How to clean the Yocan Evolve Plus XL Concentrate Vape Pen?
Thanks @vapevetstore

Usually, cleaning concentrate vape pens are never easy.
If you want to keep the Yocan Evolve Plus XL clean, you must make sure to burn off the concentrate residue in your concentrate atomizer after every vape session.

The best way to burn off the residue is by repeatedly heating your vape pen and lightly blowing on the quartz coil. You could also use a Q-TIP to clean the walls of the heating chamber.
Make sure the vape coils are hot when using the Q-TIP.
If the coils are not hot, the walls will be sticky, thus, making it difficult to clean.

What I find that works will to clean the last remnants from the coils is I remove the lid, and gently suck in while the power is on.
You get a wicked hit or two. You can look down the mouth piece and when all coils be glowing, time to reload.
