When the temperature calls for below-freezing temperatures, do more than bundle up: detox. Lay a plastic tarp outside and put items that are next to impossible to launder -- like throw pillows, sofa cushions, children's plush toys and even comforters -- on top. Let these items sit there for as long as possible (about eight hours) to let the deep freeze clean them for you. Dust mites and odor that may have built up will literally be frozen to death. When you bring them back inside, they'll be fresher and cleaner.
