Without using some kind of soap, its never going to come up clean though? A wash down with a jetwash won't even get the flies off the front, let alone the film of road grime bonded to the surface. So it's full wash, complete dry with chammy, and then full polish / wax each time.
It needs doing again this weekend after it's 2000 miles to france and back last week. Not sure how I'll get all the flies off - need to buy a chamelon..
