So yeah ... I have my Billow v2 nano, but lately, I have been itching to clean it out. Reason is that lately, there is a weird metallic after taste when I vape.
I know it's not blood (no saltiness, just plain metallic taste), its not my juice (tried different juices and even made a fresh batch of DIY juice from newly-opened VG/PG and flavors and mixing bottle) ... but the taste is still there, even after changing my coils and wicks.
So my question is, how often should I be cleaning my RTA? And what are the things I should be watching for during the cleaning process?
Edit: are there other possibilities for the taste?
