Wait for a day with good weather and remove your insect screen from the window. Lest the room will be stained, you'd better clean the screen outdoors. If space is limited, you can also do the cleaning in the bathroom (lavatory) (See Figure 1).
Use your garden hose or hand-held shower to rinse both sides of the insect screen as thoroughly as possible, in order to remove loose dirt, dust, and visible debris (See Figure 2).
Figure 1: Because of the limited space, we choose to do the cleaning in the bathroom.
Figure 2: Using the hand-held shower to rinse screen is an important step to clean it, especially for anti-pollen window screen and anti-dust window screen.
Mix 1/4 cup of liquid all-purpose cleaner with 1/2 gallon of water in a plastic basin. Then, dip your scrubbing brush into the solution, and start scrubbing the screen in small circles, from top to bottom. Remember to rinse the brush in clean water regularly.

Figure 4: A brush is needed to scrub the screen and scumming form.
Use your garden hose or hand-held shower to spray off both sides entirely and give the screen a final rinse. Be sure to rinse thoroughly because any soap residue left behind will attract more dust and dirt making it more difficult to clean the insect screen next time.

Shake the screen to remove excess water. After that, use a dry towel to absorb remaining water on the screen, and lean it against the wall until it is completely dry.
