I have seen references to mixing IPA and acetone 50/50 to do some PC
board cleaning. Any thing good or bad about doing that ?

No. Bad idea. Don't do that.

Acetone will attack many plastics (ABS, polycarbonate, polystyrene,
polyethylene, vinyl, etc). Before you use ANY manner of solvent, do
some research on a "chemical compatibility chart" for the materials
you expect to be using.

Be sure to check compatibility with epoxy, as that's what the PCB is
made from.

For example:

shows that:
ABS plastic and acetone = "Severe Effect"
ABS plastic and 50% acetone and water = "Severe Effect"

Thanks for the chart. I will stay away from the acetone/ipa mix for the
PC boards.
