It wont mess anything up? cotton coils, etc.? If i get water into the mail hole opening? not just the slot i put the liquid in?
Same here unless the coil head is shot (or the RBA head needs a new wick). I've even come up with a new recipe or three that way.I just pour in the new liquid. I don't even wipe out the tank. I've stumbled across some interesting flavor combos that way. Mocha and non citrus fruit tastes surprisingly good.
There is still some degradation of performance, correct? I like the idea. 2 pack of Uwell Valyrian coils are $10!You can clean and to some degree revive coil heads by soaking them in a high proof grain alcohol like Everclear for a couple of hours, then rinsing with water, pat it dry as possible and then set aside to dry completely.
If you don't mind a little mixing of flavor you can just rinse the tank and refill and not worry about the coil. The mix taste should go away semi-quickly unless the first flavor was really strong.
