Using these double iron doors is simple. Just install them using the provided hardware and frame. When opening and closing, do it gently to avoid damage. For daily use, keep them clean by wiping with a soft cloth. Avoid using abrasive cleaners that could scratch the surface. If you live in an area with harsh weather, check the weather stripping regularly to ensure it's in good condition. Every few months, you can apply a light coat of wax to protect the iron and keep it looking new.
