Red dust

[Carbon Based]

Anyone else really suffering from sporadic deposits of red dust? I vaguely recollect that it is linked to weather patterns bringing sand from the Sahara up to the UK.

Could just as likely be a big building site just down the road.

I'm more interested in how you get rid of it without scratching the paint? Plenty of water to start, Two buckets, lambswool mitt and I still have the feeling I might as well be sandblasting the car.

Any suggestions?

Thanks for the tips.

And by coincidence, http://www.bbc.co.uk/news/uk-26844425 - will wait a few days before attempting anything.
