摘要

1. A process for washing gaseous effluents emerging from paint-applying booths and for removing paint from grating constituting the floor of said booths, wherein, upon the application of the paint, the gaseous effluents are washed with an aqueous washing composition, characterized in that a washing composition containing water-soluble detergent metallic salts is used, said salts being present in the composition in such proportion that the density of the composition is 1.1 to 1.45 and the pH of the solution is adjusted to be between 7 and 14, and, periodically after paint application, the grating is immersed in said composition.
