Have several small brown stains on my roof, about the size of a 20p piece, which are proving difficult to remove with soap and water. They look like dirty water stains from a heating tank or similar. Not really sure where my Zed was stored previous to my buying her. I would prefer not to use the garage jet wash route so any suggestions would be a start. What does everyone use to clean and seal the roof?
