How to clean a Colorbond Pergola – Essential DIY Tips

If you own a Colorbond pergola, you already know that it’s a beautiful addition to any backyard. But over time, even the most durable materials can start to look tired and dirty. Maintaining the appearance of your pergola is important not only for aesthetic purposes but also to prevent damage and extend its lifespan.

In this article, we’ll show you how to clean your Colorbond pergola so that it looks as good as new. With our essential DIY maintenance tips, you can keep your pergola looking great and standing tall for years to come!

Why Do Colorbond Pergolas Need To Be Cleaned?

Colorbond steel is a durable material commonly used in outdoor structures, but its surface can be vulnerable to dirt, grime, and stains that accumulate over time. Cleaning a Colorbond pergola not only enhances its appearance but also helps prevent damage to the surface, such as corrosion or rust, which can compromise its structural integrity.

Here are the most common reasons to clean that you’ll encounter:

  • Mould
  • Algae
  • Lichen
  • Rust
  • Salt spray
  • Dirt

Methods of Cleaning Colorbond Pergolas

Power or Pressure Washing: Power or pressure washing can be an effective method for cleaning your pergola, as it can remove stubborn dirt and grime from the surface. However, if not used correctly, high pressure can damage the Colorbond steel.

An alternative option is to use a garden hose with a low-pressure nozzle, which is gentler on a large surface area while still providing enough force to remove the dirt and debris.

Hand washing: Hand washing with a soft-bristled brush and a mild detergent solution is a safe and effective method for cleaning a Colorbond pergola. It allows you to focus on problem areas and apply the right amount of pressure to avoid damaging the surface.

Hand washing is also a good option if your pergola has delicate or intricate features that may be difficult to clean with a pressure washer or hose.

Popular Cleaning Products Used to Clean Colorbond Pergolas

Vinegar Solution: A vinegar solution is a popular and cost-effective cleaning product. Mixing equal parts of white vinegar and water creates a gentle cleaning solution that can help remove dirt and grime without damaging the Colorbond steel. It’s a natural and eco-friendly option that can also help prevent mould and mildew growth.

Baking Soda: Baking soda is another versatile and inexpensive option. It can be mixed with water to create a paste that’s effective at removing tough stains, or sprinkled directly on the surface and scrubbed with a soft-bristled brush. Baking soda is gentle on the Colorbond steel and can also help neutralise any odours.

Soap and Water: Mild dish soap mixed with warm water can help remove dirt and grime without damaging the Colorbond steel surface. It’s important to rinse the surface thoroughly with water after cleaning to prevent soap residue buildup.

Chemical Cleaning Products: Chemical cleaning products, such as specialised metal cleaners or rust removers, can be effective at removing tough stains and restoring the Colorbond steel’s original shine.

Commercial Solvents: Commercial solvents are powerful cleaning products that can be effective at removing stubborn stains and marks. It’s important to follow the manufacturer’s instructions and safety precautions when using commercial solvents.

The Best Way to Clean Your Colorbond Pergola Roof

The best way to clean your Colorbond pergola roof is to use a pressure washer or garden hose with a low-pressure nozzle attachment, combined with a mild detergent solution. This method is so effective because it allows for thorough cleaning of the surface while minimising the risk of damage.

The pressure washer can easily remove dirt, grime, and stains from the surface, while the mild detergent solution helps break down stubborn marks and provides extra cleaning power.

It’s also relatively quick and easy, allowing you to clean your Colorbond pergola roof in a fraction of the time it would take to clean it by hand. However, it’s important to use the pressure washer carefully to avoid applying too much pressure, which can cause dents, scratches, or other damage.

Step-by-Step Guide to Cleaning Your Colorbond Pergola

We’ll be sharing two different guides, one using a pressure washer and one using a garden hose.

Using a pressure washer:

  1. Begin by sweeping the roof with a broom to remove loose debris, such as leaves, twigs, and dirt.
  2. Mix a mild detergent solution in a bucket of water, following the instructions on the detergent label. Avoid any harsh chemicals or cleaners, which can damage the Colorbond steel.
  3. Fill the pressure washer with the detergent solution, following the manufacturer’s instructions. Use a low-pressure nozzle attachment to reduce the risk of damage to the steel.
  4. Starting at the top of the roof, use the pressure washer to rinse the surface with the detergent solution. Work in sections to avoid missing any spots.
  5. Allow the detergent solution to sit on the surface for a few minutes to break down any stubborn stains or marks.
  6. Switch to a high-pressure nozzle attachment and use the pressure washer to rinse the surface thoroughly. Start at the top of the roof and work your way down, using a sweeping motion.
  7. If there are any stubborn stains or marks remaining, use a soft-bristled brush to gently scrub the surface. Be careful not to apply too much pressure, which can cause damage.
  8. Rinse the roof thoroughly with a garden hose, starting at the top and working your way down. This will ensure that all detergent solution is removed from the surface.

  4. Rinse the surface with a garden hose, starting at the top of the pergola and working your way down.
