Direct sunlight will fade leather and speed up any chemical reactions that
cause drying, cracking, deterioration, etc. Hang it in a shaded, airy spot
(on the back porch?), on a hefty hanger that will hold the front from the
back, perhaps even stuffing the sleeves with tissue. Or, if you have an
ozoneemitting air cleaner, put it in a small, closed room with said air
cleaner running. THis is the technology used by commercial firms that come
in and clean up and sanitize after a fire.

That's not the best thing to do to leather though, maybe try the dry
cleaners instead.
