One thing you may or may not know about me is that I'm a bit of a Coca-cola fan. I drink it zealously, well, maybe not like a zealot; I don't think they had Coke back then.
I don't just drink with Coca-cola; I cook with it. Some of my favorite recipes are barbecued pork, Coq au Coke, crab bisque with Sprite, and Bulgoki with Coke. It's quite a good mixer. Some day I hope to try salted peanuts mixed in with Coke.
I have the Coca-cola Cookbook (Classic Cooking with Coca-cola), and on page 187 it lists a miscellaneous use for Coke. Apparently, you can use Coca-cola to clean up your windshield. If you are driving in the rain and have a bunch of road film build-up, you can splash some Coke on the windshield and let the wipers spread it around. This is slightly different than using it to clean your engine, which I've never tried, though I did use it once to clean battery acid off the battery. It didn't work as well as I'd hoped. It was also a waste of a good Coca-cola. Another experiment was putting a nail in a Coke. I left a nail in a coke for 3 days and it didn't dissolve. Nope. It just became sticky, and wasted another perfectly good Coke. Stupid people, trying to badmouth Coca-cola. For shame.
