At the end of the day, give your vaporizer a quick clean. Unscrew the mouthpiece and wipe it with a dry cloth or a cotton swab. Check the connection point where the cartridge screws in—any residue there can mess with the connection. A dry brush can help get into crevices.

Store the device upright. If you're carrying it in a pocket or bag, make sure it won't get crushed. Extreme heat or cold can mess with the battery and the cartridge, so avoid leaving it in a car on a hot day or in a freezing backpack overnight.
