What is the best way to clean the new metal and glass atomizers, that have a metal coil? I just got one that you can change out the metal coil. But I will be vaping using only VG, so it will need to be cleaned a few before I replace it. The Vape shops say use Everclear (expensive), rubbing alcohol, or vinegar, and one guy told me put an Alcaselcer table in hot water with the atomizer. I will be boiling the atomizer after cleaning, so it sterilize it. What is the best way you clean your Atomizer? Some of the suggestions of cleaners did not sound healthy??
