Cleaning Your Garage — Here’s How!

A well-maintained garage door is not only a visual calling card for your home, but also reliably protects the interior of your garage. But what should you do if the surface suddenly looks dull, dirt has become ingrained, or the shine has completely disappeared?

In this article, we’ll show you why garage doors require special care, what mistakes you should avoid when cleaning them, and which products really help to make your door shine again—without damaging the surface.

Why your garage door gets dirty quickly

Garage doors are among the most heavily used components of a house. Every day, they are exposed to external influences such as:

  • Rain and humidity

  • ultraviolet radiation

  • Dirt, dust, and pollen

  • Bird droppings and tree resin

  • Road salt and exhaust residues

exposed. Over time, all these factors cause the surface to discolor, fade, chalk, or even become stained. This is particularly evident on coated or painted metal surfaces, such as those commonly used in modern garage doors.

Common mistakes: Cleaning with the wrong products

In a pinch, many people resort to classic household remedies such as dish soap, glass cleaner, or even vinegar water. But be careful: these solutions are not designed for sensitive exterior metal surfaces and can actually damage them.

Other common mistakes:

  • Scouring cream or aggressive cleaners: These can leave micro-scratches and damage the paintwork.

  • Hard brushes or sponges: Cause visible scratches, especially on glossy coatings.

  • No protection after cleaning: without sealing, new dirt will immediately stick again.

The result? Instead of a clean door, in the worst case scenario you will end up with a permanently dull, stained, or damaged garage door.

Glossy or matte? The surface makes the difference

Before cleaning your garage door, you should know whether it has a glossy or matte metal surface. This is because both types require different care products to ensure that they are not only clean but also protected in the long term.

These look elegant and high-quality, but are sensitive to scratches and discoloration. The shine can quickly be lost, especially if cleaned improperly.

🪶 Matte metal gates

Modern, matte coatings are currently in vogue—but they are also vulnerable: incorrect care can quickly lead to shiny spots, streaks, or “greasy” surfaces.
