First you will need a glass piece

Some rubbing alcohol

Baggie of salt. Just enough salt to work through the piece.

Put the piece in the baggie on top of the salt

Then add the rubbing alcohol till it gets just about to the top of the bowl.

then shake and shake and shake. You might want to put it in another bag just in case of leaks.

Shake for about a good 5 minutes.

Once you can see most of the resin is off take it out and rinse in warm water

Now if there is any resin left like mine at the bottom of the piece then get a q-tip and stick it through the carb.

After that your piece/pipe should be resin free and look like you just bought it!
