wiper blades were replaced but although much better than the old ones ,still leaves a smear after each wipe but disappears after a few seconds.should the glass be cleaned with metho or something similar for a clean wipe.

Glass cleaner?

Or normal polish and it shouldn't leave any marks.

Could always use some Rainox on it? That stuff is great!

Clay bar wind screen. Throw away after use.

Have a look afterward at the bar though ... You'll be amazed.
