whats with all the boiling??? what could be in the cotton that requires it to be boiled for 15 minutes and who came up with that time limit? Why wouldnt 12 minutes work, maybe 15 is too short and it should be boiled for 45 minutes. It seems to me that by boiling cotton you reduce the water in the pot and increase the chemicals that are in the water percentage wise per volume of water, plus what ever you are trying to get out of the cotton is still on the cotton since its sitting in that water. And if you rinse it, arent you just running the same type of water thru it as what you boiled in in minus "whatever was in the cotton"? As far as hydrogen peroxide, it is safe, you use it on cuts etc. Besides it turns into oxygen and water when it breaks down... yes it breaks down into O2 and H2O. Thats why hydrogen peroxide is stored in brown bottles, so it wont break down while being stored.
