What is the best way to clean and maintain the G Pen Elite II Mouthpiece?

First ensure that your device is powered off and cooled down. Then soak a cotton swab with ISO, making sure to squeeze out any excess before applying to your device. Swab all around the Silicone Insert and over the screen. Remove silicone insert and swab the interior walls and air flow hole of the mouthpiece. For an even deeper clean, remove the screen from the silicone insert and remove the spiral ceramic air path that sits above that. Soak all three components of the insert along with the outer zirconia mouthpiece in ISO. Remove from ISO, rinse thoroughly with water, and let air-dry. Assemble all components of the insert and mouthpiece and activate a session at maximum temp to burn off any residual ISO.
