Secret Stuff® Hygienic is the world’s first hygienic chalk! Made with an 80% ethyl alcohol base, this high performance, pure magnesium carbonate formula is engineered to provide unparalleled grip and reduce the spread of germs.

With less dust and mess and a formula that’s shown to kill germs, Secret Stuff Hygienic takes “clean chalk” to the next level.

In 2020, 10% of proceeds of all Secret Stuff Hygienic sales were donated to organizations working to increase diversity in sports.
