dude okay heres what you do: (it requires boiling or extremley hot water but you dont gotta actually boil the bowl)

either loop a wire through your bowl so that you can hold the wire with the bowl hanging down, or get tweesers that youn can succesfullly grasp the bowl with.(the point is so that you can dip the bowl into a mug of hot water without burning your hand

then, either boil water in a teakettle like your just making tea, or if you dont usually make tea and it looks suspecious, you can just turn the sink on hot until its as hot as can be.

fill a mug with the hottest water you can get, and then using the wire or tweesers, swish the bowl vigourousley around in the water. if the water starts getting cold, refill the mug with the hot water. but be sure you collect the resin first. the mug will fill with the resin and you should ewither pour it out over thick layers of paper towels or a screen or coffe filters to catch the resin. once you've gotten as much resin that will come out, try and collect the rest with a paper clip or wahter(there might not even be any left)

now you can fill a mug with rubbing alchoal and swish the bowl around in that to make it extra clean and shiny. (if you do, be sure to rinse it througley in water after)

ive found q-tips are perfect to dry out the inside of your bowl when your done
