Do you want to make the outside of your house look brand new? Pressure washing aluminum siding can help breathe life back into older and dingy homes. When done correctly, it can also increase durability, preventing further wear from the elements or exposure to dirt and debris.

How to Pressure Wash Aluminum Siding

Aluminum siding is popular with many homeowners due to its durability and low maintenance. However, over time, aluminum siding can accumulate dirt and grime from the environment. This accumulation can make your home’s exterior look dull and unappealing.

If you’re looking for an easy and cost-effective way to revitalize your home’s exterior, pressure-washing aluminum siding is one of the best options available! Here, we’ll explain everything you need to know about how to pressure wash aluminum siding.

What Will You Need?

Before you get started, make sure you have the following items on hand to ensure a smooth and efficient pressure washing experience:

  • A pressure washer with at least 2,000 PSI (pounds per square inch) and a flow rate of 1.4 gallons per minute
  • A garden hose with sufficient length
  • An extension wand for hard-to-reach areas
  • A safe and effective cleaning solution that is specifically designed for pressure washing aluminum siding
  • Safety gear, including goggles and closed-toe shoes

Once you have all of the necessary equipment, it’s time to start pressure washing!

10 Easy Steps on How to Pressure Wash Aluminum Siding

Step 1. Safety First

Start by wearing your safety gear; goggles and closed-toe shoes are essential. Make sure the area is clear of any obstacles that may cause slips or falls. You can also cover nearby plants with plastic sheets or tarps to protect them from any cleaning solution overspray.

Step 2. Prepare the Pressure Washer

Begin by connecting your garden hose to the water inlet of the pressure washer. Attach the extension wand to the pressure washer’s gun. Next, fill the detergent dispenser with an appropriate cleaning solution. Ensure everything is secured tightly to avoid leaks. Remember to set the pressure washer in a low-pressure setting (around 2000 PSI) to prevent damaging the siding.

Step 3. Test the Pressure Washer

Before directing the pressure washer onto your aluminum siding, testing it on an inconspicuous area is crucial. This step ensures the pressure level and cleaning solution won’t harm the siding. If you notice any discoloration or damage, adjust the pressure level or change your cleaning solution accordingly. Once you know the settings, you can wash the larger areas.

Step 4. Apply the Cleaning Solution

Starting from the bottom and working your way up, spray the cleaning solution onto the siding using the low-pressure setting. This method prevents the solution from dripping down onto the already clean areas.

Allow the solution to sit for 5-10 minutes, but ensure it doesn’t dry out. You may need to reapply the solution if it starts to dry. This step allows the cleaning solution to penetrate and loosen the dirt and grime on the siding.

Step 5. Rinse the Siding

After the cleaning solution has had enough time to work, it’s time to rinse the siding. Switch the pressure washer to a high-pressure setting (still being mindful not to set it too high). Remove the detergent dispenser if necessary.

Start rinsing from the top of the siding and work your way down, ensuring you thoroughly rinse off all the cleaning solutions. The force of the water should carry the dirt and grime down with it, leaving your aluminum siding looking fresh and clean.

Step 6. Use a Soft Brush for Stubborn Stains

Sometimes, you may encounter stubborn stains that can’t be removed with pressure washing. Use a soft-bristle brush to gently scrub these tricky spots away gently along with the cleaning solution. It’s essential to use a soft brush designed explicitly for siding to avoid causing any scratches or damage.

Step 7. Inspect and Repeat if Necessary

After you have rinsed off the siding, take a moment to inspect your work. Look for any areas that may still have dirt or grime. If you find anything, you may need to repeat the process from Step 4. Apply the cleaning solution again, let it sit, and then rinse it off. Make sure not to rush the process; patient and thorough work will yield the best results.

Step 8. Allow the Siding to Dry

Once you’re satisfied with the cleanliness of your siding, allow it to air dry. Do not use any form of forced drying as it may cause streaking or water spots. During this time, remove any protective coverings from your plants and ensure all your equipment is clean and stored away properly.

Step 9. Perform a Final Inspection

After the siding is completely dry, perform a final inspection. Walk around your house and check for areas that may have been missed or still have visible stains. Repeat steps 4 through 8 if necessary until you’re satisfied with the result. Your aluminum siding will look as good as new with persistence and patience!

Step 10. Regular Maintenance

Establish a regular maintenance schedule to keep your aluminum siding looking its best. Pressure washing your siding once or twice a year can help keep dirt and grime from building up. Regular maintenance can extend the lifespan of your siding and keep your home looking beautiful.

By following these ten easy steps on how to pressure wash aluminum siding, you can easily and effectively remove years of dirt and grime buildup from your home’s exterior.

5 Additional Tips and Tricks

  1. Use the Right Pressure: Aluminum siding is durable, but too much pressure can cause damage. Use a pressure washer with adjustable settings and start on the lowest setting before gradually increasing the pressure as needed.
  2. Pre-Soak the Siding: For tough stains or build-up, pre-soaking can help loosen and remove dirt more easily. Mix water and mild detergent in a bucket, then apply it to the siding using a soft bristle brush or a low-pressure nozzle on your pressure washer.
  3. Avoid Direct Contact: When using a pressure washer, it’s essential to keep the nozzle at least 12 inches away from the siding. Direct contact with the surface can cause dents or scratches, which will be costly.
  4. Work in Sections: Instead of cleaning the entire house at once, work in sections. This will help you maintain control and avoid missing any spots. Plus, it’s less physically demanding to pressure wash in smaller areas.
  5. Try Spot Cleaning: If only a few small areas of your aluminum siding need cleaning, you may not need to pressure wash the entire house. Instead, try spot cleaning using a soft bristle brush and a mild detergent solution.

With these additional tips and tricks, you can confidently pressure wash your aluminum siding without causing any damage.

5 Things You Should Avoid

  1. Avoid High Pressure: Using a high pressure setting makes it easy to damage your aluminum siding. It’s best to start at a low pressure setting and slowly increase it, if necessary.
  2. Don’t Use Abrasive Cleaners: Abrasive cleaners can scratch and damage your aluminum siding. Always choose a mild, non-abrasive cleaner to protect the finish of your siding.
  3. Avoid Spraying Windows or Doors Directly: High pressure on windows or doors can result in leaks or damage. Always angle your spray away from these areas.
  4. Remember Safety Precautions: Always wear safety goggles and gloves when operating a pressure washer. This can prevent potential injuries.
  5. Don’t Rush the Job: Take time while washing your aluminum siding pressure. Rushing may result in missed spots or damage to your siding. Patience and thoroughness are key to a successful job.

By avoiding these common mistakes, you can ensure a successful and safe pressure washing experience for your aluminum siding.
