how to clean aluminium siding?

Cleaning aluminum siding is an important task to keep it looking new and to extend its lifespan. In this article, we will explore the question “How to clean aluminium siding?

Here are some steps to clean aluminum siding:

1. Rinse: Start by rinsing the siding with a well-directed stream of water from your garden hose. Direct the spray in a downward direction over the siding, working from the top down. This will remove most of the dirt and grime.

2. Hand washing: Use a bucket of warm water with Spic and Span, 409, or any other all-purpose cleaner along with a long-handled soft-bristled brush and begin scrubbing any dirt or grime still remaining.

Scrub with the length of the aluminum siding starting at the top and working downward. Work in three or four-foot sections from top to bottom to prevent the surface from drying out and having to scrub the area again.

3. Rinse again: Rinse the siding thoroughly with clean water after cleaning. Always start at the top of the house and move downward, as this rinses any particles down to the ground.

4. Pressure washing: If there is any mildew or mold present, you will need to use a cleaner that is specifically designed to kill it. Pressure washing is the most common method for how to clean aluminum siding.

The average cost to pressure wash a house from a pro is about $300. If you are using a power washer, hold it at least 12 inches away from the surface of the siding and spray from the bottom up to avoid scratching the surface of the siding.

5. Stain removal: For stubborn stains, try scrubbing with a soft-bristle brush that attaches to the pressure washer. If the siding looks clean after pressure washing, but there are still some stains, try a solution of pickling vinegar and isopropyl alcohol. Just mix them 1:1, then add a couple of drops of dish soap. Have a go with a scrub brush.

It is important to clean aluminum siding at least once a year to keep mold and mildew from appearing. Cleaning aluminum siding before painting is also important to remove any dirt or stains and help the paint adhere better.

What should be done if you notice oxidation on aluminum siding?

If you notice oxidation on your aluminum siding, it means that the paint applied to the surface of the aluminum is starting to break down, resulting in a white chalky substance on the siding. 

Here are some steps to clean aluminum siding with oxidation:

1. Rinse: Start by rinsing the siding with a well-directed stream of water from your garden hose. Direct the spray in a downward direction over the siding, working from the top down. This will remove most of the dirt and grime.

2. Cleaning solution: Mix TSP (Tri-Sodium Phosphate) with warm water in a chemical sprayer and spray it onto the wet aluminum siding. Let the cleanser sit for a couple of minutes before scrubbing with a siding brush.

3. Scrubbing: Use a siding brush with soft bristles that won’t scratch the paint or gouge the aluminum like other hard brushes. Scrub away the debris once the TSP has loosened it up. Rinse the wall from top to bottom with the hose set on an angled flow, directing the water down the siding to prevent moisture from getting trapped underneath.

4. Pressure washing: If the oxidation is severe, you may need to use a pressure washer. However, be careful not to get too close to the siding, as this can damage it. Start with the pressure low and then dial it up as you go and feel more comfortable.

It’s important to note that if the oxidation is too severe, you may need to consider repainting or replacing the affected siding. In this case, it’s best to consult a professional for advice.

However, if the oxidation is severe, it may take several hours or even days to remove it completely. Here are some factors that can affect the time it takes to remove oxidation from aluminum siding:

1. Severity of oxidation: The more severe the oxidation, the longer it will take to remove it. Mild oxidation can be removed with a simple cleaning solution, while severe oxidation may require a more intensive cleaning process.

2. Cleaning method: The method used to clean the oxidation can also affect the time it takes to remove it. For example, pressure washing may be faster than using a cleaning solution and scrub brush.

3. Size of the area: The larger the area that needs to be cleaned, the longer it will take to remove the oxidation.

4. Weather conditions: The weather conditions can also affect the time it takes to remove oxidation from aluminum siding. For example, if it’s raining or humid, it may take longer for the siding to dry after cleaning.
