Eric:  Whereas IPA may well give you a good clean, it will probably worsen the problems you are seeing with water...

And then there might be some minor issues with flammability, and the fact that you will need an explosion proof US cleaner...

Other than that, it is a GREAT IDEA... :-)

We've been directed to use IPA rather than DI water as a cleaning medium
to give a gentler clean to reduce damage.

Does this sound like a good plan and would there be any other fluids
that would be more suitable?
