A Step-by-Step Guide to Cleaning Metal Fences, including Colorbond

Metal fences, like Colorbond fences, offer durability and aesthetic appeal to any property. However, over time, they can accumulate dirt, grime, and even rust, which can diminish their appearance. Regular maintenance and cleaning are essential to preserve the pristine look of your metal fence. In this blog post, we’ll provide you with a comprehensive step-by-step guide on how to clean your metal fence effectively, with a specific focus on Colorbond fences.

Step 1: Gather the Necessary Tools and Materials

Before you begin cleaning, ensure you have the following items at hand:

  • Garden hose or pressure washer
  • Soft-bristle brush or sponge
  • Mild detergent or metal fence cleaner
  • Bucket
  • Gloves
  • Safety goggles (if using a pressure washer)
  • Towels or rags for drying

Step 2: Prepare the Area

Clear any debris or vegetation around the fence to ensure unobstructed access. Move any furniture or objects that may be in close proximity to the fence.

Step 3: Rinse the Fence

Start by thoroughly rinsing the fence with a garden hose or pressure washer. If using a pressure washer, make the pressure does not exceed 2500 PSI to avoid damaging the fence. This initial rinse helps remove loose dirt and debris, making the cleaning process easier.

Step 4: Prepare the Cleaning Solution

Fill a bucket with water and add a mild detergent or a specialised metal fence cleaner. Follow the manufacturer’s instructions for the appropriate dilution ratio.

Step 5: Scrub the Fence

Dip a soft-bristle brush or sponge into the cleaning solution and gently scrub the metal fence. Begin at the top and work your way down, ensuring all surfaces are covered. Pay extra attention to areas with stubborn stains or spots.

Step 6: Spot Cleaning for Stubborn Stains

For particularly stubborn stains or rust spots, you may need to use a more targeted approach. Create a paste by mixing baking soda with water until it forms a thick consistency. Apply the paste to the stained areas and let it sit for a few minutes before scrubbing with a brush. Rinse thoroughly afterwards.

Step 7: Rinse Again

After scrubbing, thoroughly rinse the fence with a garden hose or pressure washer to remove the cleaning solution and any loosened dirt.

Step 8: Dry the Fence

Using towels or rags, dry the metal fence to prevent water spots and minimize the risk of rust formation. Pay attention to hard-to-reach areas and joints where moisture can accumulate.

Step 9: Inspect and Touch-Up

Take a moment to inspect the fence for any chipped paint or signs of rust. If you notice any areas that require touch-ups, consult the fence manufacturer’s guidelines for the appropriate method of repair or repainting.


Cleaning your metal fence, including Colorbond, is a vital part of its maintenance routine. By following these step-by-step instructions, you can effectively remove dirt, grime, and stains, and keep your fence looking pristine for years to come.
