it is not necessary, do not clean the umbrella. If it must be cleaned, it is better to wash the umbrella surface with water. In fact, the best way is not to buy a light shade umbrella, so you don't have to work hard. And I heard that dark shade umbrella has better UV protection function than light shade umbrella! Wine red and dark green are good choices.
Make a cleaning solution for the sunshade. As long as white vinegar and detergent can be used as cleaning solution, it is necessary to select detergent without alkali. Prepare another disposable paper cup. When the materials are ready, the work will begin immediately. First of all, the detergent is put into the disposable paper cup, as long as the detergent does not pass the bottom of the paper cup. Next is white vinegar. Pour half of it into the glass.
Remember it's half a cup, and the other half needs 40 degrees of warm water to fill it. Pour 40 ℃ warm water into the cup. Warm water serves for white vinegar and detergent. Only with warm water can they fully integrate and become more powerful. Make up the detergent. We can dip a towel in the detergent to wipe the sunshade. We also need to remind you that when you do this, you should wipe along the umbrella frame longitudinally, and keep the same direction. You can't wipe vertically or horizontally for a while. That would destroy the sunscreen of the umbrella.
In addition, we choose detergent without alkali, because such detergent can not only wash off the stains on the umbrella, but also won't hurt the sunscreen layer of the umbrella. White vinegar, which can keep the original luster of the umbrella fabric, plus 40 degree warm water mixed with detergent and white vinegar, has no effect on decontamination. After the surface of the umbrella is brushed, we need to wash it with clean water.
Remember to wash thoroughly, or the surface will leave traces of detergent after the umbrella is dried, which is very ugly. Next, dry the umbrella in the shade. By contrast, the effect is obvious. This method can not only clean the sunshade, but also won't hurt the sunshade. You might as well try it.
