Pressure washer shoppers often ask how much pressure they really need from a pressure washer.
The pressure put out by a power washer is measured in PSI (pounds per square inch), and the PSI requirements can vary based on what you're aiming to clean.
For example, it'll take a lot less pressure to clean dust and salt from your vehicle than it will take to clean oil stains from your garage floor.
Another factor that's equally as important, but not often considered, is the gallons per minute rating (GPM). This measures how much water your pressure washer puts out per minute, and more water equals faster cleaning.
How Much Pressure Does it Take?
Learning how much pressure is required to successfully clean different surfaces, materials, or objects will help you determine what size pressure washer you would best benefit from.
Remember, if you're never going to exceed 2500 PSI, then you can save some money by choosing a 2600 PSI pressure washer over a 3000 or 4000 PSI pressure washer. The added power might make you feel like a stud, but why pay for it if you'll never use it?
Also, knowing what's required to complete different tasks will help ensure you select a power washer that's powerful enough for what you are cleaning.
