Clean greasy messes
Greasy pans? Splattered stove tops? Messy counters? If your kitchen has been the victim of some sloppy sauteing, try using lemon halves before bringing out possibly toxic chemical cleaners. Sprinkle some salt (for abrasion) on a juiced lemon half and rub on the greasy areas, wipe up with a towel. (Be careful using lemon on marble counter tops, or any other surface which may be sensitive to acid).
