So I've used flipper max and other scrappers. None work to remove it. They will remove the film of algea and what not. But not these hazy areas that seem a little more caked on.
You can only notice it when your below tank level looking up toward water surface, but glass has a haze in spots, clearly something.
What do you use? Straight up razor blade, magic eraser, what? It's annoying, any tricks?
