Just finished washing a typical vynil house. Home owner called an said there are brown streaks in areas. I believe i have seen them before. Almost looks like residue from rust or window. Could it come from allowing chemical to dry on siding? Sorry i dont have any pics. Any body know what it comes from? I used simple cherry an SH in that mix?
I have found if you can wash in the opposite way that the vinyl was laid you don’t seem to get water Into the vertical joints and less “bleeding” occurs

So its been raining for 2 days an the lady said it hasnt helped an there is brown dirt all over her house. She will send me pics soon but im not sure why it would be that bad.
looks like the vinyl is discolored… I would go with water from behind but it wouldbe more drippy looking, there are some areas where the discoloration is to flat and even, doesn’t follow the normal routes you would expect if it was water from weep holes… I would spot treat an area again and see what happens… does the brown rub off with a rag and soap - does the white?
Initially I was going to say it was water that got behind the siding and is dripping out of the weep holes until I looked at all the pictures and saw the areas where it’s discolored in larger sections not consistent with water dripping.
The first questions that come to mind are this:1-Was the house like this at all in any areas before you cleaned it and if you have some before shots take a close look. 2-does the siding color come off on your fingers if you rub them on the siding. If so the paint maybe oxidized(reasons like this is why we don’t do aluminum houses but rarely is this a problem with vinyl).
Then I would do a spot clean on this house in an affected area to see how it comes out.
If this problem wasn’t there before you started and test cleaning done on an affected area doesn’t solve the problem then hopefully you have liability insurance because it may come down to her putting a claim in against you.
Went back to rewash it an it was squeaky clean. Guess it was just runoff. It rained for 3 days straight after those pics… Thank God it wasn’t serious. Here vinyl had larger than normal gaps an was clearly improperly laid. It was almost impossible to not get water behind the siding. Thanks for all the help guys
Same here…glad to hear it worked out for ya. Those were some big stains from water dripping out of the vinyl. This story had a happy ending thank goodness.
I have seen homes that looked similar to this, and what had happened is the home owner had it washed by a washer using high pressure and they had removed
some of the oxidation on the vinyl ,very noticeable when house dried. I am in no way suggesting you used high pressure.I would check to see if siding oxidized,
ask owner if previous house washer soft washed or was a high pressure blaster.After checking for oxidation, I personally would rewash with under 100 psi, making sure sodium hypoclorite fresh,use bobs elemonator 1 oz per gallon downstreamed and see how it looks rewashed. Best of luck.
