Ok, got used Cambo Legend off ebay and it looks like the thing has been in storage for quite a while. It had a horrible "storage" smell to it. I doubt it was mildew or fungus since there was no mildew stain - maybe I'm wrong. I ripped apart all of the foam on the casing and poured baking soda all over the wood and let it sit in the sun. The bellows is kinda smelly too so I had spread baking soda all over the surface of the bellows and stuck a pouch of baking soda inside the bellows as well.
Am I doing the right thing to remove the bacterias and smell? Tonight I dusted off all the baking soda from the bellows and it is smelling a lot better. I plan on spraying the case down tomorrow to get rid of all the baking soda and allow it to sit in the sun until its bone dry. I hope I'm not damaging the case or bellows in any way by doing this. What should I apply to coat the bellows now that I've got it all cleaned up?
