How to clean a dirty outdoor sun umbrella? Here are the specific methods:
1. If the umbrella surface is dirty, you can use a soft-bristled brush dipped in clean water to gently scrub it. Do not rub it with your hands, and do not wash it too frequently, otherwise it will affect the sun protection effect.
2. When cleaning, use gentle and even pressure. Do not scrub vigorously to avoid damaging the threads or brushing off the patterns and decorative parts of the umbrella.
3. For colored canvas, avoid contact with items that are difficult to clean, such as carbon ink. After cleaning the canvas of this color, apply toothpaste or white chalk powder evenly, and then let it air dry to prevent discoloration. Alternatively, place two clean white sheets of paper over the umbrella, let it dry, and then peel them off. This will also prevent discoloration.
4. Make a cleaning solution for the sun umbrella. The cleaning solution only requires white vinegar and detergent. It is important to choose a detergent that is not alkaline. Also, prepare a disposable paper cup.
5. When brushing, brush along the length of the umbrella frame, and maintain a consistent direction. Do not brush vertically and horizontally alternately, as this will damage the sun protection layer of the umbrella.
6. After washing, let it air dry naturally in a well-ventilated, shady place. Do not expose it to direct sunlight or high temperatures to prevent the adhesive from peeling off or fading, and to avoid accelerating aging.
