I love making homemade cleaners to naturally clean and deodorize my home. Unfortunately, I’ve found that online cleaning recipes can range from super effective to total disaster.
The #1 reason homemade cleaners fail? They contain the wrong ingredients!
It's important to learn more about the ingredients you are using to make sure a new cleaner works as expected.

What is Cornstarch?
Cornstarch, corn flour and maize starch are all names for cornstarch, a natural starch made from the corn kernel. It is made by grinding, washing and drying the endosperm of corn until it reaches a fine, powdery state.
An All-Natural Substance
Because cornstarch is made from 100% corn it is all-natural and gluten-free product. (Please note: If you are opposed to GMO products you can purchase non-GMO cornstarch.)
History of Cornstarch

- Cornstarch began to be massed produced in 1840 when it was primarily used commercially for starching laundry.
- By 1892 cornstarch powder, as we know it today, was introduced to consumers.
