Fab Tip: Vodka-Infused Cleanliness I recently got a tour of the backstage at the San Francisco Opera. Fab-u-lous. The drama, the behind-the-scenes action, the velvet, lace, beading. Oodles of hats and costume jewelry — I could have played dress-up for hours, it was a real treat. Along the way I picked up a stain-solution tip I'd never heard, or imagined, before.
