Is there wax for windshield?
My 2004 Chev Truck did this; it was ambient crud from undercoating spray.

By crikey this topic takes me back.Rain-X is the 3-5-1 code of the W210. I remember all the regular complaints about wipers and smearing! (even more threads than our 3-5-1 issues) Some members swore by Rain-X, others hated it.
Going back to this problem. My wife complained of our wipers making an awful noise when working at their fastest speed!
I told her to put the wipers on a slower speed, but that comment did not go down very well. Has anyone else experienced excessive noise from their wipers when working at the fastest speed during heavy rain.
Before anyone comments,. we do not have 'heavy' rain here is sunny Torquay, 'she that must be obeyed' was on a trip to Cornwall.

Dont out MBs use a proprietary refill available only at the dealer?
I've been using Rain-X, and I've been a long time proponent of them ever since I started putting it on my cars years ago. While it did help visibility and reduced the need to use the wipers greatly, it still did not reduce the noise.
I totally forgot to mention this while my car is in service right now.
