[DynamicDetails]

How do you get the Red Clay off of vinyl siding. The house wash mix wont take it all the way off? thanks guys

Oxalic acid. Not sure how you're applying, but for a straight mix that should work: 1/2 cup to a gallon of water. Use hot water for easier dissolving. You may need to adjust your mix,but oxalic will work.

Applying W/ Delavan FATBOY. I mix my house wash in a 200gal tank.

Unless it's really all over the house, I generally find a typical pump up to work for this application. I usually see red clay from the foundation up a few laps of siding. Usually one or two fill-ups in a pump sprayer will be enough.

Hey thanks a lot guys...The pump up sprayer is a great idea...I have one more question where do you get the Oxalic acid from?

I get mine from Univar. It is also sold as wood bleach sometimes and also as boat bottom cleaner. Look for a product called Slimy Grimy. Buying it in bulk waaaaay cheaper though.
