I have to clean a white metal building with small mold spots. Can I use a truck wash, Windex, or store bought 6% Clorox through an x-jet? It is 2900 sq ft of siding 12 feet tall. Worst-case scenario is that I have to scrub up 12 feet. Best-case scenario is I can touch-free spray wash the gray mold spots off.
