Has anyone figured out why the unused juice turns so dark? I thought it was due to a dirty atty, but I just got 2 new attys, loaded one up, vaped for 1 day, and now the juice gets dark at the empty tank stage. Are we gonna have to clean these daily? I only use good, clean, clear liquid, pg, to be exact. I hate to say it, but I'm not overly impressed yet. rsmith76
Juice gets dark from the heat the atomizer produces. Take a little bit of juice and leave it out in the sun for a bit and let it heat up. It will get dark pretty quick.
