Stains On Tank

[Quentin]

During a water change some water splashed over the acrylic and dropped down the front of the tank. Regrettably I didn’t have any towels around and left it there and forgot about it. It has now turned into a blank white line down the front that makes it difficult to look at the tank. Does anyone have any idea how to get it off? I’ve tried windex and glass cleaner with no success.

CLR or vinegar would work.
