I went back and used a small amount of Elemonator and water down streamed then rinsed. It helped a little but I could still see the stains. So I used 1/3 SH, 2/3 water and Elemonator, did the whole house, rinsed like hell and left. I checked it this morning and it's all clean. My only thought is that it was 90 degrees and sunny and my guy let it dry on the house. So when he rinsed it didn't move the dirt running down the siding.
