Atomizer - I use white vinegar. Soak for several hours, rinse under hot water, and let dry overnight. If this doesn't get all of the flavor out, go to wal-mart and
buy a bottle of VG. It is found with the band-aids. Make sure the lable has USP on it. Drip a couple of drops on the dry atomizer and
vape it until gone.
Cartridges - Remove the filler with tweezers. Rinse under hot water. Wrap in paper towel and blot dry. With the plastic part, rinse under hot water, then use a Q-tip to dry it. Replace filler with the tweezers, fill and enjoy.
Some people
throw the filler out and use Marineland Type U to refill. Here is a thread about it. I do mine this way and it works wonders.
