Figured I would post an update for anyone who has this problem in the future. I used the website above ( thanks f5). There was a suggestion there to wash with detergent and 1/2 cup baking soda and then add 1/2 cup of vinegar during rinse. Then air dry, I laid them out in the sun. It worked.
I also left a damprid package in the camper as another poster suggested.
