The psi and gpm determine the cleaning capacity of the pressure washer.
Pressure washer psi for siding.
Never start off on the highest pressure setting.
A pressure washer can quickly ruin vinyl siding by cracking it with the high pressure stream of water so it s necessary to know which pressure level and nozzle to use.
The psi is irrelevant for this job because the nozzle and how far you hold the wand from the surface will determine it.
If cleaning the vinyl siding or any part of your house is the only reason why you opt for a pressure washer then you might want something with at least 2 3 gpm.
Most electric pressure washers create 1300 1700 pounds per square inch of pressure psi with a water flow of 1 5 gallons per minute gpm but experienced contractors recommend between 2000 and 3000 psi and a flow of at least 2 5 gpm to clean dirty concrete effectively.
Commercial grade pressure washers are included in this group starting at 3100 psi.
All the pressure washers with 2 3 gpm have at least 2 600 psi.
Usually concrete flooring would be around 8 inches so a psi 3500 to 4000 is good enough.
With a pressure capacity of 2030 psi it is a powerful pressure washer which works very well in cleaning the siding.
To rent or buy.
Pressure washing machines can be bought online or in retail stores or rented from local equipment rental companies.
Pressure washers with a high psi will clean deep stains more effectively than machines with a lower psi.

Pressure washers with 2 3 gpm usually have a range of 2 600 psi or more.
These pressure washers put out 2800 psi and higher at 3 to 4 gpm.
This pressure rate is not too weak and not too strong to clean up the dirt or the grime on the concrete patio or driveway flooring.
However we observe that a psi of 4500 is ideal for typical concrete flooring.
Starting low and gently working your way up is the safest bet.
My siding used to be dirty but the pressure washer has made things easy.
Pressure washing machines can range from 1 200 psi to as high as 2 700 psi.
A standard gasoline or electric washer with a pressure rating around 3 000 psi should provide more than enough force to effectively clean even hard to reach places.
The motor generates the necessary pressure to remove all debris from the siding.
3 increase the pressure incrementally.
