Still have that one box of corn starch you bought for one very specific recipe (homemade thin mint cookies, perhaps?), lingering in the back of your pantry, taking up valuable real estate? It's not an ingredient we turn to often, but now we know what we can do with it between stir fry nights. You guessed it: Clean! Here's how. While we knew about the myriad uses for baking soda, we weren't aware there were so many for corn starch. From cleaning windows, polishing silver, fighting grease stains on fabric and leather, keeping your ironing nice and crisp (yes, even with powdered starch), and even de-sticky-fying playing cards, corn starch is a pretty good go-to household cleaner. And, given its food-based nature, it's very safe for use in households with kids and pets.
