Our special formula of emulsions, UV inhibitors, glossing agents, and dust repellents don't just cover the dust, it destroys it. The dust particles are organically dissolved making the screens look like new and the dust repellents help to keep them looking that way. Look at the close up below. On the left you can see the dust particles. The right side was treated with Screen Magic. You can see there are virtually no dust particles. Screen Magic works on all types of screens. Bug screens, sliding screen doors, and solar window screens of all different colors. No need to drag out the soaps and brushes. Instead of spending your time scrubbing screens, use Screen Magic. No need to rinse off the screens with water. Just remove the screen, spray it with Screen Magic and replace it. The screens will look like new.
