I just use steel wool for stains.

steel wool can probably help polish the glass some. Since the steel is less hard than glass it cant really cut the surface of the glass.
In tumbling you use a compound like silicon carbide that is harder than glass to do cutting.
You might try going to an auto store and getting very fine emory or carbide wet-sand paper and try that.

Don't worry, I spray pesticides just a little less worse than this..
Some thick clothing, chem. resistant gloves, plastic bucket in the middle of a field, goggles..
I'll be a good boy, just going to run some tests..
