How do I clean a moldy typewriter?

I recently bought a typewriter at Goodwill. It's actually in pretty good condition. My only problem is that there's some dusty mold on it. (Green dust is mold, right?) I've vacuumed the case and cleaned the outside with soap and water. (The case is lined with velvet, so I didn't wipe the inside.) It smells really musty, so I'm airing it out right now. I also set a box of baking soda inside of it. I cleaned the keys with soap and water. The mold is located on the metal at the bottom of the typewriter. I wasn't sure how to clean this part, so I just wiped off some of the dust with cotton swabs. How else should I clean the typewriter? I just want to make sure that it's safe to display inside the house.
