Ladies and gents - please! Colas are fantastic for cleaning the terminals of your car battery, but they are not fit for human consumption.
I use Pepsi for this... works great.
In the Navy we used a kool-aid type drink served on the mess decks to clean floor drains and brass fixtures. It was lovingly called Bug-Juice. I never drank that stuff. I still drink the soda though. A cold Mountain Dew while coding is quite nice.
