You may want to try petroferm.  I do believe they have a facility just for
this kind of cleaning.    They do a pretty good job on most residues and
usually can come up with something that will help you.
WWW.petroferm.com        This link will get you where you can ask them for
help and maybe get a name or two to talk to.

We have a large aluminum casting
Good afternoon,



We have a large aluminum casting (35 inches long by 10 inches wide by 10
inches high and weighs about 75 pounds) that forms the outer enclosure
of a finished product.  After full assembly this unit it filled with
dielectric oil.  For units which require repair after failure, we want
to clean out the old oil and any residue from the failure or from
machine shop rework.  We would like a system that does not drain into
the local sewer or waste water system.  Where this unit is used at 180kV
we need to get all the conductive schmoutz out.  What are recommended
cleaning methods?  Is there a MIL or NASA spec for cleaning large parts
like this?



I know that a final wash with DI water is probably the best, but what
would cut the oil best and what method of application?
