If the 'Glass' is acrylic it can be polished with a metal polish like
Brasso. If it is Glass then doing a Google search came up with a couple of
possibles:

Good luck

Ahoy, I have a portlight that someone scratched up, perhaps by using a
wire wheel to clean the bronze. The glass is all scratched up. Is
there some kind of compound that would buff it out?
Thanks.
