Have you ever thrown away an expensive bit of stemware because it's become irreparably cloudy?  After many years and many replaced wineglasses, a friend (who happens to be the president of the Napa-Sonoma chapter of Women for WineSense) casually offered a better solution.  It's an inexpensive, somewhat mysterious product that I'd never heard of, and it magically renders opaque glasses sparkling clear without scrubbing or soaking for hours.  I got so excited by how fast and easy it was to use that I cleaned all the glasses, from Reidel to jelly glasses, in our house.  Anyone care to guess what this stuff is called?
