Do you ever get oil stuck to the top of your vape cartridge? The lonely, stationary droplets, seemingly trapped from your consumption pleasure. This happens a lot, particularly with thicker extractions. Place the vape device upright between your flat palms. Rub your hands back and forth together, kind of like starting a fire with a stick. The heat and friction will warm the
concentrate enough to travel downward to the wicking hole. Happy vaping!
