How to remove run off stains on a house

I was pressure washing a home the other day and it had these run off stains on it from wood and from shutters as well. I have run across this a couple times before and have tried everything to remove them. Does anyone have a product or a suggestion on how to remove them. I don't' even know if it is possible.

The first picture looks almost like the stain was pulled out of the wood by the house wash mix. If that is the case, maybe put some more house wash mix on a brush or rag and wipe down the stain.

If the window stains are rust (very possible), I would recommend the F9Barc.
 
Some of that looks like rust, some looks like the wood stain runoff. F9 BARC will easily and quickly remove the rust. I'm not sure about the other stains but it might work on those too. You'd just have to spray it on then pressure wash it off.

Shane and Trudy are personal Friends if mine and good people Craig, please take good care of them.
 
Is that house dryvit? Be very careful with an acid. It will take the stain out but it can also discolor or bleach out the dryvit. I know from personal experience. Test it somewhere inconspicuous.

I guess it depends on the color itself. I have used the Saferestore on lots and lots of houses that are stucco and dryvit and now the F9 and have had no color bleaching issues, maybe the color was already badly oxidized first?
 
Thanks Ron!

The stains from the wood area were present before we started the job. So I know that one is not from the house wash mix run off.

While at the job I did try Straight SH and washed it off after 5 minutes dwell time and it did nothing. After that I put on the clear pink stuff just on the stain where the wood is and it did nothing as well. I have some F9 and will go back and try on all stains and see what happens. Thanks for all the response. I will keep you posted after trying the F9.
 
The stains where the wood is might be easier to re paint?
