[Parent post: "Window sill stain"] Anybody know where this stain came from? I don’t think I have a leak but occasionally can these yellowish brown stains on the window sill. --- Condensation running off the window glass. Common in winter when temperatures are very cold and humidity inside is high. Worse if the windows are old (have low R value) or have lost the seal between the panes.
