        True. The Contamination Engineer on the NASA program I'm working on
swears by "Simple Green", a widely available (grocery-store) detergent, for
removing silicon grease. She recommends the clear, unscented version of it,
which she uses on our flight hardware.
        She still hates silicone greases/oils/release agents, though,
because it *is* hard to get off once it's on, and it does tend to
flow/spread all over anything it's put on.
