When it comes to the outside windows though, it's straight to the Soft Scrub. Doesn't scratch the glass (though be careful around the edges because it will scratch clear-coat) and does wonders on old car-wash pseudo-wax, accumulated Rain-X from the orange wiper fluid, bugs, tar balls, and most any other thing that can accost exterior glass here in New England. Takes a lot of rinsing, though, preferably with a hose.
Oh, and even though Glass Plus and Invisible Glass both come as pop-up pre-moistened wipes I've never had one bit of success with either, leaving more smears and streaks than when I started. If you're going to have to dry the glass with paper towels anyway, why not just go straight to the spray can/spray bottle? Save the pop-up stuff for Armor-All and the dashboard or other plastic interior bits.
EDIT: When it has to be absolutely positively 100% clean with no streaks/smears, look no further than these:http://www.amazon.com/Gerber-Birdseye-C ... B007VBYVVA
