I basically vape two types of liquid, a fruity dessert, and a bakery type...when I am wanting to switch from one to the other I disassemble and clean the whole thing with water...except the coil. The coil I wipe clean and then I take a new paper towel and roll up a corner and insert it in the hole in the coil...then I tightly wrap the whole coil in the rest of the paper towel and Velcro it tightly in place and let it set until I am ready to switch back. I was surprised the first time how much of the remaining juice the paper towel sucked out. It leaves an almost completely juice free coil and no fear of ruining it with a dry burn.
