SKB; I won't claim to be an expert on this sort of thing, but it would seem to me you need to remove the salt (brackish water is salty I would guess). About the only thing that will disolve the salt is water, so therefore I would soak the stock in a about a 50/50 acetone/methanol and water solution for awhile (a day) and repeat a couple of times with a fresh mixture, this should dissolve & remove the salt. Then remove the water from the stock with acetone ( acetone loves water so you should see it turn "milky" when it befores saturated) or just dry it out naturally. You'll likely have to de-fuzz the stock before refinishing as the water will raise the grain somewhat. For your on curiousity you can evaporate the "soaks" to see how much junk you did remove. I would think this method would work on the so called "salt cured" stocks should one have the need. --- John Can.
