FREE: UNICORN design sculpture etched into a glass looking square.(PEGASUS)

The listing, UNICORN design sculpture etched into a glass looking square.(PEGASUS) has ended.

This sculpture looks like glass of maybe even ice,but it's a thick piece of unbreakable plastic(I'm pretty sure it's plastic) it has a beautiful unicorn(pegasus) etched into it from the back which you view through the front. Very pretty. I've had this item for about twenty five years,at least!!!!
I must say though, it was dusty and i wanted to clean it before i took the pictures and i used the rough side of the kitchen sponge,not thinking, and it made it a little hazy to look through. The pictures were taken after i did that so as you can see it's still very beautiful and clear to see through. Now I'm wondering what i can use to polish plastic that will give it back that totally Crystal clear finish and not further cloud or scratch it. Any ideas are appreciated. Maybe the winner will have an idea or some knowledge on what to do. I have just found that if i lightly rub it with a very little endust it makes it look really pretty.
