1+above comment. IMO this is perfectly normal, just part of having an aquarium. I've always referred to it as calcium. People recommend cleaning it with vinegar (of course not pouring it in the tank).
I used to clean it with pledge (the dust remover) and had great results (once again, not in the tank). Not sure why it works.
