after reading this thread yesterday i decided to clean my pipe ive had it for over a year and have only been scraping out the bowl once in a while. i took a freezer bag and pourd like 1/2 inch of rubbing alcohol and a teaspoon of salt heated in in the microwave for 10 seconds to get it very warm and place my pipe in the bag and ziped it shut and shook it for a few minutes, instantly the mixture turned dark brown. i did this 3 time and the pipe was totally clean, i then boiled it in pot of water and it lookes brand new. cause of the bag there was no mess and i didnt have to cover the carb, bowl and mouth piece.
