Disinfecting and cleaning

A couple newbie questions

  1. I have a Hohner Silver Creek Beginner Harmonica that I think has a metal comb. I’ve seen videos on how to clean plastic combs but unable to find info on the metal ones.
  2. Is there a product I can use daily to disinfect the outside of my harmonica? Is it wise to do so, even with cold and flu season? Plus, our mouths are breeding grounds for germs.
    And if I sound like your mother, I’m probably old enough to be her LOL

I’ve always used Listerine mouthwash to disinfect harmonicas. Just rinse it well afterwards.
