If I wanted to switch flavors in my dripper, how would I do so without cross contamination ? Do I clean the wick ? Flush it with water?
I usually just vape out the old flavor as much as possible, then drip the new flavor. I'll put just a couple of drops of the new flavor onto the deck (not directly onto the wick or coil), vape out as much as possible, and repeat. This quickly gets rid of the old flavor, after doing this two or three times, the old flavor is pretty much completely gone.
Don't be afraid to mix flavors -- I've stumbled upon to some great combinations when switching flavors without rewicking. Pretty much the only time I will rewick when changing flavors is to go from a very strong flavor to a much more subtle flavor.
