Washing it properly and keeping it dry was all I did. And giving it some air time, which was a bit hard middle of winter LOL

It did get a bit itchy at one point, so I put bepanthen on it (bepanthen is my wonder cream PMSL I use it for everything hahahahaha) and that helped. I think there are some essential oils that can help, but I'm not sure what they are. I'm sure someone will come on and give some suggestions. But my experience is that you don't really need anything heavy duty like betadine unless you have problems with it.
