Remove Rust From A Metal Garage Door And Protect It In The Future


After you have a metal door installed on your garage, it can become rusted if it is exposed to moisture for extended amounts of time. Learn how to remove rust with the following steps and protect it from further damage with a rust inhibiting spray.

Use The Following Materials

  • sponge
  • scrub brush
  • metal cleaner
  • soapy water
  • water hose
  • hand or electric sander
  • low and fine grit sandpaper
  • tack cloth
  • vinyl tarp
  • rust inhibiting spray
  • mineral spirits
  • lint free cloth

Clean The Door

Secure the door so that it doesn't accidentally open while you are cleaning it. Remove surface dirt from the door by wiping it off with metal cleaner and a damp sponge. Follow up with soapy water. If stains are embedded in the metal, loosen them with a natural bristle scrub brush. Apply consistent pressure to the stained areas as you move the brush back and forth. Rinse the door off well with a water hose after it is clean. Wait for the surface to dry. 

Remove Rust

Remove rust spots from the door by attaching a piece of low grit sandpaper to a hand sander or electric sander and moving it across the metal surface. Press down firmly on the sander as you move it back and forth. After the rust has been eliminated, lightly sand the same areas with a piece of fine grit paper. Remove debris that was left behind by the sandpaper by rubbing a tack cloth over them. The cloth has a sticky surface that will pick up small particles.

Apply Rust Inhibiting Spray

Lay a vinyl tarp in front of the door. Apply a rust inhibiting spray to the surface of the door. To do this, stand back from the door several inches and apply the product evenly as you move it over the door's surface in straight lines. The spray will dry clear after a couple hours. A new coat of spray will need to be reapplied each year to keep the metal protected. If any spray gets onto the ground or windows on the door, remove it with a lint free cloth the has been dipped in mineral spirits. Wipe each surface off with a damp cloth when finished.

Keep your garage door maintained and prevent additional damage in the future by spraying it off with a water hose whenever it becomes dirty. Surface stains can be removed with metal cleaner, soapy water, and a sponge.

Finding the Right Garage Door

When my husband and I first built our home, we had no idea which kind of garage door would blend in with the exterior facade of our place. However, after we mulled over a bunch of different options, we decided to go with a few fancy, carriage door styled garage doors. In addition to adding an old-world feel to our place, they also worked incredibly well. I know that it sounds silly, but our garage doors are one of my favorite things about our new place. I want you to love your garage doors as much as I love mine, which is why I built this website.
