Quoted from vid1900:

I'm telling you, don't even waste your time with some "baking soda and vinegar" home solution.
Call your local glass guru vandalism removal guys, and for ~$25 a square foot they'll fix your backglass, your scratched up shower doors, your boat windshield......
When the local Petco gets "PUPPY MURDERER" scratched into their front glass, they don't send an employee out with a tube of toothpaste, they call a glass shop and an hour latter their glass looks like new again.
