Carrie,
Tony gives good advise.  Terpines are good cleaners that just need plenty of rinsing.  If there are stubborn stains you can use dilute phosphoric acid.

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

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!)

Thanks,
Carrie
