Once a week, go a step further. If your device has a removable mouthpiece (check your manual), take it off and rinse it with warm water, then dry it completely before reattaching. If it's not removable, use a slightly damp cloth—wring it out well—to wipe the mouthpiece and any visible residue.

For the airpath, use a dry cotton swab to gently clean the channel inside the mouthpiece base. You're trying to clear any buildup that's narrowing the airflow. Less airflow means weaker vapor and muted flavor.

Also, check the battery contacts if your device has any visible ones. A dry wipe with a cotton swab keeps the connection clean, which helps consistent power delivery.
