How to Determine the Appropriate PSI for a Pressure Washer

PSI or pressure per square inch, is one of the most important factors to consider when choosing an industrial pressure washer. The appropriate PSI for your pressure washer will depend on the specific needs and applications of your cleaning project. Factors such as surface type and level of soiling can influence PSI selection, so it is important to carefully evaluate your cleaning requirements before making a decision.

One common approach to determining PSI is to start with a lower PSI setting and gradually increase until you achieve the desired results. This allows you to fine-tune PSI settings based on surface texture and other factors. For example, high PSI may be suitable for heavily soiled surfaces with little surface texture, while lower PSI may be better for delicate or textured surfaces that require more gentle cleaning.

Another consideration when selecting PSI is the type of detergent or cleaning solution you are using. Some solutions may require higher PSI levels in order to be effective, while others may work better at lower PSI settings. Experimenting with different PSI options can help you determine the best setting for your needs and achieve optimal results.

Ultimately, choosing PSI is a matter of balancing several factors such as surface type, level of soiling, and detergent choice to find the setting that works best for your specific cleaning needs. With careful evaluation and experimentation, you can select the right PSI for your pressure washer and get great results every time.

Below you’ll find a few PSI guidelines for surfaces that are commonly washed with a pressure washer:

Car or Truck

Recommended PSI Range: 1200 – 1900 PSI

Patio Furniture

Recommended PSI Range: 1500 – 1900 PSI

Sidewalks

Recommended PSI Range: 2900 – 3200 PSI

Fencing

Recommended PSI Range: 2000 – 2800 PSI

Driveway

Recommended PSI Range: 2900 – 3200 PSI

Heavy Stain Removal

Recommended PSI Range: 3300 + PSI (if surface will not be damaged)

If you are unsure which PSI setting is right for your pressure washer, it may be helpful to consult with our experienced professionals at RJP Hotsy who can help you select the best PSI level based on your specific needs and application requirements. With the right PSI selection, a pressure washer can be more efficient and get the job done right.

						The group over at RJP Hotsy is awesome! Very knowledgeable and helped us build our 8 gallons per minute rig set up for HotWash Pros in no time.

						Krown undercarriage spray service was overall a very good experience and I recommend it. They let me watch and it was fairly quick but thorough and they also pressure washed my truck after.  Before you arrive for your appointment, it would be a good idea to call them to confirm your appointment is still on the schedule to avoid what happened to the other guy who commented below.

						RJP Hotsy has been a life saver! They are so incredibly knowledgeable and have worked on pretty much all of our powerwashing equipment. They built 2 of our rigs, and are now outfitting our cargo van and our box truck. They have come through with equipment for us on short notice when we’ve had a breakdown at a job. I highly recommend RJP Hotsy for your equipment needs!

						Good place for a professional power washer to buy equipt and supplies as most things are higher end and chemicals and solutions are sold in bulk concentrate although homeowners could probably get a part there for their power washer repair if need be. But they have nearly everything there and are very knowledgeable of the products and very helpful. So if you're not hours away from it it's a good place to check out at least if you're in the market for buying things as you can explanations and ideas and handle the items and see what they are before purchasing as opposed to just buying things out of a catalog.

						As the owner of a pressure washing company, our equipment is the lifeblood of our operation.  I contacted the staff at RJP Hotsy in the morning regarding my hot water pressure  washer repair. They responded promptly and came to my shop within a few hrs.!  Ryan and Connor took machine apart, diagnosed the problem,  and had us back running in a couple hrs. Great service, will definitely use them again for other repairs.
