Grab a paper towel or a lint-free cloth. Dry the mouthpiece and the air intake slots gently — don't push anything inside. Then set the vape upright on a flat surface, away from heat or sunlight. Leave it for 15–20 minutes.

If it's a refillable model like the LINQ-PRO, check that the mouthpiece is screwed on tight. And if you recently refilled, you might have overfilled — wipe the excess and close it again. That's usually the fix.
