so i just bought this bubbler of my boy yesterday (ill post picture below) and right where the water goes theres a whole bunch of res caked to the side and i cant get it out (i wanna smoke it not dissolve it) i was hoping by you guys looking at the picture you can give me advice on how to do it. Also would taking a lighter and holding it up to where the res is caked on break it? i dont want to do that if it will break it but if it would work let me know. Thanks
