ABSTRACT:
An apparatus, formulation and method for cleaning soils, such as paint drips or splashes, from the outside surface of filled aerosol paint cans and other articles is provided. The apparatus comprises a plurality of reservoirs containing liquids for cleaning and rinsing articles. Articles to be cleaned travel on a conveyor system comprised of one or more mechanical conveyors. During the cleaning operation, one or more brushes apply cleaning solution to the articles, an air knife blows excess cleaning solution and/or solid soils off of the articles, and a jet spray rinses the articles. Another air knife may be used to dry the cleaned articles. The apparatus also includes a plurality of recirculation devices for removing solids from the cleaning and rinsing liquids so that these liquids may be reused in the cleaning operations. A cleaning formulation comprised of a glycol ether and hydrocarbon solvent is also provided.
