I'm assuming these are water spots. I've never sprayed anything on the mirror covers. Will white vinegar and distilled water be ok to use? Anything better out there? What should i use after to protect the plastic
Thanks.

 

Never been through a car wash?


You'll want to use a general purpose cleaner, or degreaser here, you'll need a soft brush, or something that will reach into the dimpled plastic, to clean all this out.
To protect, a good hybrid ceramic spray will work, i also like CarPro PERL for any plastic/rubber dressing, it doesn't wash off like 303 does.

 

That looks like some kind of dressing slung up on the mirrors. They do not look like water spots.
