When we were kids, not only did we love drinking it, but we used to use Coke to scrub the rust off our bike tires!  Over the years I've heard of other home-type remedies that involved Coke, like Cleaning burnt charrings from baking sheets or lifting oil/grease spots from sidewalks or garages.  But here's a couple more that I have just stumbled on and will soon try:

Defrost a frozen windshield (I prefer to wait to try that one) ... Get rid of an unwanted ant hill ... Cleaning a stained toilet bowl ... and the big one, improve your compost pile !!

Got any others ??
