take it in to repairs see what they say if they tell you they cant fix it,,, i have a random idea you can try! - at the mesuem i went to a few months ago they were collecting wood planks from the ocean, these planks were full of salt and they had to get rid of the salt to preserve it. so they soak it in water? (i think, it might have had some chemical added to it like... i cant remember) then they use a Cl (HCl (salt)) monitor to monitor the water and when it gets to 7% salt they take it out and put it into the next water tank to soak out more salt........ until there is no salt left, then they dry it and the salt isnt there to crystalise and expand to ruin the wood!!!
