We had a basement flood once when we moved into a rental house. Our vintage wood furniture was there and luckily not ruined. Later we noticed a really strong smell so we read online and found out that BBQ charcoal briquettes work great. This has been mind go to remedy for musty smelly items. I buy a large bag and slit it lengthwise and just sit it where I want for maybe up to a week. I think this will solve your problems good. If there is still mold or mildew, make a solution of a tablespoon of bleach into a cup of water and spray lightly onto those spots, bleach kills mold.
