Keeping your Omnigrid® cutting mat clean can extend the life of the mat. To clean your mat, use a sticky lint roller after every project and roll it over the mat. This will pick up any bits of lint and fiber that can get pushed into the mat's surface. You can also wipe it using a clean tack cloth. For spills or soiled areas, you can use a mild dishwashing detergent and water to gently wipe the mat clean using a soft, nonabrasive cloth, just be sure to rinse it well and only use cool water to clean and rinse it. You don’t want to use any chemicals on the mat because these can damage the markings.
