i just heat the resin in the pipe for a few seconds with a lighter, then take a pocket knife, usually the ones that come in utility knives work the best because they are smaller and the curves are usually more compact making them better at scraping bowls. thats pretty much it, then i throw the resin in the vaporizer and vape it. it works perfectly. and if you want the bowl section to be cleaned too, then some q-tips and rubbing alcohol + a little elbow grease never hurt a bowl.
