So I tried the AllBrite (Butyl Degreaser) as you said jeff, (should I try to find some Purple Power/Castrol Super Clean) it didn't do anything but foam just a little bit and was a bit slippery, but other than that, nothing.
Now to what Len said about the Weather Wrap. That could be a possibly since I have also noticed just earlier that also the foundation (brick part under the vinyl) has red streaks on it now, which leads me to believe no oxidation, but more like solution went behind the siding and basically washed away the color on the weather wrap.
But why does Solution get behind the siding? Leads me to believe that the Hardie Plank isn;t installed correctly. I found this little exerpt:

An independent investigation of dozens of homes in Houston, Texas, which were fitted with Hardi Plank siding, found that at least 90% of them were improperly installed. In many of these cases, the warranty on the materials was likely voided.

Given, that comes from a Siding Company website, but there still has to be some truth behind it.
I really dont know what to try anymore. Wouldn't the Melamine not only get rid of the red streak, but also the actual paint of the house?
