My first big job. Need advice

I'm cleaning a large colonial for my virgin run.  I sprayed from the gutter line using Apple Cider Sauce.

15 gallons 12.5 SH
25 gallons water
5 lbs TSP mixed the night before
64 oz isopropyl alcohol

At the site I mixed the TSP and isopropyl in the Mix. I came back a week later after a rain storm as I did not rinse the roof. The roof was noticeably much cleaner and brighter. However the black mold is still there and since the background roof is cleaner the black mold streaks are more pronounced. Any suggestions for round 2confuseconfuse

It sounds like you didn't have enough dwell time for the mix to oxidize the stains completly. Maybe try substituting the tsp for 1/2 bottle of dawn...mix on site like normal. Just don't use antibacterial cause  it will gas up...

there is nothing wrong with  your mix ratios,  except you never mention a surfacant
how feash was the SH ? what strength was the Sh?

and yes your profile is part of the rules of the board

I had similar issues with a supplier I was using for SH. As the weather got colder, the SH my supplier was selling me was getting even weaker. I was respraying every time. I'd check to make sure your SH is not weakened.

I would agree on weak SH. I have had some issue as well with stale SH not cleaning to its full potential.

Like Dave said, without a surfactant your mix did not stick on the roof and most of it ran off.

Thanks for the input guys. I first stated on this site a year ago only to find out more about roof cleaning, back then I was told by a contractor that the black lines on my roof were the result of the sand washing off and the asphalt showing through. The contractor was unaware that I had replaced the roof 9 years earlier after getting the same story. Armed with a garden hose and chemical sprayer for trees, I experimented with many bad chemicals until I found this site. I finally bit the bullet in September this year, built a rig and started experimenting on friends houses. I plan to start my LLC in March. I'll update my profile tonight. Thanks for the input. Also I did have a bottle of dawn in the mix. I found the box the SH came in, the mix date was 9/2, I sprayed on 11/15.
