Depends on the pipe imo, smaller ones, or ones with crazy tubes are easier to clean by boiling. All my bigger pieces get the alcohol/salt treatment, takes less than a minute and youre good to gomy methods better
not really? i boiled the bowl from my bong as well as a diffuser both covered in resin and it really didnt smell that bad. i turned the fan on from the microwave thats right above the stove and that seemed to take care of most of it. i will agree that there will be some smell but i dont think its enough to worry about. just spray some fabreeze.if you boil it.. its gonna STINK!
