[Boatanchors] Water, Water Everywhere.

[Ian Wilson]

Hi Dave,

I wonder if you can displace the moisture by isopropyl alcohol, then
evaporate away the solvent. Since IPA (not the beer kind) is 100%
miscible with water, I think this would work better than, say, using
switch cleaner in an attempt to displace the water.
