The boards can be cleaned with a number of solvents.   If you still
have a shop in town that sells electronics supplies you might check
there for a can of flux remover or flux cleaner.   This will remove
pretty much any kind of crud from your board.  You'll want to use it
outside, as flux remover tends to include things like toluene and
MEK.

Other acceptable solvents are isopropyl (rubbing) alcohol, provided it
does not contain any skin lotions, so the only ingredient besides
alcohol should be water.   Our local grocery sells a 91% solution.
Home Depot sells a one gallon can of denatured alcohol which would
work, but that's probably a bit more than you'll ever need.

Finally, for the last rinse distilled water is a good choice.

Or you can run it through the dish washer with no detergent and no dry
cycle...

Not directed at original poster--would you folks please trim your
quoted text?   It is very inconvenient for readers to page through the
ridiculous amount of quoted text you are leaving attached to your
messages.   This list is quickly becoming unreadable because of this
lack of consideration.
