 to get mold to grow. But what I would do is I'd pull the refrigerator out, I'd spray that area, saturate it with a 50-50 mix of bleach and water, let it sit, and maybe one more spritz of clear water just to clean, take the odor away, and then I think you'll be good to go. Just keep an eye on it. All right, now we've got one here from Ed who says, we have a deck that gets partial sun during the day, and it has a greenish moss covering it. How do we clean that to get rid of the moss and prevent it from coming back?
