Abstract

306,604. Cole, W. H. Aug. 22, 1927 Divided on 298,328. Cleaning; coating.-A process for removing rust, scale, dirt, and grease from iron and steel articles comprises heating them in an autoclave with dilute phosphoric acid. The resulting iron phosphate solution may be used for the production of rust-proofing solutions described in Specification 298,328.
