Applied Surface Technologies will demonstrate CO2 Snow Cleaning as applied to cleaning and restoring art. We will demonstrate the CO2 Snow Cleaning units, with and without heated compressed air about the CO2 snow stream, for cleaning different materials and items. CO2 snow can remove soot, hydrocarbon oils, fingerprints, dust, particles of all sizes, polishing residues and more. Examples shown include fingerprints on a polymer structure, polishing and wax residues, soot and, more.
