Clean the rust off as soon as possible as it will degrade the metal, weaken it and can stain your door permanently.
-
Remove your home security screen door by unscrewing the screw placed vertically in the hinges or by prying out the nail with a flat-head screwdriver. Lay the home security screen door horizontally on a concrete work surface or over a tarp on your lawn.
-
Scrape rust off any areas on the door that aren’t made of fine screen using a metal paint scraper. Don’t scrape the screen as you could damage it.
-
Brush the rust off the areas of the door not made of fine screen with a wire-bristle brush until gone. Again, don’t brush the screen, as it is fragile and could rip or bend.
-
Spray water-displacement spray on any rust growth visible on the fine-screen parts of the door. Let it sit for 10 minutes.
-
Gently scrub the screen door with a nylon-bristle brush until the rust is gone. Rinse the doors with clear water from your hose.
-
Lean the door against your home and let it dry completely before reattaching.
