Doing some cleaning and replacing coils on my iClear tonight and I used a q-tip to clean the drip tip. I didnt see it while I was cleaning it until I pulled out the q-tip and noticed a green residue coming off. It was right inside the tube of the tip where my mouth meets around the air hole. Kind of confused what would be causing this unless I'm turning into the Hulk. I'm assuming its some kind of copper reaction from my skin or the drip tip or the juice. I've been vaping Halo Twisted Java which is clear. I'm not too alarmed by it being only a small amount. Is the drip tip on the iClear chrome plated brass? The tip is not rubbed off anywhere.
