Last week I bought an Ibanez GSR206, (which I'm on the fence about defretting, but that's beside the point). I ran into some personal stuff since I bought it, and wasn't able to change the battery right away. Today, I finally had some free time, and I got around to changing the battery; however, the battery leaked inside the battery compartment. My question is how I could clean the leakage in the compartment, without damaging the wood? Also, opinions on defretting the bass?
