Safe Pressure Washing Around Your Home

Pressure washing is an excellent way to maintain your home’s exterior, but every surface requires a different cleaning approach. Using the wrong pressure or nozzle can damage paint, wood, glass, and other materials. Here’s how to safely clean common areas around your home.

1. Windows

Windows require extra care.

Tips:

• Use a 40° nozzle.
• Keep the nozzle at least 2 feet away.
• Avoid spraying directly at window seals.
• Never use high pressure on old or damaged glass.

2. Cars

When washing vehicles:

• Use 1200–1900 PSI.
• Select a 40° nozzle.
• Maintain a distance of 12–18 inches.
• Use automotive shampoo instead of household detergents.

3. Roof

Roof cleaning requires caution.

Avoid:

• Walking on wet roofs.
• Using excessive pressure on shingles.
• Spraying upward beneath roofing materials.

Use a low-pressure cleaning method or consult a professional for delicate roofing materials.

4. Wood Deck

Wood can splinter if cleaned incorrectly.

Best practices:

• Use 1500–2000 PSI.
• Spray with the wood grain.
• Keep the nozzle moving continuously.
• Test a small hidden area first.

5. Vinyl Siding

Vinyl siding is easy to clean but should be washed carefully.

Recommendations:

• Use a 25° or 40° nozzle.
• Spray downward, not upward.
• Avoid forcing water behind the siding.

6. Concrete

Concrete can handle higher pressure than most surfaces.

Use:

• 2500–3000 PSI
• 15° or 25° nozzle
• Surface cleaner attachment for large areas

Work in overlapping passes for even cleaning.
