a77impala beat me to it. Toothpaste is one of those lifehacks for cloudy plastics. It works well for cleaning up older headlights on a car, etc. I wouldn't be surprised to see it clear up those badges. Plus it would be an easy step, so even if it doesn't work, it's not like you lost much out of it.
