Can anyone help?? In our desperate rush to get off an overcrowded site, we put our awning away in the rain and promptly forgot about it when we got home. Have used it this weekend and it has areas of black "mould". Does anyone know how I can clean this off without damaging the awning, or of a company that cleans awnings? My husband is refusing to use the awning when we go to Cornwall in a couple of weeks until its clean so any advice would be greatly appreciated (I've got 3 kids and NEED my awning!)!. Thanks
