How to get the mildew smell out of a sauce pan?

I had some stuff in an outside storage container that ended up being there much, much longer than anticipated. I had to throw out a bunch of stuff due to mould/mildew but I have a saucepan that I'd like to keep. Trouble is, it reeks of that mildewy smell. Other than the smell, it looks brand new. I've washed it (with dish soap) about 4 times and have left it soaking in hot water for extended periods of time a few time as well. The smell is still there although not nearly as strong as it was earlier.

Is it salvageable? Is that smell something that can get into the metal? Is there something lurking inside the handle? What can I do to get rid of the smell?
