We have an acrylic mirror in our bathroom which is stuck on the wall with sticky pads - we bought and installed it when we moved in as there wasn't one (bare wall above the sink!)
Problem is, I tried to clean it using tissues and now an area of the mirror is lightly scratched and cloudy. Stupid me! 
I found some acrylic polishing products on Amazon but apparently you are supposed to lightly sand it using fine grade wet and dry sandpaper before applying the polish. I'm confused, as surely sandpaper will scratch it more???
Does anyone have any tips?
