There’s a few bits to do here - some you’ll want to do more regularly than others but none of them take a long time and all will help ensure you get the best out of your kit. Let’s start at the top down:
The drip tip: the little bit of the vape you put in your mouth to puff on. The way they’re designed means they can collect a bit of condensation as you vape. To keep it nice and clean, it’s as simple as getting some tissue or a cotton bud and just wiping the inside now and again.
The tank itself: the glass cylinder, chimney and base all get covered in e-liquid when you fill the tank up. As such, it’s a good idea to give them a little clean now and again. Because your liquid is flavoured and sticky it can leave a bit of residue on these parts it’s a good idea to wash them when you change flavour variety (for example if you go from menthol to fruit). What’s the best way?
Disassemble the tank completely and break it down into its component parts (a good idea to do this when you want to change the coil too so everything is fresh).
Give it a wipe down with some tissue to get the worst of the remaining liquid off, then get a bowl with some warm water and dishwashing liquid and put the chimney, glass and base in there.
Swish each of them around a bit, then a scrub with an old toothbrush if you have one handy. This helps get into all the little nooks and crannies.
Take them out of the water and give them a rinse. Pat dry as much as you can with some kitchen roll and leave them to air dry completely overnight. (This is when you need a backup vape to keep you going while your other one dries).
Finally - the battery terminal: keeping your battery terminal clean is important, it’s what connects your tank to its power source so if it’s grubby it can affect performance. Whether it’s just a bit dusty or maybe your tank leaked a little e-liquid, give it a wipe with a cotton bud now and again to keep it clear.
