What should I use to clean my security door (or my screens)?
The best way to clean the door is with a mild cleaner like Windex. Spray it on and wipe it down completely. To clean the screens use a soft brush attachment to your vacuum cleaner or use a damp cloth and clean both sides. Hosing down, or spraying the door or screens with water is not recommended. If you use a water hose be sure the pressure is VERY light, and completely wipe off the excess water. High pressure can push the screens out of the rubber spline that holds them taut in their frames. Water creates rust, and rust is the enemy of a steel door.
