A method for facilitating the removal or preventing the adherence of residual oil in oil tankers and other vessels or containers, on the surfaces of oil spill cleanup equipment such as skimmers and booms, and on sucker rods or other surfaces in oil wells, by coating surfaces contacting the oil with a film of a polymer that prevents or reduces oil adherence. Materials effective in reducing oil adherence are oleophobic films formed by complexing a polyacrylamide or carboxymethylcellulose in the presence of water with salts of polyvalent metals such as aluminum, chromium and iron.
