PSI – Understanding Pressure, Power and Cleaning Results
When working with PSI, a unit that measures pounds of force per square inch, used to judge water pressure in cleaning tools. Also known as pounds per square inch, it tells you how hard the water will hit a surface and how deep the clean can go. In plain terms, higher PSI means more force, but that doesn’t always equal a better outcome; the right level depends on the job, the material and the safety limits.
One of the most common applications of PSI is Pressure washing, a method that blasts water at high pressure to strip grease, mold and grime from driveways, decks and building exteriors. The technique relies on matching PSI with the right nozzle and flow rate, otherwise you risk etching paint or leaving residue. Window cleaning, the process of removing dirt and water spots from glass surfaces often uses a much lower PSI to avoid cracking tempered glass, and many professionals now use water‑fed poles that combine gentle pressure with purified water. For those thinking about turning cleaning into a career, the Cleaning business, a venture that offers services like pressure washing, window washing and oven cleaning to residential and commercial clients hinges on understanding PSI settings, pricing structures and equipment choices. Even something as specific as Oven cleaning, the deep removal of baked‑on grease and food residue from kitchen ovens can benefit from a low‑pressure steam clean that loosens debris without harsh chemicals.
