The musty smell is mildew... pretty sure the only thing for that is a good deep clean, and wiping all surfaces with a disinfectant like lysol or pinesol.

[Phil Nelson]

Whatever cleaner you use, do the inside of the cabinet and the rear cover, as well as the exterior surfaces.

If you live where the sun shines (ha ha, not here!), letting it bake in direct sunlight for a while can also help.
