Need help cleaning haze on tank

[xmjxflipx]

I bought a used waterbox 135.4 great condition except there is this haze at the top of the glass.

I thought it was water spots or hard water stains. I used paper towels overnight with vinegar, I have used diluted muriatic acid. I can't remove this stuff. Does anyone know what it is and what can help me polish the hell out of this to make this clear and not hazy

Nice aquarium cleaning kit. Usually a flat metal one takes care of that.

Razor blade, drop of water or soap, nice even pressure on whole blade... And scrape it...

Only thing u should watch for is not to press ends of blade too hard, you will burry them and leave scratch.... Light pressure, sharp blade and correct angle is all u need
