Assuming you would like tips on how to keep your door mat dry: 1. If your door mat is made of absorbent materials, make sure to hang it up or lean it against a wall after using it so that both sides can dry evenly. 2. If you have a non-absorbent door mat, such as one made of rubber, plastic, or metal, you can hose it down and let it air dry outside. 3. You can also vacuum your door mat to remove any dirt, dust, or debris.
