Since Rug Gripper is made using a water-based adhesive, it cannot be washed. You can, however, remove the strips from the back of the rug or mat to wash it, then replace them after you rug or mat is dry. As long as the strips remain clean and dry, they can be reused.
If your Rug Gripper strips do get wet, all is not lost. Although the product will not be as strong as it was originally, once Rug Gripper has dried, it can be used again.
