i also use fdd'ed method for cleaning.. and with that bong.. just find something to plug up the carbs with and any other holes that the alcohol may leak from.. with one that big your best bet me be sitting it in the tub or a big laundry sink or something along those lines... fill it with as much alcohol as you can and just let it soak overnite or however long... after it soaks for awhile, do the shake that fdd'ed said.. the resin should just come running out... if it is too big to clean all at once, try to break the process down to a few steps, like get one area clean first, then move onto another area and so forth.. it may take a few days to get her all clean, but your taste glands will love you for it..
