Soak the heck out of it in vinegar first.
Actually I would try chlorine bleach full strength first.....with rubber gloves, old clothes and glasses.
Wash it out good, leave it a little damp and then close it for 24 hours and then rinse good.
That should replace your moldy food smell with a chlorine smell.....which should dissipate over time.
For less drastic things I have been using a cleaner with bleach in it. It works good for lots of stuff.....including dumping a bit into the tanks for cleaning.
DO NOT MIX CHLORINE BLEACH WITH VINEGAR OR ANYTHING ELSE. That can result in releasing deadly chlorine gas.
