To clean a glass pipe effectively, the most popular and recommended method involves using isopropyl alcohol and coarse salt. The process is as follows:
- Fill the pipe with about a teaspoon of coarse salt per four inches of pipe, then add isopropyl alcohol until the pipe is almost full.
- Plug the holes of the pipe with your fingers and shake it vigorously for up to 2 minutes to dislodge resin and debris.
- Pour out the mixture and check the cleanliness; repeat shaking if necessary.
- For stubborn buildup, soak the pipe in isopropyl alcohol (preferably 91% or higher) for several hours or overnight.
- After soaking, use cotton swabs or pipe cleaners to remove any remaining residue.
- Rinse the pipe thoroughly under warm water and allow it to dry completely before use.
Other methods include using baking soda and vinegar, boiling water, or commercial pipe cleaning solutions. Avoid harsh chemicals, boiling water directly on glass to prevent cracking, or rough scrubbing tools that may damage the glass. This process not only restores the pipe's appearance but improves the taste and smell during use. Regular cleaning is recommended, especially when resin buildup begins to affect performance.
