I found an old magazine in my desk and flipped through it this weekend. It was a 2008 Women's Day.
In it is this quick little article by Janet Sobesky:
5 uses for cornstarch
1. Slide rubber gloves on in off with ease after you sprinkle some inside the gloves
2. Can help your feet with blisters and smell -- sprinkle some in your socks and shoes
3. Use it on a damp cloth then scrub the grease spots on your kitchen wall
4. (Not sure how you would do this) -- Use it to stop the squeaks in your floor by sprinkling it between the boards
5. You can also use it to get knots out of strings etc. Sprinkle some on the knots.
Do you have a use for cornstarch that's cool or interesting?
