A quality commercial pressure washing job requires matching PSI and nozzle selection to the specific surface, with precisely calculated chemical dilution for effective, damage-free cleaning.
Pressure washing operators sometimes use excessive PSI or incorrect chemical ratios for a given surface, causing damage that could have been avoided with proper testing and calibration.
Why This Happens
More pressure and stronger chemicals can seem like they'll clean faster, but different surfaces have very different tolerances, and mismatched settings cause damage that's often expensive or impossible to fully repair.
What's Inside
This checklist is interactive, click to check off items in your browser, plus printable if you'd rather bring it to the job site, and it covers nozzle orifice sizing, downstream injectors, and PSI tuning specific to commercial pressure washing, distinct from car washing or detailing checklists.
Quick Tips
Test a small area before full application.
Match PSI to the specific surface material.
Calculate chemical dilution precisely for the job.

Frequently Asked Questions
How do I know what PSI is safe for a surface?
This depends on the specific material, softer surfaces like wood siding need much lower PSI than concrete, testing a small area first helps confirm the right setting.
What does a downstream injector do?
It draws and mixes chemical into the water stream at a set ratio, confirming it's drawing correctly ensures accurate chemical dilution for the job.
Why test a small area before the full job?
It catches potential surface damage or chemical incompatibility before you've committed to cleaning the entire area.
How does nozzle orifice size affect the job?
Smaller orifices increase pressure concentration, larger orifices spread it out, matching orifice size to the surface and job type affects both cleaning power and safety.
