Unclogging a Vape cartridge is an easy task. However, it is crucial to determine the cause of clogging. The most typical cause of clogging is the accumulation of oil residues. Use a sharp object to remove the oil, melt it or clean the cartridge with warm water. Loosen the cartridge to ensure that it does not block the air holes. You can also preheat thicker oils before smoking. Also, dislodge the mouthpiece to ensure it is not clogged. Finally, open the air holes to ensure that you inhale at ease.
