Cleaning Old Soda Off Of A Circuit Board?

[phaeton]

The great bulk of the wash can be done with warm tap water, even hard
water. Just the final rinse is best done with distilled water.
Before that, the contamination being washed off is dirtiuer than the
tap water. No sense rinsing gallons of distilled water down the
drain, brown with Coka Cola.

Excellent. I think I'll go down to the car wash with it this weekend,
and do the 'low pressure' hot soapy water thing. I'll then rinse it
with the wand (low pressure also) but then also tug along a gallon of
distilled water for the final dousing. I'll let it sit somewhere warm
and safe for a week before putting it all back together.

What's neat about this is that the preamp and power amp are on
separate boards (connected by ribbon cable) and then the transformer
(which is the size of my fist) is butt-connected to the power amp
board. The transformer can just be wiped down with a damp sponge
(only a few drips on it), and I can pull both circuit boards off and
roll down to the car wash round the corner.

Thanks for all the help, folks. Wish me luck!
