Ask the MB: Sunglasses Maintenance
A: Don't do anything rash — that bug's a feature! Tarnish is just nature's way of achieving artful dishevelement. While we don't necessarily welcome it on our soup spoons, we think a little looks great on a pair of Persols.
Now, if your silver hinges have turned black or are crusting up, that's another story. In that case, our glasses expert tells us that jeweler's rouge, applied via a cotton buffing wheel (which itself is attached to a grinding wheel), should do the trick. A good optician should offer this service.
