You can if you want to. We recommend rinsing the mouthpiece in clean water and letting it air dry from time to time. Other cleaning is completely up to you. You can disassemble the whole tank by hand and rinse it in water. You can use mild dish soap and wash it by hand if you feel that it’s necessary. Be mindful not to scratch the finish. Don’t use anything abrasive. Let it air dry.
The atomizers cannot be cleaned. They should be discarded when you feel that they no longer provide a satisfying vaping experience.
