I use a 10ml bottle, the kind the ejuice comes in filled with vodka, I then turn the atomizer at a 30 degree angle down so the heating coil is pointing into the sink. I then use the 10ml bottle to squirt a jet of vodka into the heating element. The vodka rinses the remnants of the old ejuice off the heating element. You can blow it out or lightly tap it with the heating element facing down onto a towel. I then prime it with the ejuice I am going to vape, just a drop or two then insert the cart and start vaping. Priming it helps the heating coil from burning up. And now I only get the flavor ejuice I just changed to.
That help?
