I have scrubbed until it's a smooth surface that feels very similar to the original glass top but the surface is so dark it's nearly black. I can slightly see the original pattern in the dark areas which makes me think it might be salvageable.
If anyone has any ideas I'd be happy to try them.
What I've tried:
- Razor blade
- Aluminum foil ball
- Barkeepers Friend
- Baking Soda with (Peroxide, or water, or vinegar)
- Sulfuric Acid [Strong drain cleaner] (but I did not scrub)
