Before you purchase any High-Quality pressure washer, you should know what you want to use it for and, of course, know its PSI. PSI is used to measure the washer’s water pressure, and it stands for pounds per square inch.

The PSI is determined by the strength of the chemical bond between the dirty surface and the stain. This means the stronger the bond, the higher the pressure required to remove the stain.

Now you know the relationship between the PSI and the cleaning task at hand. Furthermore, keep in mind that whatever surface or area you plan on pressure washing determines the PSI to be used.

How Can You Choose the Proper PSI For Your Pressure Washer?

Knowing the pressure washer to buy is quite a small feat but knowing what PSI is proper is no small deed.  Here is a summary of the suitable PSIs for different tasks to make it easier for you.

  • 1,000 to 1,900 PSI: For home-related tasks and automotive clean-ups.
  • 2,000 to 2,900 PSI: This is of average strength and can be used on heavier domestic tasks.
  • 3,000 to 6,900 PSI: Contractors professionally use these for industrial or business-related works. They are fuel-powered.
  • 7,000 to 50,000 PSI: These are used on large equipment and structures because of their super-high pressure.

Pressure washers that run on gas are usually above 3,000 PSI, while the electric ones are between 1,300 to 2,900 PSI. This differs among washers, but you can easily choose the right PSI for your task with the summary above.

A powerful PSI pressure washer like 3,000 to 50,000 PSI works effectively in getting rid of stubborn stains such as mold, strong bubble-gum stain, dried excrement, graffiti, dried mud, and so on.

Although using a strong PSI pressure washer for light-duty tasks is not advisable, some cases require it. In such cases, do well to stick to not more than one or two ratings higher and make sure you stand not too close to the surface being washed to avoid damages.

In addition to the PSI, you also need to pay attention to the different pressure washer ratings. These ratings include light-duty, medium-duty, heavy-duty, extra-heavy-duty, and multi-duty.

As the name implies, the light-duty pressure washer (1,300 to 1,900 PSI) is for light tasks that don’t require much force. In contrast, a medium-duty pressure washer (2,000 to 2,800 PSI) works for driveways, fences, sidings, and walkways.

Heavy-duty washers and extra-heavy-duty ones (2,800 PSI and above) are great for business-related purposes such as washing homes, removing graffiti, and prepping for painting. On the other hand, multi-duty washers are for multiple purposes, of which its PSI can be regulated based on the task at hand.
