You've just installed new light-colored wall-to-wall carpeting. Then you or a guest spills red wine on this cherished new purchase. Don't panic. Instead, grab a box of table salt and club soda. If you don't have club soda, water will do. Sprinkle salt on the stain (enough so that it starts soaking up the red wine). When the salt turns red, vacuum it. Then apply club soda or water, and blot with paper towels or a cloth rag. Follow up with more salt, and keep repeating the process until the salt goes from pink to white. Then give a final rinse and blot the spot to remove any leftover salt. It could take several days, but the stain eventually will fade away.
