I have to quote a customer on a house wash that has Hardie Fiber Cement siding.
What should I use to get the rust off the lower portion without taking the finish off? I have used F9 BARC before but only on concrete.
Also, notice the color differences in the finish on the upper part of the house. Could that be oxidation or just a bad paint job? I really did not get any oxidized paint off with the wet finger test on a lower portion.
Any advice would be appreciated. The north side has quite a lot of mold that I know we can get off with house wash, but I do not want to have to repaint this guys house.
