Stained fish tank glass degrease?

My fish tank has some pretty tough foggy/white stains on it. I used pickle juice, a bleach water mix, some degreaser, a razer and a glass aqua scrubber. No luck though. How do I bring out that nice clear glass look?

Don’t be mad at me for using the degreaser (i’m desparate), plus I used just a little and rinsed it well
