One product was selected base on client input from previous testing. The product was heated to boiling (160 F) in a vapor degreasing chamber on a hot plate. Twelve preweighed aluminum coupons were coated four different contaminates, thee coupons per contaminant. Coupons were reweighed to determine the amount of soil added. The coupons were cleaned for 5 minutes in the vapor zone, then removed and allowed to cool to room temperature outside the chamber. Final weights were recorded and efficiencies were calculated.
