Using this Milan square crank umbrella is easy. First, assemble it as required. Once it's set up, you can open it up to enjoy the shade during hot summer days. When you're done, simply close it down. Remember, this umbrella contains nickel compounds which can be related to cancer, so handle it with care. For maintenance, when it's not in use, store it indoors or cover it well to protect it from the elements. If there's any wooden part, keep it away from standing water. Regularly dust it with a small brush or a vacuum. If there are spills, clean them up right away with a slightly dampened sponge. And never use bleach solutions as they can damage the umbrella.
