The Simple Way You Can Prevent Your Garage Door From Rusting

Rain and snow can pose various challenges in the home like clogs, leaks, and frozen pipes, to more severe problems that stem from water damage. Moisture can also cause issues based on the material it comes in contact with. When water and oxygen meet metal, for example, rust often occurs, which leads to deterioration — keep your metal garage door strong and in good condition by regularly applying metal or car wax to the surface.

When applied to an exterior metal door, wax creates a protective barrier that can help in various ways. Rust is mainly caused by exposure to corrosive substances like water and salt, so the protective barrier that wax forms on the surface prevents corrosives from directly touching the metal. The layer that wax creates on the surface of the metal also helps maintain the door because it makes it difficult for dirt and stains, to stay bonded to the paintwork.

To get the right wax to maintain your garage door and extend its life, you need the right form and product. Choose liquid waxes over pastes and solid waxes because they work better and are very easy to use. Some products to consider are Adam's Spray Wax and Car Guys Hybrid Wax. You should also choose the wax product that is safe for the type of metal surface you have.

Not all waxes are good on a metal door with an aluminum finish, for example. In this YouTube video, car detailing expert Pan The Organizer recommends Graphene Flex Wax by Turtle Wax for aluminum garage doors. Adam's Spray Wax is safe for all surfaces, according to Adam's Polishes, while the Car Guys Hybrid Wax offers the same guarantee and more. In addition to being good for all materials, it works as a polish and sealant and includes UV protection, per Amazon, which means it can protect your metal door from the damaging effects of strong sunlight.

To apply wax to the garage door, you'll need clean, soft cloths and applicator pads, mild detergent, water, and your chosen liquid wax product. Start by cleaning the door. Brush off any dirt, dust, or grime from the surface and then go over it again using the detergent, water, and soft cloth to wipe off, working in sections. Note that any existing rust should also be removed before the wax is applied. Use another cloth to wipe away any moisture and leave it to dry completely. Next, apply the wax by following the product instructions.

You typically need to apply a small amount of wax to an applicator pad and rub it on the surface, covering the door evenly. Pan The Organizer shakes the bottle well, sprays a bit of it on a microfiber towel, and then wipes it on the surface thoroughly (via YouTube). Let the wax dry according to the suggested time and use a cloth to buff the surface. This will remove any excess wax and enhance the shine of your metal garage door. Aim to clean and wax it twice a year, or more if you're in a coastal area due to the high salt content in the air. The hinges, tracks, and other moving parts of your garage door are also susceptible to rusting, so don't forget to apply a lubricant to them as well.
