I have a pair of headphones that I use regularly, including while I'm working out. They're the kind of headphones that sit inside the ear (earbuds), so inevitably they'll get kind of gross after a couple uses. They have the removable rubber tips on them, but I don't think that helps keep everything out of the speaker part.
It's easy to wipe the occasional earwax out of the removable rubber tips, but for the inside parts where the speaker is I'm having trouble with making sure those are clean. Normally I'm able to clean any earwax that makes it through the rubber tip using a toothpick or a piece of paper that I've folded up, but I would actually like it to get sanitized when it's cleaned, since I use them while working out they could harbor some bacteria, and I would rather not get swimmer's ear from them.
Is there a better way I can be cleaning these kinds of headphones?
