OK, so this one isn't so much of a miracle as a basic chemistry lesson. For stubborn stains on your Formica, blend a pasty mix of water and your choice of powdered cleanser. Depending on the size of your stain, you may not need more than a few tablespoons of water. Once you have your paste, smear it out over the stain, covering it completely. Let it fully dry out and crust over, and then remove it with a warm wet washcloth, being careful to not let the abrasive nature of the dried paste scratch the surface. A quick wash down with some soap and water and you should be stain-free.
