No salting of the roads or grit where I am (except the rare snowfall in which case the Z4 doesn't see outside anyway) so it doesn't get too mucky. But being black, it is the world's most effective dust magnet, so I will usually wash it at least every 2 weeks; snowfoam and/or bucket and 'noodle glove', chamois dry![]()
