Clean carpet stains! 1. Scrape up the liquid. 2. Sprinkle baking soda or cornstarch on stain to let absorb for 10 minutes and then vacuum. 3. Mix one tablespoon clear dishwashing liquid and one tablespoon white vinegar with two cups of warm water. 4. Using a white cloth (I strongly believe in microfiber washcloths), sponge the stain with the detergent/vinegar solution and blot until all the liquid is absorbed. 5. Sponge off with cold water and blot dry.
