Maintenance knowledge of umbrella:

1. After using the umbrella, do not fold it with water. You should open the umbrella and place it in a ventilated and dry place to dry (you can also use a soft cloth to dry the inner and outer ribs and umbrella surface). After a period of time, a small amount of lubricating oil can be applied to the umbrella ribs and umbrella handle to prevent rust and mold. Do not put the umbrella upside down, it is not easy to dry, and the umbrella head will be easily corrupted if it is soaked for too long.

2. Before opening the umbrella, shake the umbrella surface, straighten the ribs, and then slowly open it to prevent breakage. For ordinary umbrellas (non-windproof ribs), try to avoid using them in strong winds, so as not to bend the ribs.

3. Don't pick up things with an umbrella, don't use an umbrella as a walking stick, and keep the umbrella away from high temperature, which can prevent the umbrella from deforming.

Fourth, the new umbrella should not be left unused for a long time, so as to avoid brittleness and deterioration due to long storage.

5. After wiping the umbrella clean, let it dry, put it at room temperature for a while, and then put it away. Do not put it away in the sun. This will easily make the umbrella surface aging, brittle and easy to rot. Try not to expose it to the sun. If you accidentally get dirty, you must wipe it off in time. Don't wait for a long time to wipe it. This is not easy to wipe off, and it is not good for the maintenance of the umbrella, which will shorten the life of the umbrella.
