Keeping a refillable vape in top shape starts with regular cleaning. Disassemble the device and wipe down the tank and connections with a soft cloth. Replace coils as soon as flavor fades or vapor production drops, typically every one to two weeks. Avoid overfilling the tank and always use e-liquids appropriate for the device. Store the vape upright in a moderate temperature environment. Check for leaks or residue often, as these can indicate worn seals or improper assembly.
