Screen Door Care and MaintenanceCleaning. Dust and dirt build up in screens over time, so you'll need to clean yours every so often. Rub the screen gently with a soft brush to loosen dirt and debris, then use a handheld vacuum cleaner or attachment to siphon it off. Wipe the solid components of the door with a cleanser appropriate to the surface (painted wood, metal etc.). Lubricating. Oil the hinges periodically with WD-40 or another lubricant to keep them operating smoothly — unless, of course, you prefer your door to creak and squeak. Patching. Screens are prone to snags and rips, and they can come loose from their framing. You may be able to fix small holes yourself using a patch kit or other supplies from your local home center or hardware store, but major damage calls for professional help.More:Screen Doors Can Mesh With Any StyleSusan Wallace Turns Screen Doors Into Art
