sorry it took me so long, but my testing is now completed. After one year of testing, I have found that both Windex and 409 will make your natural stone lose some luster and dept to color. The testing was done on a black granite that was place next to a window, in the past year i have use lest then half a bottle of each chemical. when compared to the area that I only use plain water, there was a noticeable deferents in the finish.
