1) Choose the Right Equipment

Investing in the right pressure washer for your needs is crucial to achieving optimal results. When selecting a pressure washer, consider:

• Pressure level (PSI): Pounds per square inch
• Flow rate (GPM): Gallons per minute

For most home cleaning tasks, a medium-duty electric pressure washer with a PSI of 1500–2000 and a GPM of 1.5–2.0 should be enough.

2) Use the Correct Nozzle

Pressure washers come with a variety of nozzles, and each one is designed for different cleaning tasks. Choosing the right spray angle helps you clean faster and avoid surface damage.

• 25-degree nozzle: A great starting point for general cleaning (good balance of pressure and coverage)
• 15-degree or 0-degree nozzle: Use carefully for stubborn stains (more concentrated spray)
• 40-degree nozzle: Better for more delicate surfaces (wider, gentler spray)

If you’re unsure, start wider and less aggressive—then adjust as needed.

3) Test Before You Wash

Before starting a full-scale pressure washing project, test your washer on a small, inconspicuous area. This helps you confirm:

• The nozzle and pressure level are effective
• The surface can handle the pressure without damage
• You won’t leave marks, streaking, or etching

This is especially important for delicate surfaces like wood or painted siding, which can be damaged by high pressure.

4) Use the Right Cleaning Solutions

Water alone isn’t always enough—especially for stubborn stains, algae, mold, or mildew. A specialized cleaning solution formulated for pressure washers can boost cleaning power and improve efficiency.

Always follow the manufacturer’s instructions, including dilution ratios, and rinse thoroughly when finished.

5) Work from the Top Down

When pressure washing vertical surfaces like siding or fences, start at the top and work your way down. This helps prevent streaking and ensures more even results.

Gravity works in your favor—dirt and debris flow downward as you clean, so you’re less likely to re-soil areas you’ve already washed.

6) Mind Your Distance

Keeping the right distance between the nozzle and the surface is one of the most important safety factors. Too close can cause damage; too far can reduce cleaning effectiveness.

As a general rule, keep the nozzle at least 12–18 inches away from the surface, then adjust until you find the best balance between cleaning power and surface safety.

Final Reminder

Great pressure washing results come from using the right equipment, nozzle, technique, and distance—not from blasting everything at maximum pressure. When in doubt, test first and use a gentler approach to protect your home’s exterior.
