1. After the umbrella has been used, it should be placed in a ventilated and dry place to open and dry, and a small amount of lubricating oil should be applied to the ribs and handle to prevent rust and mold.
2. Before opening the umbrella, you should loosen the umbrella surface, straighten the ribs, and then slowly open it to prevent breakage. If the PVC fabric umbrella sticks together, do not stretch it hard. The place is separated by hand and then slowly opened.
3. Do not hang the umbrella on the alkaline lime wall to prevent the umbrella from becoming brittle.
4. Do not use umbrellas to pick things, do not use umbrellas as a walking stick, and do not let the umbrellas approach high temperature (especially transparent umbrellas of plastic fabric) to prevent deformation of the umbrella.
