Everyone seems to talk about hydrogen Peroxide used in bleaching cotton and the need for boiling to "remove the hydrogen peroxide" by boiling.
From the New World Encyclopedia entry on Hydrogen Peroxide: "Decomposition
Hydrogen peroxide always decomposes (disproportionates) exothermically into water and oxygen gas spontaneously"
So, If my assumptions are correct, after cotton is bleached using hydrogen peroxide, the peroxide itself decomposes into water and oxygen, after which the water evaporates leaving nothing but dry, white cotton fibers behind. Therefore there is no peroxide to "boil out" of cotton balls.
I guess as long as one is using "100% pure cotton" i.e. cotton balls, or the roll of "sterile cotton" from CVS, no boiling would be required. Corrrect?
Now, something that contains some kind of sizing on the other hand would have to be boiled to remove this sizing. That to me would mean some kind of yarn, twine, or cheesecloth, or gauze.
Someone please correct me if I'm wrong anywhere here, as that last thing any of us want to do is spread any type of misinformation.
