Understanding Garage Door Materials

Garage doors consist of various materials—steel, aluminum, wood, and composite—with different care requirements. For example, steel doors may rust if exposed to abrasive cleaners, while wooden doors are prone to warping when saturated with water. Knowing your garage door’s material is the first step in cleaning it properly.

If you’re unsure what the door is made of, check the manufacturer’s label, which is usually located along the side or top panel. You can also identify the material by look and feel: wood is textured and heavy, while steel or aluminum feels cold and has a smooth, painted surface. Incorrect care can lead to surface damage or buildup in the tracks, which are two common reasons why a garage door gets stuck halfway.

Common Garage Door Cleaning Mistakes

Even with the best intentions, improper cleaning can damage a garage door’s surface or components. Here are four common mistakes to avoid.

1. Using Harsh Chemicals

Bleach, ammonia, and other strong cleaners eat away at protective coatings, causing discoloration and corrosion. Use a soft sponge or cloth with tepid water and a mild detergent instead. Start from the top and work your way down, moving the sponge or cloth in gentle circular motions. For stubborn grime, choose a cleaner that is appropriate for the door type.

2. Ignoring Safety Precautions

Garage doors contain powerful springs and electrical components. Washing the door without cutting power could lead to injury or damage. Unplug the garage door opener or flip the circuit breaker before you begin cleaning. Wear gloves and safety glasses, and avoid spraying water near the opener or control box.

3. Applying Too Much Water Pressure

Power washers can strip paint, dent metal, or force water into seams and joints, especially with wood doors. Stick to a standard garden hose with a gentle spray nozzle. Rinse the door thoroughly but gently, and avoid focusing the stream on vulnerable edges or seams. Soap residue can dull the surface of the door and attract dirt, so remove it all.

4. Neglecting Weatherstripping

That rubber seal at the bottom of a garage door protects the interior from water, pests, and drafts. Abrasive brushes can damage or loosen the weatherstripping. To prevent this, wipe the weatherstripping clean with a damp cloth. Inspect it for cracking or brittleness, and replace it if necessary to maintain the seal.
