Pressure Washer PSI
 

In purchasing a pressure washer what PSI would I need to do a decent job for the outside of my vinyl sided house and driveway? Thanks in advance.

2200 and up

The lower the better because the high pressure will actually drive the dirt into the surface. Also, make sure you don't use any form of chlorine. that will ruin siding for sure.

Just purchased a 3000 psi, it came with a surface cleaner. The surface cleaner was amazing for the sidewalk and driveway. I found it takes a strong spray to get the algae and mold off the house. We also have a white fenced in back yard. I wouldn't buy anything less then a 3000 psi, or you'll be frustrated and it will take forever !

Also be aware of gallons per minute rating, 2 gallons per min can't handle a decent fan tip. Look for 2200psi and up, 4 gallons per min flow rate

I use a lower PSI (1700) but I use a good quality prewash and this works very well. While I have no personal experience, I have heard stories of high pressure units actually damaging vinyl siding.

A standard gas powered that has a minimum of 2200 psi.

Hints: standard bleach cut with water (about 1/16 bleach to water works great. Do in sections so water does not dry before pressure washing. Note: wash in spring and fall with cooler temps. Note: There are several options most of which use bleach anyway.)

Rinse with plain water or painted surface may bleach oit in the sun.

NEVER start PW without first turning on tge water. Tge pump can not run dry or the impeller will fry.

If yoir pump goes bad, buy a new pump and install yourself. They are about $100 and simple to install.

Windows
 

Be careful on windows the pressure can break the seal on double pane windows. You won't know it for a few months when the glass starts to fog in between the panes.

B E very careful at high pressure and keep noozle at a distance from vinyl surface , I have seen wood siding destroyed by that pressure.

I just researched greatly before buying as I have a large brick paved area and walls etc to clean. You need a gas pressure washer that is 2,900 - 3,300 psi range for sure. All pressure washers come with varying nozzles depending on what you are cleaning, so not to damage areas like fencing as opposed to stonework. The round surface cleaner is a must addition for large areas. Plenty of video 'experts' to see on YouTube.The Best Pressure Washing Videos of 2018 - YouTube

Pressure washer PSI
 

I've had several washers and for my private and professional use 2800 is minimum . Sam's has a good one in "Black Max" unit

1700 psi at Harbor Freight - about $100

I would hire someone. A few years back we looked at a home to buy and 5 windows had damage from a less than quality power wash job. We used John McIntyre to power wash our CYV, they did excellent work and it was only $65.

Pressure washers come with various nozzles for different situations. I think that as long as you use the correct nozzle, you'll be ok. As usual, be sure to read the manual.

Use gasoline powered pressure washer
 

We bought electric power washers from Costco twice and had to take both back. They were only used once or twice before the hose broke and could not be replaced. And they were underpowered.

Our gas powered washer is more powerful and reliable. It comes with several nozzles designed for different uses. It has the power to blast the dirt off of concrete and can be set to wash your car or your siding.
