Understanding Pressure Washer Specs
PSI (Pounds Per Square Inch)
What it is: The pressure or "strength" of the spray
What it does: Determines what you can clean
Home use ranges:
- 1,500-2,000 PSI: Light-duty cleaning (patio furniture, vehicles)
- 2,000-2,800 PSI: Medium-duty (driveways, decks, siding)
- 2,800-3,200+ PSI: Heavy-duty (stubborn stains, large areas)
GPM (Gallons Per Minute)
What it is: Water flow rate
What it does: Determines how fast you clean (more water = faster cleaning)
Home use ranges:
- 1.2-1.5 GPM: Light-duty electric models
- 1.5-2.3 GPM: Medium-duty home use
- 2.3+ GPM: Heavy-duty and professional use
Cleaning Units (CU)
The complete picture: PSI × GPM = Cleaning Units
Example: 2,000 PSI × 1.8 GPM = 3,600 CU
This single number tells you the overall cleaning power better than PSI alone.

Pressure Washer Safety
Critical Safety Rules
1. Never aim at people, pets, or yourself - High pressure can cause serious injury
2. Use lowest effective pressure - Start with wide spray pattern
3. Wear eye protection - Debris flies unexpectedly
4. Wear closed-toe shoes - Protect your feet
5. Be careful on ladders - Kickback can be dangerous
6. Don't use with extension cord indoors - Outdoor use only
7. Watch electrical connections - Keep dry, use GFCI
Surface-Specific Tips
Wood (decks, fences):
- Start with wide spray (white/green nozzle)
- Keep nozzle moving to prevent damage
- Test inconspicuous area first
- Don't get too close (stay 12+ inches away)
Concrete (driveways, patios):
- Can use narrower spray pattern
- Work in sections
- Use detergent for stubborn stains
- Consider surface cleaner attachment
Vehicles:
- Use wide spray pattern (40° or soap nozzle)
- Stand further away (18+ inches)
- Never use 0° red nozzle
- Rinse thoroughly after washing
Siding:
- Use white/green nozzle
- Work downward (don't spray upward under siding)
- Keep nozzle at least 12 inches away
- Watch for loose siding that could blow off
Common Spring Cleaning Projects
Driveway Cleaning
Equipment: 2,300+ PSI, surface cleaner attachment recommended
Technique:
1. Clear debris from surface
2. Apply detergent (for tough stains)
3. Let detergent sit 5-10 minutes
4. Pressure wash in sections
5. Work in overlapping strokes
6. Rinse thoroughly
Pro tip: Use a surface cleaner attachment for even, streak-free results
Deck Cleaning and Prep
Equipment: 2,000-2,500 PSI, green/white nozzle
Technique:
1. Clear deck of furniture and debris
2. Sweep away loose material
3. Test pressure on inconspicuous area
4. Work with grain of wood
5. Keep nozzle moving to prevent gouging
6. Allow to dry completely before staining
Pro tip: Hold nozzle at a 45° angle for best results
House Siding
Equipment: 2,000-2,300 PSI, white/green nozzle
Technique:
1. Close windows and cover outlets
2. Remove loose debris (cobwebs, leaves)
3. Work from bottom up (when applying detergent)
4. Rinse from top down
5. Keep nozzle at consistent distance
6. Don't spray directly at windows/doors
Pro tip: Be extremely careful around windows and siding seams - water can penetrate behind siding

Technique:
1. Remove cushions (clean separately)
2. Test pressure on small area first
3. Keep nozzle 18+ inches away

- Unloader valve issue
- Worn pump seals (may need service)
Engine Won't Start (Gas Models)
- Check fuel level
- Verify spark plug connection

Environmental Considerations
Water Usage
Pressure washers use less water than you'd think:
- GPM × minutes used = total gallons
- Example: 2.0 GPM × 30 minutes = 60 gallons
- Compare to: Garden hose uses ~10-15 GPM
Pressure washing typically uses 50-75% less water than garden hose cleaning.
Detergent Disposal
- Collect runoff when possible
- Avoid storm drains when using chemicals
- Use biodegradable detergents
- Check local regulations
Noise
Electric: 70-80 dB (quieter)
Gas: 85-95+ dB (louder)
Consider neighbors and local noise ordinances.

Frequently Asked Questions
Q: How often should I pressure wash my house?
A: Most homes benefit from annual cleaning. Spring is ideal as it removes winter buildup. Areas with high humidity or pollen may need twice-yearly cleaning.
Q: Can I damage my house with too much pressure?
A: Absolutely! Always start with the lowest effective pressure and widest spray pattern. Test on an inconspicuous area first. Never use the red 0° nozzle on house surfaces.
Q: Should I use detergent or just water?
A: For general cleaning, water is sufficient. Use detergent for stubborn stains, mold/mildew, or heavily soiled areas. Always follow with a thorough rinse.
Q: Is electric or gas better for home use?
A: For most homeowners, electric is perfect: quieter, easier to maintain, and adequate power. Choose gas only for large properties or heavy-duty cleaning needs.
Q: Can I use bleach in my pressure washer?
A: Only with detergents specifically designed for pressure washers. Regular bleach can damage seals and pumps. Use approved cleaners instead.
Q: How close should I hold the nozzle to the surface?
A: Start 18-24 inches away and gradually move closer if needed. Keep the nozzle moving to prevent damage. Different surfaces require different distances.
Q: What PSI do I need for a driveway?
A: 2,300+ PSI for concrete driveways. Lower PSI works but takes longer. Use a surface cleaner attachment for best results.
Q: Can I wash my car with a pressure washer?
A: Yes, but use the white 40° nozzle or soap nozzle, stand 18+ inches away, and never use the red 0° nozzle - it can strip paint and damage trim.
Spring cleaning doesn't have to be a dreaded chore. With the right pressure washer, you can transform your home's exterior in a single weekend, leaving more time to enjoy the beautiful spring weather!
