best glass cleaner?

after i wash i use Autoglym glass polish but this isn't getting off the water marks.

i need something better, more abrasive. there's also marks from the wipers which need to be removed.

any pointers?

Cant beat clearkote vanilla moose glaze for cleaning windows. Supposed to be for paint but can also be used on glass :wink:

I have some of that..i'll give the stuff a go on glass.

I use AG Glass Polish and can't fault it.
