Highly recommend Outdoorsy..basically uber for RVs. We had a GREAT experience and also was SO fun as family trip!!

Peroxide works wonders for me if the stain is newer, and hasn't soaked in for awhile. If the pee has set in you may have to treat it before using the peroxide. For a pre treatment you can mix water, white vinegar and dish soap in a spray bottle and pour it ALL over the area. Scrub it in good and then blot. Then you can cover with baking soda, and leave to dry.
