Fighting grime: The Tang-y toilet
You may not want to put it in your body, but it turns out that Tang is a great toilet-bowl cleaner—its sugary combination of citric acid and gritty powder works well when combating rust stains. Simply sprinkle the orange delight into your toilet bowl and let sit; after an hour or so, a normal amount of scrubbing should remove the rust. And Tang is non-toxic to boot! [Insert joke about how the Space Shuttle must have extra-clean toilets here.]
