Sunshince and ultra violet will kill any mold and the fresh air and sunshine gets rid of the smell. Wipe the wood down with Orange Glo wood polish and rub. The coffee will help the case. As a last resort on the case, place it in a sealed bag OUTSIDE, with a half and half mixture of clorine bleach and vinegar. Mix this outside and be careful, as it produces CLORINE GAS. I've used this on fire damaged goods and books, ...will kill any mold and smells.
