Are you tired of smoking a bowl that has three inches of black smelly resin covering it?Tired of looking at your beautiful bong with weird brown stains from the bong water?
Have a vapor whip (tube) that is yellow and dirty?
There is a SIMPLE CHEAP way to solve these problems.Purchase a bottle of rubbing alcohol 70% works fine but the 90 or 99% ones work best.
Get your bowl, pipe, bong, vapor tube, whatever, and first get the bulk of the shit out by putting it under a stream of hot water from the faucet, or you can put your piece into a pot and boil it for a few minutes to help loosen up the resin.
After you have exhausted the hot water trick this is where the alcohol kicks ass.
Just pour some into your bong or bowl or tube. Cover whatever holes are open and shake the shit out of it. Adding salt helps a great deal as well because it works as an abrasive and helps rub off the gross resin.
The alcohol should quickly turn yellow or even brown depending on how dirty you piece is.
This process may need to be repeated up to five times, depending on how clean you want your piece and how dirty it is.
Cleaning your pieces regularly is a very good idea, because a bowl covered in black resin is going to ruin the taste of the pot you are smoking and also you are going to end up smoking some of that resin which is GROSS

I hope this is new information for some of you, and i hope it helps!!
