Hello all, I am fairly new to the business and had a very strange result after my last house wash. I’ve done a few houses and have not had this problem until now. Side note, the house looked perfect when I left. My procedure is 10% sh and the recommended amount of elemonator in a jug fed to an X-jet with a 10:1 proportioner (1% mix) there are 2 issues present in the picture. The first being the dark run lines, I attribute this to dirt behind the siding running out and drying, I plan to first try lightly misting it in hopes that will get rid of it, If not, I plan to use a light mix and rewash. I was also informed to only spray with the siding overlap, something I didn’t hear mentioned when learning the ropes. The second problem is what appears to be oxidation on the left half of the wall pictured. I made sure to use low pressure, wash from a distance, and rinse before it was dry. It wasn’t a very hot day but wondering if I should have cooled the siding before hand?
To sum it all up, my questions are:
- How would you go about removing the “run lines”?
- Is the left side of the siding in this picture oxidized? If so, what did I do wrong and how can I fix it.
PS. I did the finger swipe on the right half of this side of the houses siding and there was barely any dust, didn’t think to swipe the left side cause I couldn’t imaging why that would be different.
Thank you, Evan
