Secret Stuff® is an isopropyl alcohol-based liquid chalk. Rub a small amount on your hands, let dry, and a perfect layer of the highest purity magnesium carbonate magically appears—and lasts. With less dust and mess, it’s the perfect "clean" alternative to loose chalk.
Plus, Secret Stuff goes further than regular chalk—it also cleans your hands, getting rid of gunk and grime that can build up while you’re working up a sweat.
Secret Stuff® Hygienic is the world’s first hygienic chalk! Made with an 80% ethyl alcohol base, this patent-pending, high performance, pure magnesium carbonate formula is engineered to provide unparalleled grip and reduce the spread of germs.
