The psi is irrelevant for this job because the nozzle and how far you hold the wand from the surface will determine it.
How many psi needed to clean siding.
There are also professional cleaners that will do the cleaning for a fee.
You will want a power cleaner with at least 2 3 gpm.
It is recommended that you get a machine with a pressure level of around 2500 psi with around 2 0 gpm.
Vinyl siding is one of the easiest materials to clean with mild detergent moderate pressure a white fan tip.
On the contrary this pressure is too less to clean parking areas stained with tar.
Pressure washing machines can be bought online or in retail stores or rented from local equipment rental companies.
Fortunately pressure washers have made cleaning hard to reach places like this easier and safer than ever.
More pressure is certainly useful in some situations but it s also more dangerous.
For around the yard chores like stripping a deck degreasing equipment or washing siding 1 300 to 1 600 psi is plenty.
A machine with a psi of between 1 300 and 1 600 is desirable in cleaning most siding materials including vinyl siding.
However keeping the second story siding clean can be a difficult task without the right equipment and using a ladder or scaffold to reach high places can be dangerous.

Unlike cars you won t scrape away the finishing of the wood furniture.
All pressure washers can rip through flesh at close range and more pressure increases the potential hazard.
It would need somewhere around 4 000 and 7 000 psi.
Heck some might even choose 3 stories if they could.
This pressure is more than a garden hose.
These pressure washers put out 2800 psi and higher at 3 to 4 gpm.
Commercial grade pressure washers are included in this group starting at 3100 psi.
To rent or buy.
A 1 500 psi unit might indicate a high pressure to a homeowner for cleaning decks and siding.
And it uses a fair amount of water.
A pressure washer needs water too.
A washer with a psi rating of 1000 to 1500 is usually quite sufficient for washing siding.
That s good enough to wash away the sticky molds and the stubborn grime that you ll find even in the inner creaks of your wooden furniture.
Anything more than 2000 psi isn t necessary if you are pressure washing at a higher psi watch your window seals the siding sliding down out of position.
Most people would choose to have the extra space of a 2 story home.
If you are truly that desperate to clean the siding off in mid winter then you will need to make the effort to deal with turning the water on and off anyway.
