1. Soak it in ISO
Keep soaking your coils since steeping them in alcohol will help loosen up that wax concentrates.
2. Please use a q-tip to clean the coil and the contact points.
3. Filled with lukewarm water.
Once they're cleaned, dunk them on another filled with lukewarm water.
4. Dry it completely.
Leave them out to dry. Usually leave it for half a day.
5. Re-screw it back on the Yocan Evolve Plus dab pen.
After drying out your coils, you may replace the parts back again for one final touch.
And you also can refer to the Yocan Evolve Plus user manual page.
