Abstract:

A polymeric residue with one or more metals, salts, and oxides mixed therein, deposited on refrigeration system surfaces by a circulating halogenated hydrocarbon refrigerant, is removed from a surface by contacting the residue with a saturated aqueous solution or slurry with a pH from 2 to 4 of ethylenediaminetetraacetic acid at temperatures from 30 C to 100 C.
