Luckily, no potentiometers on the boards I washed. I was concerned about this
issue, too, but when I looked over the two boards that I planned to wash, I was
glad to find that neither had any 'moving parts' components, mostly just
descrete stuff, with an odd IC or two. I think I'm okay on this issue.
