Ya I've tried boiling it a couple times. I think I didn't boil it long enough ause there was still resin left in the bottom of the bowl. Also boiling it will make your kitchen smell like resin. so if you are expecting your parents to come home soon i wouldnt boil it. Also with the chemical cleaners and stuff, they should work great just make sure to run a lot of hot water through your pipe afterwards to get the chemicals and shit out.
