Give it a nice shake and seal the Ziploc bag, “burping” it to let out the air. Once the pipe and salt are in the Ziploc bag, add enough alcohol to fully submerge the pipe. The point of the salt is to work as an agitator to dislodge resin where a pipe cleaner or other tools can’t reach. You can either take the pipe and put it in the bag and add a teaspoon or more of salt, or take some of the salt and add some directly into the bowl and stem of the pipe, before dumping the rest in the bag. You can go two different ways with this step. Take the pipe and wash it under the faucet in your sink to get out any ash or bits of weed that haven’t yet bonded with the resin Step 2: Place the pipe in a plastic bag and add salt (Shutterstock) Step 1: Give the pipe a good rinse Glass pipes can fill up with resin and ash that can gunk up the works and leave the glasswork looking like an asphalt spill.
