The cart was full of liquid, I had just topped it up.
It is possible a fibre or two burned... looking at the cart the there are a few bright white spots showing which I dont recall seeing before. Possibly melted fibres.
I've washed and refilled the cart as the liquid smelled burnt, but I dont see a way of cleaning the atomizer so hopefully a few drips and a bit of puffing will get through the bad taste.
Unfortunatley I dont have a spare cart with me as I'm stuck at work
