Magic Cleaner.. 2 oz. Dawn, 4 oz. bottled Lemon Juice, 8 oz. White Vinegar, 10 oz. Water. The secret is to spray on surface, let sit overnight (or longer) and then wipe with clean, wet cloths to remove residue. *In the oven, do NOT use heat, just spray, let sit, wipe clean. *For showers, just spray, rinse and if you like the shine, wipe with dry towels. *The secret on whatever you chose to clean is to let it sit, then rinse off the residue. Amazing stuff!
