How to Remove Rust Stains From Windows

Metal accents around or on your windows can add a classic touch to your home. But those accents can become rusty, and the rust can drip or transfer onto the surface of your windows. Rust is a type of organic stain that should be removed promptly so it doesn't transfer from your window to yet another surface. Remove rust stains carefully so your windows aren't damaged or scratched, and tend to the metal objects nearby to prevent future rust transfer.
