I have a 40' Newmar and after horrendous rain/hailstorm that caused roof damage, I have water stains throughout!!! I have read previous posts about the removal of water stains on fabric ceiling liners. Tried them all...oxyclean, Spot Shot, bleach&water, InstaGone, Quick10, everything. They are still there. I am sick over it. Does anyone have any other suggestions (could there possibly even be any?!?!) of getting rid of them. Will I need to redo headliner? If so how would I go about that? Any and all suggestions will be greatly appreciated.
