Heavy woolen rugs are a doozy to clean, especially if they're the size of a blanket or larger. Beating the dirt and grime out of a carpet is no fun, neither is using petroleum-based chemical cleaners that may strip the fabric's oil content or result in discoloration.
Winter offers a cleaning solution that is zero-cost and requires little effort on your part: Snow. Best done at a temperature of 25°F or colder, and on new or powdered snow (the finer the flakes, the more thorough the cleaning), this method works because below-freezing temperatures harden and break up bits of grease that have accumulated on the fibers.
Tip: Set the rug outdoors for half and hour, before spreading it flat on the snow, to prevent the snow from melting on contact and soaking into the fibers. Well, not unless you want a rug-sicle. ::Mother Earth News
