Denture tablets, with HOT water. Two in a 32 ounce, one in a 16 ounce. Let sit until the water is cool. Wash by hand with dish soap, rinse well, let dry.
If that doesn't take care of the "funk", make lemonaid in it, and let it sit over night. As was mentioned, Vitamin C neutralized iodine and chlorine history.
If you had metal corrosion, hows your laptop doing? I'd advise backing up early and often if you think your hard drive might have been in an iodinized enviroment.
