Ok so just a quick question. I have been checking out a lot of stuff about using cotton balls and boiling said cotton balls for up to 15 minutes but, is there any evidence that says this helps with anything at all or any evidence that says that the cotton ball manufactures do not heat and soak their product after they whiten them? Just curious if there is any scientific evidence out there supporting this boiling thing. I have to imagine that these things are made as clean as possible seeing as they are used to treat cuts, burns, apply/remove makeup and the like. I have been thinking about using cotton wicks but I would like to have some facts before doing so. Thanks!
