal surfaces without damaging the metal surface. This method for microscopically removing iron oxides from a ferrous metal surface without damaging the surface comprises of submerging the surface in a liquid mixture comprising one part of a phenyl-2-pyridyl ketoxime solution with a concentration from 0.15 to 0.2 weight percent, from 13 to 20 parts of 3M to 10M sodium hydroxide, from 13 to 20 parts of iso-amyl alcohol, and from 1 to 3 parts of ethyl alcohol until the iso-amyl alcohol turns red. Then the surface is rinsed with iso-amyl alcohol and ethyl alcohol, and dried.
