Answer 1

That's the mirror material flaking off. Not much you can do about it except replace the mirror.

Fortunately, mirrors aren't that expensive - call a glass guy and they can make new ones to order.

Answer 2

First of all, don't freak out! That's just dirt and dust collecting =P

All you have to do is unmount the mirror and clean the back of it and the backboard!
