Phil,
I have what looks to be rusty stains on my driver's side mirror. It's obviously from the inner workings of the housing itself rusting and dripping out onto the mirror.
I tried using stone's invisible glass cleaner and simple green but it wouldn't come off. I have a terrible pic of it for you, but you can get the idea. I can get a better picture of it if you'd like. (Sorry for any neck injuries that occur as a result of my tilted picture.)
Any suggestions?
Thanks in advance!
