There are numerous non-baking uses for corn starch. One such use is cleaning grease. For example, let’s assume your kitchen walls and backsplash have grease splatter on them. Putting some corn starch on a rag and rubbing it into the grease will lift and remove those unsightly splatter marks. Another helpful benefit of corn starch is that it makes short work knots. If you run into a stubborn knot, whether on shoelaces or rope, corn starch will help you loosen it up. Simply sprinkle a little bit of corn starch on the knot and rub it in. The corn starch works to reduce the friction in the fibers of the rope, thereby allowing you to easily untie those stubborn, tight knots.
