For glass you can get a polishing compound but it will only work on very mild scratches, basically if you can barely see it and you can't feel it with your fingernail you might be able to buff it out but the compounds will likely not be safe to use on the inside of a full tank. If you can feel the scratch there's not much you can do.

Cerium oxide is the compound used to polish glass. Plus a rotary buff with wool pad. And a lot of elbow grease. Compound is not reef safe!!!

If you can feel the scratch with your nails, then it's gonna be there forever.

+1 on that. Cerium oxide can only remove very small scratches and if you manage to remove the deeper one you're going to create a magnifying glass effect, very ugly.

It does take a lot of time and effort to remove even just a small scratch. I simply gave up the idea after a while. Most small scratches don't really show when the tank is full of water.
