castrol super clean. the purple bottle in wal mart automotive section might work.

When you say windows, do you mean on a model car or are you referring to actual glass?

Depending on what type of window would determine your course of action.

You may be SOL on this one. Urathanes can be tough to remove. I'd give 99% isopropyl alcohol a try. But anything stronger than that and you're likely to damage the clear parts. Personally, I never would have tried thinner on clear plastic.

What are you building...?

I might suggest just getting a new "glass" part. it will be the easiest route.

Soak the piece overnight in DOT 3 brake fluid.

As you rinse it with water in the morning, use a stiff brush to remove the polyurethane paint. (Wear gloves. If it removes paint, just think what it does to skin!) I don't know what BF that will do to that particular plastic, so be ready to replace the piece if it destroys that one. Brake fluid costs about $1.50 and you can find it at any auto parts store. But keep it away from all painted surfaces!
