Removing Mold and Staining on Older Kenmore Fridge?My husband and I have got a fridge that's about 15 years old. It's in great working order, but the side of it that has been toward the wall since we moved in has scuff marks, mold, and what appears to be some oxidation (the white paint is not only coming off, but the outer wall is just beginning to rust!) What can or should I use?
