We recommend cleaning the glass stem as often as possible to maintain the best taste from your E-nano. This is easy to do. Simply put the glass back into the original plastic tube that the glass came packaged in (if applicable), and pour 70-90% iso-alcohol (available at any drug store or super market) into the container. Again, be careful not to get any alcohol on wooden portion of the E-Nano itself. Put the top back on and soak the stem until it’s clean. (15-20 minutes should be fine)
Rinse the stem with water, dry, and you’re ready for your next session.
The more often you clean the better the taste.
You can purchase replacement tubes here. If your stem or GonG adapter did not come in a plastic tube you can use a plastic sealing bag.
