WHAT!!!! No hearing protection?
I use Sterile Rolled cotton, Sterile USP grade, good for surgical use as per the box. If they can use this to stuff into me or on an open wound I have no problem making a wick out of it.
Everyone boiling other cotton I guess is their choice, just remember if it starts out sterile and then you boil it you are introducing moisture that, while the water you use may be distilled unless you dry it in a sterile environment there is no guarantee that is is still sterile, especially with all the moisture you have infused into it. Sounds like a good place for bacteria and virus's to grow. I guess once dry you could micro-wave it for a couple of minutes and that might help, or maybe not.
I say KISS is the way to go.
