Through the use of OSEE, the lab compared the two cleaning processes for the client. Upon review, one system was determined to be slightly better than the other. Additional testing was performed on three cleaners for comparison purposes. After initial testing, a couple of aqueous cleaners were very effective in removing the buffing compound from the brass substrate through immersion cleaning. At a 10% dilution, four products were successful in removing most of the buffing compound.
