Summary: Get your RV foam looking clean and smelling fresh with a deep clean. All you need is some vinegar, water baking soda, and a spray can. Apply baking soda to all sides of the foam and let it dry. Then dust off the baking soda and spray an equal mixture of water and vinegar. When the foam is completely dry, insert them into the covers.
It is almost certain that every RV will have at least one or two cushions, mattresses, or seats that use foam.
