What Surfaces Can You Pressure Wash? A Complete Guide

Pressure washing, or power washing, is one of the most effective ways to clean a variety of surfaces around your home or business. Whether you're looking to refresh the exterior of your house, clean a driveway, or even restore a wooden deck, pressure washing can deliver impressive results. However, it's important to know which surfaces are safe to clean with a pressure washer and which ones could be damaged by the forceful water stream. In this complete guide, we’ll walk you through the different surfaces that can benefit from pressure washing, as well as offer expert tips to ensure the job is done correctly and safely.

What is Pressure Washing?

Before diving into the surfaces you can pressure wash, let’s quickly go over what pressure washing is and how it works. Pressure washing uses a high-pressure stream of water to remove dirt, grime, mold, mildew, and other debris from surfaces. The water is typically heated to provide more cleaning power, especially for stubborn stains. A pressure washer can vary in pressure levels, ranging from light-duty machines perfect for washing cars to heavy-duty commercial units used for cleaning large buildings or driveways.

Surfaces That Can Be Pressure Washed

Now that we have a basic understanding of pressure washing, let’s explore the different surfaces that you can clean using this method. It’s important to remember that each surface may require different pressure settings to avoid any potential damage. Let’s break it down by category.

1. Driveways and Sidewalks

Driveways and sidewalks are some of the most common surfaces to be pressure washed. These outdoor areas often accumulate dirt, oil stains, algae, moss, and tire marks over time. A high-pressure wash is perfect for these surfaces, as it can easily lift and remove the debris, restoring their appearance.

Materials: Concrete, Asphalt, Pavers
Tips: When pressure washing driveways, it’s best to use a low to medium pressure setting (2,000 to 3,000 psi) to avoid damaging the surface. For stubborn stains like oil, consider using a degreaser before washing.

2. House Exteriors (Siding, Brick, Stucco, and Vinyl)

Your home’s exterior can benefit from regular pressure washing to keep it looking fresh and clean. Different materials require different pressure levels and techniques, so it’s essential to be cautious.

Materials: Vinyl Siding, Wood Siding, Brick, Stucco, Aluminum, and Fiber Cement Siding
Tips: For softer materials like vinyl and wood, it’s important to use a lower pressure setting (around 1,500 to 2,000 psi). Brick and stucco can withstand higher pressures but be careful with any loose mortar. For delicate surfaces like stucco, always use a fan nozzle to distribute the pressure evenly.

3. Decks and Patios

Wooden decks and patios can collect dirt, mold, and mildew, making them look weathered and dull. Pressure washing can revive the appearance of a deck, but it’s crucial to adjust the pressure to avoid damaging the wood.

Materials: Wood, Composite, Concrete, Brick
Tips: For wood decks, it’s best to use a low-pressure setting to avoid gouging or splintering the wood. A pressure range of 1,200 to 1,500 psi is ideal for wooden surfaces. Composite decking can handle slightly higher pressure but should still be washed with care. After pressure washing, consider sealing the deck to protect it from future damage.

4. Fences (Wood, Vinyl, and Metal)

Fences are constantly exposed to the elements, causing them to gather dirt, mold, algae, and grime. Pressure washing is a great way to restore a fence’s appearance and extend its lifespan.

Materials: Wood, Vinyl, Metal, Chain-Link
Tips: Wooden fences can be sensitive to high-pressure water, so it’s important to use a low pressure setting (around 1,500 psi). For vinyl or metal fences, you can increase the pressure slightly (2,000 psi) to remove dirt and rust stains effectively. Always ensure the nozzle is at least 12 inches away from the surface to prevent damage.

5. Roofs (Asphalt Shingles, Tile, and Metal)

Roofs can gather debris, moss, algae, and lichen, which can damage the shingles and tiles over time. Pressure washing your roof can help extend its lifespan and improve curb appeal.

Materials: Asphalt Shingles, Tile, Metal, Slate
Tips: It’s crucial to use the right pressure when washing a roof to avoid damaging the shingles or tiles. Typically, a low pressure setting (1,200 to 1,500 psi) should be used. Never pressure wash a roof at high angles or forcefully, as this can cause damage to the roof’s structure. Always hire a professional if you're unsure.

6. Gutters

Cleaning gutters is a necessary task that helps maintain your home’s overall health. Pressure washing gutters can remove dirt, leaves, moss, and debris that have built up over time.

Materials: Aluminum, Vinyl, Steel
Tips: While gutters can withstand high-pressure water, it’s recommended to use a lower pressure setting to avoid damaging the fascia board or causing water to get into areas it shouldn’t. A range of 1,500 to 2,000 psi is ideal.

7. Cars and Boats

Pressure washing is a great way to clean vehicles, boats, RVs, and other large vehicles. However, be careful when cleaning these surfaces, as the pressure can easily damage the paint or cause water to enter sensitive areas like the engine or electrical components.

Materials: Car Paint, Fiberglass, Metal, Boat Hulls
Tips: When pressure washing a car, it’s important to use a very low pressure setting (around 1,200 psi) and a fan nozzle to avoid damaging the paint. Never aim the water directly at the engine or exhaust areas. For boats, you may need to use a specialized attachment to safely clean the hull without damaging the finish.

8. Outdoor Furniture

Outdoor furniture can accumulate dust, bird droppings, and general dirt, making it look worn out and dirty. Pressure washing is a great way to restore the appearance of furniture made from wood, plastic, or metal.

Materials: Wood, Plastic, Metal, Fabric (cushions)
Tips: Use a lower pressure setting for wood and fabric furniture (around 1,500 psi), while higher pressure (2,000 to 2,500 psi) is fine for metal and plastic pieces. Always be cautious when washing fabric cushions, as pressure can cause water to seep inside.

9. Concrete Walkways and Patios

Concrete walkways, patios, and even pool decks often accumulate stains, dirt, and algae. Pressure washing is one of the most efficient ways to keep these surfaces clean.

Materials: Concrete, Pavers, Stones
Tips: Concrete surfaces generally require a higher pressure setting (2,500 to 3,000 psi) to thoroughly clean the surface. Be sure to use a rotating nozzle to prevent streaks and uneven cleaning.

10. Pool Areas

Your pool area, including tiles, decking, and surrounding areas, can collect debris, mold, and mildew. Pressure washing ensures that the area remains safe, clean, and inviting.

Materials: Concrete, Tile, Stone, Brick
Tips: For pool areas, avoid using high pressure on tiles or stones, as they may crack or become loose. A moderate pressure setting of 2,000 psi is usually enough for concrete or stone pool decks.

Tips for Pressure Washing

Know Your Pressure Washer: Always check your pressure washer’s maximum pressure rating and adjust accordingly based on the surface you’re cleaning.
Use the Right Nozzle: Pressure washers come with different nozzles that control the water’s spray pattern. For example, a 0-degree nozzle provides a direct stream of water, while a 40-degree nozzle gives a wide fan spray. Select the right nozzle based on the material you're cleaning.
Start from a Distance: Always begin pressure washing from a distance, especially on more delicate surfaces, and gradually move closer as needed.
Use Detergents: For tougher stains like mold or mildew, consider using a cleaning solution designed for pressure washing. Always check the manufacturer’s recommendations to ensure compatibility with your equipment.
