You use an empty bottle to start with, then you leave the valve open for a few days, then apparently you slowly unscrew the valve assy from the bottle and leave it air some more. then you fill the gas bottle with water for a few days, empty and refill then cut the thing open with the water still inside with a grinder. ALL CAVEATS APPLY there is videos on You Tube showing you what to do.
