To keep your Clamshell Base looking its best, clean regularly with a soft cloth, mild soap, and water. Rinse thoroughly and allow it to air dry before use or storage. Avoid abrasive cleaners, harsh chemicals, and prolonged exposure to standing water, as these may damage the finish. Periodically inspect all hardware and tighten if needed to ensure continued stability. When not in use for extended periods, store the base in a clean, dry location or cover it to help protect it from the elements and extend its lifespan.
