How do I get car wax off my windshield?

Dear Tom and Ray:

I get my car washed at the gas station car wash a couple of times a month and
always get the super duper package which includes spray-on wax. Now, I know that
I am supposed to wash and wax my car in the driveway every Saturday afternoon --
and if I did, I wouldn't wax the windshield. But since I have better things to
do with my time (like watching the tube and scratching my butt), I use the gas
station car wash that gets wax on my windshield. So how do I get the wax off my
windshield? And as you can probably tell from my attitude, I'm looking for the
quick and easy solution. -- Randy

TOM: Well, it doesn't get much quicker or easier than this, Randy. You don't
have to do anything.

RAY: Right. The car wash folks claim that the wax they use doesn't stick to
glass. It sticks to the car, they say, but not to the windows.

TOM: Perhaps it's some kind of special wax that doesn't adhere to glass
surfaces. Or perhaps they use some additive in the wax that keeps it from
bonding to glass.

RAY: Or, perhaps they don't apply any wax at all! How would we know? Maybe that
extra two bucks you pay covers the electrical bill for the sign that says
"Applying Hot Wax Now!"

TOM: Actually, I'm sure most car washes apply some sort of wax product when you
pay for it. But since they use about eight cents worth of wax concentrate per
car, I can't imagine that it's as good or as long-lasting as a good-quality
paste wax (but you folks in the car wash industry are welcome to write and
convince me otherwise).

RAY: But you don't really care, do you, Randy? All you want to know is how to
keep wax off your windshield. And either way -- -whether they apply special non-
glass-adhering wax, or no wax at all -- -you're all set!

TOM: So now that we've eased your worried mind, Randy, we hope you can relax and
enjoy the important hobbies you mention in your letter.
