Mosquito nets for windows are made in a special frame with handles by which you can hold them to remove them. But they are short-lived and often break, so it becomes difficult to remove the mesh without such handles. You can use a women's invisible hairpin.
How to safely remove the mesh from a plastic window without damaging it
Some people recommend using paper clips, but they are made of soft metal: they bend easily and the mesh can easily fly out.
Using bobby pins is better because they are more elastic and hold their shape. A small part needs to be bent into the shape of a hook, and its long part will act as a handle.
The hook must be threaded under the crossbar on the mesh frame. This will help lift it from its mounts, hold it comfortably and remove it from the window.
You can wash the mesh in a simple bath with shower. It will be enough to simply spill it with water and wash off the dust and cobwebs. While the mesh is draining, there is time to work on the windows: you need to fill a bucket with water and use a special mop with a rubber scraper to wash the windows.With the help of a long handle on a mop, you can do this job quickly and safely.
Once the screen and window are cleaned, it can be placed back on the window frame. It is better to get homemade handles so that they do not damage the mesh or scratch the window.
