Happens to me with the thicker juices. They run down the inside so slow you think you are safe and then after the molasses like
juice finally all settles, Oops... Get some standard pipe cleaners and very gently insert one in the air hole from the battery end and when you feel it touch the coil/wick assembly STOP. then just spin it a little while removing it and all of the over fill will be gone and you're back in business. Works like a charm...
