For basic cleaning, we recommend using our G Cleaning Tips, which come filled with a cleaning solution. If deeper cleaning is required, you can also use your G Tool to remove more solid residue. For the deepest cleaning, you can soak your mouthpiece in isopropyl alcohol for about 20-30 minutes, followed by thoroughly rinsing it with hot water. This should loosen and dislodge even the toughest built up residue.
If you have any further questions please contact our Customer Service Department, which is available Monday through Friday, 8:00am to 5:00pm PST.
