I have recently acquired some unfortunate escalator grease (I think) stains on a favorite pair of khaki-colored pants. Said stains are so far impervious to my best efforts at removal with detergent, a Tide stain stick, and Oxyclean. I'm out of ideas. Help? [more inside]

Why is it harder to run/walk up a stopped escalator than a moving one? Surely the step size is the same and your relative speed is the same?
