Put some soda in the seat tube then add boiling water , this makes the caustic more vigourous  ;) wear safetly glasses tho . If u add 2 much soda it will just froth up and out the top . Leave the tube full 4 half a day then pour out the mixture of dissolved ally and repeat till its all gone  :daumenhoch: will take a few goes tho  ;)
