I'll back Orient on that now, because that's what I do now over the newspaper, but I couldn't remember the product name.
That stuff rules!

 

I tried newspaper this morning and it seemed to do a really good job (who would have thought?).

I will reserve final judgement until I can get it out in the sun for a full critique. I also plan on trying the microfiber towel and the aerosol window cleaners too.

Thanks for all the great suggestions!
