Carrie, Have you looked at the citrus based cleaners. It seems they are everywhere and there claim to fame is machined parts,(oil, fingerprints etc.) cleaning. I would do a hot water rinse after the citrus cleaners. Also most of these cleaners are very enviromentally friendly. Good luck Tony Steinke ----- Original Message ----- From: "Morse, Carrie" <[log in to unmask]> To: <[log in to unmask]> Sent: Monday, September 09, 2002 1:24 PM Subject: [TN] Cleaning Aluminum I am looking for a cleaning solution to be used in conjunction with our Ultrasonic cleaner that will remove organics (such as finger oils) from machined aluminum parts. Some of the parts are straight aluminum (untreated), some are clear anodized, and some are clear chromated. Preferably, I'd like to find one cleaner to fit all. We are currently using Branson's MC-3 which is far too harsh and has resulted in aluminum oxide deposits and/or tarnishing even after repeated attempts to decrease time and dilution per the mfr's recommendation. At this point I'm ready to use some Joy Dishwashing detergent, but, would rather use a product designed for industrial use that cost 100 times more so the customer's perception of our cleaning process will be enhanced :) Due to the nature of the product these parts go onto, "cleanliness" cannot be determined until after an entire unit is built and tested. Therefore, I'm simply looking for companies that sell cleaners that are intended to remove organics and I'll have to build samples and have them tested at the customer site. (oh what fun!)
