Cleaning clothes without water and walking on the moon both sound impossible, and yet seeing Buzz Aldrin's space suit at the dry cleaner's provides evidence of both. Defy skeptics with today's Groupon: for $15, you get $30 worth of dry cleaning at Emerald Cleaners.

At Emerald Cleaners, textile technicians meticulously cleanse and deodorize every type of fabric and garment. After spending the spring and summer stowed away in closets and vacuum-packed genie lamps, coats, sweaters, and scarves undergo thorough ablutions (approximately $26.95 for five garments). Clothing experts render men's or ladies' suits ($11.30) minty fresh for business meetings or swank soirees, and dresses shed grime and distracting Rorschach prints after a water-free scrub down. Freshly scented wardrobe benefits the individual, the family, and the sensitive olfactory organs of wire-hangers and bureau drawers.
