There is an issue with wood, the salt soaks into the wood and will crystallize once dry. Most of the non metallic artifact I find while scuba diving in saltwater are soaked in fresh water for a long time to leach out the salt. The best place is in the water tank, no the bowl, of a toilet, this changes the water regularly. I have some wooden deadeyes from the 1700's I soaked for 1 year and then soaked in walnut oil and they look great, my buddy did not soak his and they are powdery and flaking apart. As with most wood the type of wood and the time in water have a lot to do with the how much salt penetrates the wood. This is also true with other items, including glass, leather and fabrics, you can do a search on dive artifact restoration for more information.
