Abstract: A cleaning formulation for removing materials from a surface (e.g., an optical surface, a metal surface and the like), the cleaning formulation comprising from about 0.5 to about 60 weight percent of a compound derived from urea and a phosphorus-containing acid, together with a carrier therefor. A method for removing fouling materials from a surface is also described. The cleaning formulation may be used to remove materials, inter alia, from optical radiation surfaces, optical lens surfaces (e.g., a contact lens) and the like.
