7. Maintenance
- Frame Cleaning: The aluminum frame has a thick powder coating that resists scratching, peeling, corrosion, and rust. Clean the frame periodically with a mild soap solution and water. Rinse thoroughly and dry with a soft cloth. Avoid abrasive cleaners or harsh chemicals.
- Roof Cleaning: The polycarbonate roof can be cleaned with a soft brush or cloth, mild soap, and water. Rinse well. Avoid using high-pressure washers directly on the panels.
- Curtains and Netting: Detachable polyester curtains and netting can be machine washed on a gentle cycle with cold water and mild detergent, or hand washed. Air dry only; do not tumble dry.
- Seasonal Inspection: Regularly inspect all bolts, screws, and connections to ensure they are tight. Re-tighten as necessary. Check the anchoring points for security.
- Snow Removal: While the gazebo can withstand up to 4 inches of snow, it is recommended to remove heavy snow accumulation promptly to prevent excessive stress on the structure.
- Severe Weather: In anticipation of strong winds or heavy storms, it is advisable to remove the curtains and netting to reduce wind resistance and prevent damage.
