While cornstarch is great helper in the kitchen, it’s uses extend far beyond food. Take a look at some of the household uses you can put it to:

1. Streak-Free Window Cleaner: make your own window cleaning solution by mixing 2 tablespoons cornstarch with 1/2 cup of ammonia and 1/2 cup white vinegar in a bucket of 3-4 quarts of warm water. Mix this and put the solution in a spray bottle (it should look a bit milky). Spray cornstarch solution on windows, then follow with a warm water rinse. Wipe dry with newspaper or lint-free cloth.
2. Pest Control: mix together equal parts cornstarch and plaster of Paris to sprinkle into cracks and crevices around the home. If pesky cockroaches are hanging around, they will eat this and die.
