A. To clean the coils effectively, first, ensure the device is turned off and cooled down. Use a soft brush or a cotton swab dipped in isopropyl alcohol to gently scrub the coils. Avoid using excessive force to prevent damage. After cleaning, let the coils dry completely before using the device again.

B. Consider using a specialized cleaning solution designed for vaporizers. These solutions can help break down residue more effectively than alcohol alone. Follow the manufacturer's instructions for use, and ensure that all parts are thoroughly rinsed and dried before reassembling the device.
