1. Remove the cartomizer from the battery.
2. Unscrew the mouthpiece and fill the cartomizer about half way with water.
3. Screw the mouthpiece back on and shake for about ten seconds, then unscrew the mouthpiece and empty the water out of the cartomizer tank.
4. Repeat steps 2 and 3 about five times.
5. Unscrew the mouthpiece and fill the cartomizer to the top (or fill your mouth with water) and blow water through the center tube. This will rinse off the wick where it goes through the atomizer coils.
6. Repeat step 5 about five times, then replace the mouthpiece and blow through the cartomizer a few times using a tissue to catch the water blown out of the cartomizer. This will get most of the water off the wick where it goes through the atomizer coils.
7. Screw the cartomizer back on to the battery, press the button, and draw about ten long puffs (you probably won't get any vapor).
8. Remove the cartomizer from the battery.
9. Blow through the cartomizer a few times to dry-off the atomizer wick where it goes through the atomizer coils.
10. Fill with your favorite e-liquid.
11. While the cartomizer is off the battery, use a tissue to clean out the battery contacts. This will clean out any e-liquid or dirt that has accumulated around the battery contacts.
12. Screw the refilled cartomizer onto the battery and you're back to thick and fluffy vapor in about 10 draws.
