Rust is not only unsightly, but it can be very hard to get rid of once it has taken hold, and can be especially problematic if it sets in on an access to your home or business on a metal door frame. Here are a few simple methods to keep that metal frame rust-free.
If the door is located in a damp area, such as a basement, or you live in a naturally humid environment, you may want to consider using a rust primer on your metal door frame. You can find these products at any hardware store, where they are generally available in paint or spray form. They will help seal the frame and prevent oxygen from getting into the metal.
When you do your yearly spring cleaning, you may want to apply a thin coat of metal wax to the door frame. This will help to stave off the process of rusting.
Believe it or not, dust can encourage rust. Keep up on cleaning your door frames when you do your normal dusting routine. Simply take a dry cloth and wipe along the frame, and be sure to open the door and get the metal on the inside as well.
If you’ve already noticed some rust on the frame, it doesn't mean you have to immediately start thinking about a replacement. You can try a number of products to remove the existing rust. WD-40 works well to loosen rust, and products with phosphoric acid in it will also do the trick. The acid will actually expose new metal when used. The easiest way to get this effect is to use Coca Cola with a small amount of baking soda, and apply the mixture with a clean towel or rag. Just be sure to remove it all to avoid other problems, like ants!
