Depends what flavors it is. You don't want a fruit flavor to mix with a deserty chocolate type flavor same with menthol or mint. If you're going fruits/candys etc you can just fill 'er right back up and vape away. I only suggest cleaning for potent flavors like chocolates and dark deserts or strong mints and menthols as they tend to linger.Originally posted by dj_rice
Thanks for the help! Will be in town during Christmas week. Hope your open, I wanna grab some juice.
As well, should I be cleaning out the tank every time I change juice or just top up with new juice is fine?
