• The Origin of Grit-O'Cobs

    The product line known as The Andersons Grit-O'Cobs was created in the mid-1950s when our product development team imagined new uses for this all-natural renewable resource. The result was Grit-O'Cobs. The corncob grit comes from the hard woody ring which has mild abrasive properties, while the pith and chaff have highly absorbent qualities. Today there are dozens of Grit-O'Cobs products working in hundreds of applications throughout the world!

  • Get the Job Done

    Great results are no surprise when you choose the original-- genuine Grit-O'Cobs® granules. No matter the application, you'll achieve professional results and outstanding value. Hard and abrasive, yet soft and absorbent; strong and powerful, yet gentle and biodegradable, the properties of Grit-O'Cobs seem impossible. But bottom line, Grit-O'Cobs works. Accept no substitutes.
