I got a pretty good deal on a 55 gallon former saltwater tank. I've gotten most of it pretty clean, but there's still some stuff on the glass that I can't quite seem to get off. The best way I can describe it, is that it looks like little fingerprints on the inside of the glass. Any ideas on how to clean this stuff off? A razor blade, algae scrubber, and vinegar doesn't seem to help.
