- Fabric Care: Curtains and netting can be spot cleaned with mild soap and water. For deeper cleaning, follow fabric care instructions on the labels. Ensure they are completely dry before storing to prevent mildew.
- Seasonal Inspection: Periodically check all bolts and screws to ensure they remain tight. Inspect the roof panels and frame for any signs of wear or damage.
- Winter Care: While the galvanized steel roof is designed to withstand snow, it is advisable to clear heavy snow accumulation to prevent structural stress.
