How do you remove gas smell from rubber mat?

To remove a gas smell from a rubber mat, first, wash the mat with a mixture of warm water and mild dish soap. Rinse thoroughly and dry it in a well-ventilated area. For persistent odors, sprinkle baking soda over the mat, let it sit for several hours, and then vacuum it up. If the smell lingers, consider using a mixture of vinegar and water to wipe down the surface, as vinegar can help neutralize odors.
