I was just saying I wipe them down with the 91% isopropyl alcohol after I have sweat on them to kill the germs before putting them in the case. I do not do it every time I use them, but isopropyl alcohol does kill bacteria and isopropyl alcohol is great for wiping down electronics.
*Unless more bacteria is introduced (obviously) the isopropyl alcohol will kill basically all the bacteria that would be on the AirPods, and for more than a minute.
Why do you think we in the medical field (well nurses, I am a M.D.) wipe down your arm with isopropyl alcohol before poking you with a needle for blood work, or use isopropyl alcohol to wipe down an IV injection port before putting medication in your IV?
-Sometimes I prefer using pure liquid 91% isopropyl (you can buy it any pharmacy for super cheap) over the ethyl alcohol based gel hand sanitizers. Now in some hospitals they are using hand sanitizers for visitors and staff (hanging on the walls) that do not use ethyl alcohol, but instead use Alkyl Dimethyl Ethylbenzyl Ammonium Chloride and
Alkyl Dimethyl Benzyl Ammonium Chloride (ADBAC) which I personally do not like as much as ethyl based hand sanitizers.
Sorry for getting way off topic there, but hey if you do not work in the medical field you learned something new today, haha.

Seriously though, sorry.
