careful cleaning that off, get the snow foam on it before you start brushing it with anything! Where abouts do you live Scotland I guess?
Just off the north coast.
Orkney islands.
We had a fierce night of wind and rain last night-couple that with the ash that the rain was bringing down,and then evaporating off the cars with the wind and this it whats left.
Pretty much any vehicle not in a garage overnight has been left in this state.
Just rinsed it off with a standard garden hose,to get the worst off.Not going to bother giving it a clean yet, as there is still a lot of ash in the atmosphere.I can actually see it build on the windscreen as I drive along!
