The back just looks dirty, but damn, those headlight washers really streak up the hood and front fenders.  The psychedelic colors and swirls look like I drove through an oil storm.  The headlight washers in my Audi are only activated every third windshield washer activation, but even still, they make a mess.

When will headlight wipers make a comeback?  Too bad they never even worked on my old 9-3.
