Abstract
A method for cleaning thin gauge metal foil strip material using a plurality of wiper ( ) and solvent application ( ) stages. The solvent used in the solvent application stages is an aliphatic petroleum type which is applied using low pressure to avoid atomization or separation of solvent components. The wipers of a first wiping station are made of a solid bar of polymer impregnated fiber material. The wipers of the second wiping station are spaced apart blades of urethane-based elastomer material.
