"We recently purchased several atomizers since it seems they have a limited amount of life, especially when we use a thicker higher vapping liquid. I decided that after trying to clean the units according to standard protocol, that I would try something that a chemist friend of mine suggested. We now are submerging them in a small tube of pure alcohol, (Everclear) surrounded be a small amount of cotton to keep the atomizer coil from touching anything hard. After 24 hours of sitting, there is a small accumulation of particulate in the cotton. I don't know how long or how many times I will be able to do this, but, it is at least doubling the life of our atomizers. Love Prosmoke, love the equipment, and telling anyone who will listen that this is the wave of the future. Thanks Prosmoke for a great product"
