how do I get my #$%@##$%^% windows clean?

Thanks for all the replies.My problem now is I don't know which one to try.:-D I will try the simple ones first I guess and see how it goes.Ordered a can/tub whatever of cerrium oxide,so I will be trying that first.I heard that newspaper was a good cleaner,someone even said to use a paste made out of ashes and a little water,it really stinks.8)
