Hello adiaw83
I asked a friend in the Rolls-Royce Owners Club who lives in Washington D.C. about your problem, here is his first response.
Ohh this person has parked the car someplace different than normal.
I had this happen once before...because of the trees I was parked near.
But once you get that problem...it is very hard to get rid of.
He's going to have to spray down the whole interior with a mildew disinfectant, and keep a couple boxes of baking soda open in the car, when parked for a while, and if possible keep the windows open a crack.
There is a good glass shop called Cherrydale Auto Glass on Lee Highway here outside DC.
So I will look them up and forward to you.
here is his second response.
Yes: Have him call: Best Auto Glass, they do mobile installations, and the
other place does not. But he will have to have a new gasket, if that model takes it...then there is the issue of the rust around the windshield.
The number is 703-339-2266 As for M.B. repair places there are quite a number of them here in D.C. Some of them come recommended by the MB club, and others not.
Let me know....if you need their names.
Note: post if you need their names.
I hope this helps you enjoy your car.
Happy motoring.
