For the best performance from your VOOPOO vape tanks, regular cleaning is a must. Start by emptying your tank of any e-liquid. Disassemble your tank and rinse the parts under warm running water to remove any leftover e-liquid. For tougher residue, use a bit of alcohol or a few drops of soap. After rinsing, dry the parts with a paper towel and let them air dry for 10-15 minutes. Once everything is dry, reassemble your tank and refill it with fresh e-liquid. As a general guide, you should aim to clean your tank once a week and replace the coil regularly to keep your vaping experience smooth and enjoyable.
