The mirror assembly is a little jewel, indicative of the quality of craftsmanship in even the smallest details of the M-B products of the era.
The first job I performed on my 230SL after I got it last winter was to remove, dismantle and clean the rear view mirror, as it was all "filmy" and nasty inside after 37 years. I just couldn't stand it! As it happened, all it needed was a good internal cleaning to restore a like new mirror appearance.
Some tips:
The whole mirror assembly, arm and all, is a break away design and can be removed from the windshield header by smartly pulling it back towards the rear of the car, away from the windshield glass.
The mirror case can be taken apart fairly easily by separating the perimeter frame that holds the clear glass from the case. There are four little tabs that go into slots, two on the bottom and two on the top of the case. You do not have to bend the tabs, just gently pry the outer perimeter frame free of the case with a fine blade. I put a paper towel between the blade and the case to prevent scratching the chrome. Pay attention to how the day/night toggle lever and its little spring clip are installed. They are small and can fall out and lose themselves easily! There is a rubber gasket that keeps this clear glass from rattling around and, in my case, the glass was well stuck to it, so I cleaned the clear glass "in place" in the frame.
The mirror glass itself is loose within the case and can be removed for cleaning. My recollection is that there is a small coil spring behind the mirror to keep it from rattling within the case. If the silvering is going it should be no problem to have a glass company make you a replacement mirror, using the old one as a pattern. Be sure that the replacement has exactly the same dimensions as the original because this will affect how the day/night movement works.
Reassembly is simple once you have seen how it came apart. Just be sure that the day/night toggle lever and the spring clip are positioned properly before snapping the perimeter frame back onto the case. Work the day/night toggle lever a few times to assure proper action of the internal mirror bafore snapping the whole assembly back into the windshield header. This is the hardest part of the whole exercise! I used a rubber mallet and a great deal of care.
