Abstract
Abstract Process for cleaning road film from road vehicles with a dilute aqueous solution of a cleaning composition. The cleaning composition is a mixture of 15-90 parts condensed phosphate, 2-40 parts alkaline builder, 5-60 parts alkali metal chloride, 1-25 parts higher alkylbenzene sulfonate, 1-15 parts of fatty lower alkanolamides, 1-10 parts polyethyoxylated fatty alcohols or alkylphenols, and 1-30 parts of a hydrotropic agent.
