If you’ve got a leather coat with a smell you’d like to remove, throwing it in a washing machine isn’t the solution. Before you pay for expensive dry cleaning, try this DIY idea instead: Take an old nylon and fill it with charcoal (even briquettes for the barbecue work). Stuff the jacket sleeves with newspaper, and throw it in a clean trash bag; add the nylon briquettes and seal the bag. Let it sit for five days. The newspaper and charcoal will absorb odor and freshen your smelly leather coat.
