Cleaning the DaVinci IQ2 Carbon is a long exercise, but it is what it is. A technically superior device tends to have a tricky cleaning process, especially due to the different compartments and components. You need to remove the mouthpiece and then the gasket from it.
Next, remove the flavor chamber, aka glass vapor path, from the device. Clean the flavor chamber and the mouthpiece with alcohol wipes. Also, use a brush and an alcohol-dipped earbud to clean the chamber.
An alcohol pad is ideal for cleaning the pearl and other accessible portions. For the exterior, use a soft and wet cloth to wipe it. Once the cleaning is done, burn the impurities by heating the empty chamber at the highest intensity for a couple of minutes.
