Good idea, Jan – about the orientation.
But my thinking was that grime might build up, rather than dust; there might be
a film of muck on the surface, much like you’d find on the inside of your car’s
windscreen/shield. I realise that it doesn’t get as much exposure as your car’s
glass, of course . . .
