Considerations for Effective Pressure Washing
Electric pressure washers from 1,300-2,300 PSI can clean a driveway, but take longer. For large surfaces with heavy stains, more power speeds up the job.
Recommended PSI for Different Surfaces
- Concrete: Recommended PSI ranges from 3,000 to 4,000.
- Wood Deck: Cincinnati exterior cleaning companies suggest 3,000 PSI for residential use.
- Surface Cleaner: Power washer outputting 2,000-4,000 PSI is recommended.
Optimal PSI for Specific Cleaning Tasks
- Removing Paint from Concrete: Optimal PSI between 2,000 and 4,000. Best results with at least 3,000 PSI and 4 GPM flow rate.
Pressure Washer Types
- Electric Models: Offer 1,300-1,700 PSI, lower upfront costs, and maintenance needs.
- Gas Models: Output 2,000-2,800 PSI, suitable for heavy-duty cleaning.
Concrete Pressure Washing Tips
- Pre-treat oil and grease stains before washing.
- Use proper safety gear.
- Wet concrete before applying cleaners to avoid staining.
- Start low with pressure and increase as needed.
Power Washer Usage Recommendations
- Electric washers from 1,300-1,700 PSI for most tasks.
- Gas washers with over 2,000 PSI for tougher applications.
- Power washing uses heated water compared to cold water pressure washing.
