Now Craig , would I, :evil: . I have often thought about these item and then discarded the ideas, as my caravan and roof is spotless apart from the crud the pigeons in the barn where I store it, deposit their after dinner extras. So I use the black streak remover about once a month on the areas that are starting and around the hatch doors etc. Doesnt take long and works really well. But we tour a lot and when in storage the vannis under cover.
