Removing soap scum
To the real estate editor: The fastest and easiest way to remove built-up soap scum from shower tile is to use a razor-blade paint scraper (the kind you use to remove spattered paint from windows).
If the grout needs a litte extra cleaning, a few rubs with a 3-M Scotch Brite non-metallic cleaning pad will probably take care of it nicely. Mrs. Robert Hobbs Torrance, Calif.
