I removed the bad batteries and replaced them but nothing would power on. I took the electronic components out and noticed a lot of white powder had leaked out and was corroding the metal. I used some vinegar, water, and a dozen or so Q-tips to clean everything up, but there is a bit of damage to the wood grip (more of a stain) and the battery cover plate had some damage. A bit of paint will clean it up.

The lesson here is that I'll be removing the batteries completely if I plan on letting everything sit for more than a few weeks.
