Master the Art of Exterior Cleaning: Your Complete Guide to Customized House Washing for Every Siding Material

When it comes to maintaining your home’s curb appeal and protecting your investment, understanding the right house washing techniques for your specific siding material is crucial. Different siding materials require different cleaning techniques, and using the wrong approach can lead to costly damage or voided warranties. Whether you have vinyl, wood, brick, fiber cement, or stucco siding, each material demands a tailored cleaning strategy to ensure both effectiveness and preservation.

Why Siding-Specific Cleaning Matters

One of the most common mistakes when cleaning the siding on a house is cleaning with a power washer set on high. This leads to damage and expensive repairs, and in some cases, according to Yaeir, can even ‘void warranties on some siding materials.’ Understanding your siding type isn’t just about aesthetics—it’s about protecting your home’s structural integrity and maintaining your warranty coverage.

Vinyl Siding: The Low-Maintenance Champion

The most attractive quality of vinyl is that of all siding materials, it requires the least attention. For routine cleaning, vinyl needs ‘only a mild detergent and a garden hose or a soft-bristle brush’. However, caution is still required. Pressure washing can damage your vinyl siding if it is not done correctly, as pressure washers can blast water at up to 3300 PSI, which can remove paint and even tear through the siding or damage the layers behind it if applied to a targeted area.

Best practices for vinyl siding include:

• Clean vinyl siding ‘at least once a year to prevent the accumulation of dirt and grime’
• Cold water is recommended when cleaning vinyl siding
• Use a lower pressure when washing the siding to prevent water from getting behind it
• For routine cleaning, a simple rinse with a garden hose is often enough

Wood Siding: Handle with Care

For homeowners with wood siding, pressure washing can be a double-edged sword. While it offers a method to clean and refresh the siding’s appearance, improper techniques can cause irreparable damage. If you want to clean a wood surface, a soft wash is the best method.

Key considerations for wood siding:

• Use a solution prepared from TSP, bleach, and water. ‘Direct high pressure is to be avoided, though’, he cautions. Use the low setting on your pressure washer instead
• Wood siding doesn’t need to be cleaned all that often. Every three to five years will be enough ‘to preserve its integrity’
• Keep the nozzle moving to prevent water from concentrating on one area, which could soak into and damage the wood. Allow the siding to dry completely, which may take a day or more, depending on weather conditions. This drying period is crucial for preventing trapped moisture, which could lead to wood rot or mold growth

Fiber Cement: The Durable Modern Choice

Fiber cement siding for home exteriors is extremely easy to maintain. Unlike wood or vinyl, fiber cement siding can be kept clean with minimal effort. However, specific precautions are necessary. While using a garden hose to wash your fiber cement siding is acceptable, you should never use a high-pressure power washer to clean your siding. Power washing can damage your siding, and if you mar your siding while cleaning, the repairs won’t be covered by warranty.

Fiber cement cleaning guidelines:

• To clean fiber cement siding with a pressure washer – A pressure washer can help you cover more ground quickly, but applying too much pressure can actually do damage to your fiber cement siding. To reduce the risk of damage, stay at least 6 feet from the wall and keep the pressure below 1,500 psi
• It is recommended to clean fiber cement more frequently than vinyl and wood – once every 6 to 12 months. This will keep the material fresh and clean as well as maintain its durability over the years
• You should never use abrasive chemical products to clean your fiber cement siding. Gentle products, like dish soap, work great and won’t damage your siding

Brick and Stone: Gentle Approaches for Durable Materials

With stone veneer, it’s best to avoid the higher pressure and heat of power washing. It’s also susceptible to damage from bleach and acid-based cleaners, so we advise using soft wash techniques with this siding. For brick surfaces, after pressure washing, it’s critical to allow the brick to dry completely, which may take up to 24-48 hours depending on weather conditions. This drying process is essential to prevent any retained moisture from causing issues within the brick or mortar.

Essential Safety and Best Practices

Regardless of your siding material, certain universal principles apply:

• Work from the Bottom Up: Start at the bottom of the house and work your way up to prevent streaking. Rinse Thoroughly: Rinse the cleaning solution completely before it has a chance to dry on the surface
• Always do a small test area and follow the instructions provided by the manufacturers
• The frequency of cleaning and maintenance required for your type of siding will depend on your home’s geographic location, climate, and atmospheric substances your home is exposed to. For example, if your house is situated close to a freeway or industrial area, you can expect a heavier dose of dirt and grime on your exterior siding and you may need to clean it more frequently
