Well, that's 2/3.

The "after" looks like it'll be Monday at least. Needs, apparently, to thoroughly dry before stage ll. Being of a slightly suspicious nature I have a photo of his van Reg No. (Just in case)
May be a LOT, but well spent, if he doesn't reappear coz I'd never have got them THAT clean.
