How do I know it's time to clean/replace the atomizer?

Are there any telltale signs I can look for?

Really bad taste - time to clean
No vape - time to replace

If you're not getting any vapor the first thing you check is to see if you've flooded the atty - remove and blow out from the batt(threaded) end into a paper towel on the cart end. Then put a drop or 2 on the atty bridge and try again. Now if you're not getting much vapor then clean it - I suggest 151 vodka (or everclear if you can get it) soak for a 1/2 hour, blow out, dry and again two drops in the atty and huff it abit - like trying to keep fire on a pipe or cigar. Bad harsh taste would be another indicator IF you haven't run out of juice which will also give you a harsh taste.
