Removing rust or brown spots on inside trailor wings?
Inside the wings of our shamrock 21 ft camper there are dark brown spots.
They are not on the outside. I do not know if they are rust or some other thing, but I am wondering if anyone else has this issue and if anyone knows how to remove them. Either with a product I can buy or with a home remedy.
