My wife & I have been vaping for about 2 months, and our equipment is fairly simple: Unique 901t e-cigs with 901t atomizers & .9ml tanks. For cleaning I'm currently using W2V's Atomizer Refresher, which smells vaguely of denatured alcohol and might have a little VG or PG in it, not sure. Works very good but with two heavy vapers in the house it's getting pricey buying it online. What do you guys use or recommend for keeping your attys clean?
