white lines on side of rv
there are white lines on the side of our rv. They will not come off when I washed it. I tried rv wash. Barkeepers friend. non-scratch comet with bleach. plain old bleach. Nothing gets them off. ...

we have a rubber roof. The lines are vertical. They are on top of studs/framework. It is like the sides of rv stayed clean there, but got dirty everywhere else.
