I was tied up all yesterday afternoon or i would have responded sooner.
Owned a commecial & residential pressure cleaning biz for 5 years...
I would recomend keeping all house washing (brick/vinyl/whatever) below 1000 PSI.
You can use dif. tips on the end of your wand to drop the pressure, this is the best way to do it. I am not refering to dif. degree tips...thats something else. I have a chart somewhere that will tell you what tip will give you what pressure on whatever PSI pump you are using. If i can find it i will post it.
As for what to use....if you dont use something besides water you are doing the same thing the homeowner can do...
Would you wash your dishes without soap..."hay it looks clean".
I would use (in laymens terms)..
Pool Clorine (liquid & at least 10%)
Some low foaming soap or the like.
and some rinse aid
Mix 1 gal clorine, some soap (depends on the kind as to how much), and a few ounces of rinse aid into a 5 gallon bucket...fill the rest with water and using an X-Jet spray that on the house (2 sides at a time) come back and rinse it using LOW PRESSURE. SHouldnt take long at all.
2000 SQFT brick house (1 story) should only take about 45 mins or less.
(maybe a little longer if you havent done it 1000 times)
Dont forget to charge extra to clean the gutters (the outsides).
If they have black streaks on them (like a lot of the white trailers get) look for something called "Gutter Shock" its the best stuff for that (as well as many other things).
Any questions let me know.
