Above is a step-by-step tutorial on how to clean your Firefly vaporizer. The total run time is only 4 minutes. This is a video for the OG Firefly and not the new Firefly 2 + but still works.
UPDATE: The new Firefly 2+ is out now and I really like it. Check out my Firefly 2+ Vaporizer review for more info. The cleaning process for the new version is basically the same. All you really need is some ISO and some paper towels. Just be sure to keep the vape upside down when you are cleaning out the bowl and only use a little bit of ISO on the paper towel. Be sure to check the screen on the mouthpiece as well. That tends to get dirty quickly and will drastically reduce draw resistance.
