2. Choosing the Right PSI for Effective Cleaning

Choosing the Right PSI for Effective Cleaning

PSI or pounds per square inch is one of the critical factors you must undertake before buying a cordless pressure washer. It signifies the pressure of water. However, it is important to understand that higher PSI does not mean efficient cleaning. You can damage your surface with high pressure.

2.1 How much PSI is needed to safely pressure wash different areas of a house with a cordless pressure washer?

For general home cleaning tasks, cordless pressure washers with a PSI range of 150 to 435 are typically sufficient. However, for more heavy-duty tasks such as cleaning concrete driveways, a higher PSI may be required. While corded pressure washers often offer higher PSI options, some cordless models are also capable of delivering the necessary pressure for such tasks.We have explained the optimal PSI for various surfaces below:
Exterior Siding:
  1. Vinyl Siding: 1300-1600 PSI is a good range. You can effectively remove dirt without destroying the surface.
  2. Wood Siding: The optimal PSI depends on the wood's hardness.
    1. Hardwood Siding: Higher PSI in the range of 1000-1200 PSI for smooth cleaning.
    2. Softwood Siding: Since the wood has a softer surface, a much lower PSI of 500-800 PSI is recommended.
  3. Brick: 1500-2000 PSI is a secure range for cleaning brick.
  4. Stucco: Stucco requires a lower around 1500 PSI to protect the surface from damage.
  5. Aluminum: A lower PSI range of 1250-1450 PSI is good for aluminum surfaces.
Decking:
    1. Treated Pine: Start with a very low PSI of 500. Increase gradually if you face tough dirt and debris
    2. Cedar: Set the pressure to 600-800 PSI. Cedar has a softer surface. More pressure can make it vulnerable.
    3. Composite: While composite materials are generally durable, the appropriate PSI can vary depending on the specific type and thickness. Aim for a PSI range of 1200-1800, but always consult the manufacturer's manual for the recommended pressure setting.
Concrete Driveways and Walkways:
  1. General Cleaning: A range of 2000-3000 PSI is good for smooth cleaning.
  2. Stain Removal: Tough stains like oil or grease require closer to 3000 PSI.
Roofing:
    1. Tile: Use a gentle pressure of around 1200 PSI.
    2. Asphalt Shingles: Keep the pressure below 1000 PSI and use a soft wash method to minimize shingle damage.
Outdoor Furniture:
  1. Plastic: A low pressure of 600-800 PSI is sufficient to remove dirt without damaging plastic furniture.
  2. Wood: 
    1. Softwoods (Pine): Use 600-800 PSI to avoid damaging the softer wood fibers.
    2. Hardwoods: You can use a slightly higher pressure, up to 1200 PSI.
  3. Metal: For removing rust and flaking paint, a range of 1500-2000 PSI is suitable.
Fencing:
    1. Wood Fences: The ideal PSI depends on the wood's condition. A lower range of 500-800 PSI is optimal for weathered wood.
