The finished product oftentimes looks different to the one who cleaned it. A week ago my son put a video on FB of him cleaning a white sofa that was chocolate brown before cleaning. It had a rather tall nap to it that made the freshly cleaned white fabric look dirty depending on the nap direction. He was proud because he saw how much dirt he’d removed, but I’m certain many thought it looked terrible. He isn’t ignorant, and he’s a good cleaner. He just saw it differently because of his perspective.
