paint strip off windows

I've done a search, could not find one. I've got no problem stripping paint off bodies but how about windows. Is one solution more gentle than other and won't fog clear plastic?

I Have Used Simple Green Brand Cleaner for Years,And Have Had No Problems With It.
It's Safe To Use On Clear Plastic,And It's Non-Toxic
You Can Also Try Castrol Super Clean But It Is Not Non-Toxic.

if its not that bad, and need only a small amount off you can use rubbing compound to take it off.

I had exact same problem not long ago.
Most people on here seem to disagree on what you can and can't use|!

Better safe than sorry - I just used rubbing compound and took my time!

Good luck!
