Mix ammonia and warm water in small bucket. If you need more or less of the solution, remember to use equal parts of both ingredients.
Wet the clean washcloth into the solution.
Apply the cloth to the stain, rubbing vigorously. This will remove most stains from the refrigerator, although they might not all come out at once.
Try a Borax solution for extra stubborn stains. Make sure to wear rubber gloves when working with Borax.
Mix the Borax with the lemon juice in a small bowl.
Dip a clean washcloth into the solution and apply to the stubborn stain.
Dry the stained areas with paper towel when finished. The stain should be gone.
