7. Maintenance
- Cleaning: Regularly clean the light tube and suction cups to prevent algae buildup and maintain optimal light output and adhesion. Unplug the light before cleaning. Use a soft cloth and fresh water. Do not use abrasive cleaners or solvents.
- Suction Cup Care: If suction cups lose their grip, clean them thoroughly and the glass surface. Applying a thin layer of petroleum jelly to the suction cups can sometimes improve adhesion.
- Inspection: Periodically inspect the power cord and light tube for any signs of damage. If damage is found, discontinue use immediately.
