Hey guys, my grandpa died and he left behind an old harmonica, or at least I think it’s old. Id really love to use it but unfortunately I’m a big germaphobe so I’m wondering how I’d go about cleaning it. It looks like a mixture of metal and wood. Here are some pics.

Any help is appreciated, I also am not really sure what I have so any knowledge is also appreciated. Thank you!
