1. Umbrella cloth contains acid after dyeing. Newly bought umbrellas must not be stored for a long time. They must be washed away by rain before they can be placed. Don't hang the umbrella on the lime wall that contains alkali to prevent the umbrella surface from becoming brittle. It is best to put the umbrella in the umbrella cover when not in use to prevent dust from sticking to it.
2. Do not fold the umbrella with water after use. Open the umbrella, dry the inner and outer umbrella poles and umbrella surface with a soft cloth, hang it upside down in a ventilated place to dry, then close the umbrella and put it away.
3. Before opening the umbrella, loosen the umbrella surface, straighten the ribs, and then slowly open it to prevent the ribs from breaking. For ordinary umbrellas, try to avoid using them in strong winds, so as not to damage the ribs of the umbrella.
4. Don't use umbrella to pick things, don't use umbrella as walking stick (except cane umbrella), keep the umbrella away from high temperature, which can prevent the umbrella from being deformed. The umbrella surface of the fabric should be prevented from splashing on soot and sparks, so as not to burn the umbrella surface. The plastic umbrella surface should be protected from sunlight to prevent the umbrella surface from aging.
