That looks fantastic. What F9 mix ratios and was it a hose rinse or powerwasher?

WOW Craig we could never get that off in 20 years of cleaning. That is an incredible find!

Thanks Gregg. He used F9 to water at 2:1 and is trying a 1:1 tonight. Just spray on, dwell 3-5 mins and wash off with power washer.

Thanks, AC. Our Applicators are finding more and more uses for F9 everyday. I've used it on stains like these in the past and just forgot about it. Between F9 and another cleaner we make, we can remove just about any stain on anything (except mold and real hard water on windows.) This has become quite a venture. Going to be getting on F9 here full time very soon.

Wonder if it would work to renew gutter faces?? Would be great to have a "spray on, rinse off" with no brushing.

Any remedy to get the haze off of glass?
Also, what is the minimum temperature that we can use this at? Will it work for us during the wintertime?

I have some guys trying it out on this. Will know soon. Just need to make sure not to get it on tinted glass and be careful around all glass. Some glass it's fine, others it leaves a haze.

Mark,
If it's not frozen, it will work. I've used it in 115 degree temps too.

We used F9 on a crazy application today. We cleaned a home with brick and right by the front door, the old coal fired furnace for decades leaked coal soot up between the steps and the brick facade.
Nothing touched it, so being a creative risk taker, I put F9 on it. We let it dwell 5-10 minutes and that stuff started to pull the coal soot out of the brick. I did not expect that to work, but it did.
We will follow up with pictures soon, but the homeowner was super happy to remove that right by her front door.
I like everyone posting on the forum as to what we are using your product on Craig!
We also did a test area on some heavy mineral streaks from a limestone wall cap above Dryvit, and it really looks like it will remove all of the stains.
