Using your 13' yellow round polyester market patio umbrella is super easy. First, since it doesn't come with a stand, make sure you have a proper stand ready to hold it firmly. Then, use the manual lift to open the umbrella. It's a simple process, just pull up gently until it's fully open. To close it, do the opposite. When using it outdoors, keep in mind that while it's weather - resistant, in extremely strong winds, it's a good idea to close it to avoid any damage. As for maintenance, you can clean the polyester canopy with a mild soap and water solution. Just wipe it down gently and let it dry completely. The aluminum ribs are durable, but you can check them occasionally for any signs of wear or damage. That way, your umbrella will stay in great shape for many outdoor parties and sunny days.
