I found a box of cornstarch hidden way in the back of my cupboard, and it was already past its expiration date listed on the box. Not wanting the stuff to go to waste, I looked up some corn starch craft recipes and found a whole bunch!
Finally, if you visit the Argo/Kingsford’s Corn Starch FAQ page, click on “Household Use” and scroll down for suggestions on using corn starch to wash windows, clean pots and pans, absorb grease and perspiration, relieve sunburns/rashes/hives/poison ivy, and use as a baby powder.
P.S. I was also told that despite the expiration date, the shelf life of cornstarch is virtually indefinite. Its thickening power doesn’t come from a chemical reaction, so corn starch won’t lose reactivity over time. But it’s best kept in a dry cupboard away from direct heat, and it can be invaded by bugs, so it should be stored in a tightly sealed container. (Storage in a refrigerator or freezer is not recommended due to the moisture from condensation.)
