Smelly leather purse.

place a open box of baking soda inside

charcoal absorbs odor well. If you like the smell of coffee, fresh ground coffee works well too. (Do not brew it!)

You can try spraying the inside of the purse with rubbing alcohol. Dont get it on the outside.

I sprayed mine with white vinegar and left it in the sun to dry and air out, then wiped it down with some leather cleaner. The vinegar left a white residue that the leather cleaner took off.

Febreeze spray, even the generic kind, will help. But airing it out is key as well!

Put the purse outside for a couple of days. The odor will dissipate.
