How can I clean a leather jacket at home and get rid of musty smells?
Start with just general leather maintenance, conditioning the leather and weather proofing it. If it still smells a bit off, then take something like a shout wipe (or similar) to the cloth on the inside or just plain febreeze. You can also always call a local leather shop. Any place that specialises leather jackets will be able to sell you leather conditioner and give you additional tips on how to rid yourself of the smell. Just don’t let them bully you into getting it professionally cleaned/conditioned without a go yourself first.
