<Eek! Really? Does this work?

Yep. In the past (over 20 years ago) I used to do it in the sink with a
bristle paint brush and some liquid soap.

<Were these just the power supply boards, or all of the OMNIBUS
<boards too?

All but the core plane and front pannel itself. The little cores would
not like the blasts of water pusing them around. I didn't want the
switches washed out as then I'd have to get some lubricant back into
them.

I've done this with all sorts of boards to get gunk off them and it's
basically how boards are cleaned at factory. HINT, keep the temps below
200f.

<I recently got a PDP8/E system (it runs well), with 16K core and
<8K solid state memory, and it's really grubby inside, and I've been
<thinking about how to clean it all up. Can you share some secrets
<on the settings used, ie: do you use any soap in the dishwasher?

I put it in and ran standard cycle (short wash). The CORE planes do not
ever go in and also if there are switches that can trap water special
care may need to be taken.

Things must be dry before power up or electrolisys and other bad things
happen. Pure water is generally harmless.

Soap, I used one of the standard products that seems to work well on
glasses.
