Within the heating chamber of your G Pen Ground Material Tank, the coil itself works to clean itself by clearing off any residue that comes in contact with it. We don’t recommend using any type of liquid cleaning agent in the G Pen Ground Material Tank, as doing so could cause it to malfunction. You can use the included cleaning brush and G Tool to remove residue from the area around the coil itself and the surrounding glass sleeve, but be very careful not to be too rough with the coil itself, as too much force applied can damage it.
If you have any further questions, our customer service hours are 9:30 to 18:00 CET.
