Windshield cleaner?

[alicefred]

I recently purchased a 1993 TBird. Everything is in good condition, except the windshield. There are many ugly sticker marks on windshield and fine scratched on the driver side. I searched online and found lots of windshield cleaners available in the market. I also found discount on cleaning products at http://www.dealrocker.com. Wondering if any of you have tried any windshield cleaner and have any success, please share what you used and where did you got it from?

Thanks in advance.
