Solution: For heavier stains on marble, take three or four cakes of Ivory soap, cut them up and dissolve in hot water until you have a "slurp."
Paint this on the marble and let it sit for five days or so. If the gunk starts to dry during that time, consider slopping some more on -- or wetting it down. At the end of the period, hose and wash it all off. Presto! The marble is as good as new! -- Ken Holmes, OHW publisher, and in OHW story: /stories/Detailed/221.shtml
