Thanks for the useful information
Thank goodness only a portion of the stocks are salt contaminated - from the comb backward. I shall try a distilled water soak mentioned by smoakingun. Interestingly, two stocks that were swollen are slowly contracting without any treatment but corrosive salt remains.
Agree that this is the forum for such topics; although, Gecko 45 and zombie threads have been "informative." By the way, WD40 is never my choice for firearm application but it was the only water displacement agent on hand at the time.
