hey mate welcom to the forums. just a few guidelines you might wanna follow, saves people alot of time and stops clogging of the forums. try asking all your questions in one thread, rather than making 3. if there simple extraction questions post em in the sticky up the top.     - just find something which is 100% naoh or sodium hydroxide. doesnt have to be red devil, but red devil is popular cause its easily availabe to usa and is 100% naoh. go to the hardware store and look for caustic soda
