i got my falcon and it is amazing, just dirty. i need to ream the bowl and follow up w/ an alcohol treatment but what is the best way of cleaning the stem? i tried running a pipe cleaner through it but met resistance so i thought i'd ask the experts (falconeer :P ). being metal i assume it can take a harsher treatment. soak in alcohol? boil? any particular method for polishing the stem after it's cleaned? thanks!
