We are downsteaming, Its around 4% to 7%. its just in certain areas.This is our second house with this mix, we had no problem with the first house.Question can the problem be the vinyl and that there so much dirt build up over the past 5 years.Just need some ammo.....also my ducks in order before we talk tomorrow.

is the side of the house in the sun all day becuase that plays a part and also if the algae has been on there for 5yrs then most likely the algae caused the problem not you.

12.5% straight up might be ok with a low draw injector. But even with a high draw, like a Super Suds Sucker, it shouldnt cause fading. When you say fading; is it a chalky residue? What type of surfactant are you using?

the only way you could of done any damage is if you used pressure, if the fading appears where you pressure washed then that could be a problem, but if the fading is completely uniform, you didn't do it, we never pressure on siding, non at all.

through our experience the strength of SH has no effect on vinly siding!

 as long as you didn't mark it up just leave it alone, your only there to wash the dirt, mold and mildew, uhless you want to spray paint it??? you know vinyl siding can be painted.

Its oxidation, tan,clay and light blue is the colors we have noticed with it the most, espeacially the first 2or 3  panels  close to the ground.  the only thing you did wrong was not pay close attention to detail when bidding the Job .

100% agreed. We have had problems with the tan and clay this year like no other year. Yes it is oxidation...but what can be done to get rid of it?

Yes I also agree that it was there before you started the job...so technically it is not your fault, but they didn't see it before you were there so...now it is your fault.

It happens, I let all customers know this ahead of time if the siding is old, in the sun, or poorly maintained...

I use 12.5% SH with a Super Suds Sucker all day with no problems like that.  Once before I did & learned by my mistakes.  The problem is that the house was not rinsed enough.  What you are seeing is dried SH on the house.  I still see that today when I spray the ceiling of a covered area.  You can rinse, rinse, & rinse and a trace amount is still there.  As the water dries on the ceiling, the water drops look a lighter color.  After they dry up a day later they are gone.

Vinyl oxidation needs more than just bleach. Use a detergent/surfactant specifically made for house washing that can be mixed with bleach.

I recommend either

Sunbrite's - Power House
Envirospec's - Emulsifier Plus
Pressure Washer Products - Streak Lightning
Pressure Tek's - Simple Cherry
Power Wash Store's - Blue Voodoo

If it still looks oxidized, then you may have to add a little hydroxide based detergent and/or brush the oxidized areas.

I found an inexpensive Vinyl sealer that restores the vinyl much like Flood's Restora (which is discontinued)

Call me if anyone is interested in this new product I've found that can make a big difference in the quality of your work, adding beauty and longevity to your customers vinyl.

Pressure washing is my main business, unforgivably it's sulfur chalk due to old weathered vinyl siding.
Use 4 percent - 7 percent chlorine mix (water) and soap, and keep wet while you brush manually the siding down.....if you skip an area this is what you see ....white spots of hell.... from my experience this is the only solution to clean a house that has been oxidized from good ol mother nature... Keep in mind wet on wet and rinse from top to bottom ....no pressure necessary........(note:) keep away from aluminum siding ...because they are usually always oxidized..threw the manufacture paint.. good luck
