Bringing wool sweaters and blazers to the dry cleaner isn't just an expensive way of maintaining and cleaning them, it can also be an unhealthy choice. Conventional dry cleaning uses a cocktail of chemicals, including the carcinogen often simply called "perc" -- perchloroethylene -- which cleans dirt and odor from clothes. But if you're bringing items to the dry cleaner to get out odors, try this instead: Spray a little vodka on your clothes. The vodka will disinfect and kill the odor-causing bacteria to bring back freshness. Just don't replace vodka with rubbing alcohol; it won't do the same thing, since rubbing alcohol has additives in it that make it much less effective.
