How to Use This Calculator
  1. Select surface type (concrete, wood, vinyl siding, vehicle, etc.) and enter area in sq ft.
  2. Set soil level (light, moderate, or heavy).
  3. Review Recommended PSI, Water Gallons needed, and estimated cleaning time.
  4. Always test PSI on an inconspicuous area — too high can etch concrete or damage paint.

What each input means

Surface Type
0 = Concrete, 1 = Wood deck, 2 = Vinyl siding, 3 = Brick.
Area
Total surface area to pressure wash.
Soil Level
0 = Light, 1 = Moderate, 2 = Heavy soiling.

What each result means

Recommended PSI
Safe pressure setting for this surface type.
Water Usage
Estimated total water consumption at 2.5 GPM.
Detergent Needed
Ounces of pressure washer detergent required.
Estimated Time
Total pressure washing time in minutes.
Estimated Cost
Professional pressure washing cost estimate.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Surface Type = 0, Area = 500, Soil Level = 1 = 3 input(s) provided
  2. Calculate Recommended PSI
    Recommended PSI
    3000 = 3000
  3. Calculate Estimated Time
    Estimated Time
    89 = 89
  4. Calculate Water Usage
    Water Usage
    222.5 = 222.5
  5. Calculate Detergent Needed
    Detergent Needed
    62.5 = 62.5
