Back in 1980 I had a job repairing terminals.  A few of them came in contaminated inside and out with very fine ash.  Think of a major volcano in the northwestern US in 1980.  It was upwind of some of our locations.  Water did the trick on all but one.

But an ADM-1A with through-hole TTL is a damn sight harder to damage than a disk drive from 2005.  YMMV, verily.
