Ok, so we started on that house with Hardi Plank siding, as suggested, I used the same mix as I did with vinyl. 1 gallon 12%, half a gallon of allbrite, and 3 1/2 gallons of water.

Well, here is the outcome of one side:

It seems to be very light color in some places, and hace very light red spots everywhere. It does come off when scrubbed really good, but I was wondering if there is anything else I could try?

Thanks. What does it look like to yall?
