Daryl is on the right track with that, as sunshine over time will only result in fading the wool baize. Though fabric softener sheets would likely do it, I prefer keeping a small ventilated, plastic 35 mm film canister containing a few mothballs in each of my gun boxes, as it eliminates any concern over the moths that can eat away your fabric pretty quickly. I don't find the odor objectionable, and at any rate it beats the smell of mold, IMO.
I've been able to find them here in several box stores listed as 'Enoz Old Fashion moth balls'. They contain 99.95% naphthalene as the active ingredient, and should add that they are not sold in the state of California. Just two or three balls in a film container will last for several years in one's gun case before needing replenishment. Best odor/insect protection I can think of.......
