  Dogs track in dirt, kids spill juice and snacks and even a simple outdoor chore can leave stains and dirt on carpet. Sometimes a simple vacuum cleaning doesn't do justice to the deep down dirt residing within carpet fibers. Choose from a few different cleaning methods to remove dirt and lift stains.
  
  

Remove Stains

• For just-spilled stains, blot dry with a paper or cloth towel. Avoid rubbing the carpet as the stain can mix with the fibers, making it more difficult to remove. For water-soluble stains such as soda, milk, food dye or wet paint, use a solution made of a 1/4 tsp. of white vinegar and 32 oz. of water.
  
  For dark stains like blood, wine or chocolate, mix 1 tbsp. of ammonia with 1 cup of water. Be careful with wool carpet and wool blends because this might bleach the fibers. Check with a manufacturer before applying, says thisoldhouse.com.
  
  

Vacuum

• Get the deep down dirt thorough vacuum cleanings. Go over the carpet in several different directions to pick up the most dirt. Dust that gathers on light-colored carpet can make it look gray, so move furniture around and suck up dirt in hard-to-reach areas with a hose and a nozzle. Get a high-quality vacuum to get the most suction, and empty the vacuum bag regularly, says carpet-cleaning-tips.com.
  
  

Shampoo

• Rent a steam cleaner or shampoo machine, or purchase one from a home supply store. A cleaning solution combined with warm water can lift hard-to-remove stains and attack soil embedded into carpet fibers. Follow instructions for wet machines explicitly because over-soaking a carpet can produce mold and mildew. To dry the carpet faster, use a fan or dehumidifier over the cleaned area, says "Better Homes and Gardens."
  
  

Professional Care

• Hire a professional to regularly maintain carpets. Investing in an occasional professional cleaning will help make the daily upkeep easier. Get informed about cost and cleaning procedures before the cleaning begins. Find out what cleaning solutions they use, and make sure it is compatible with your carpet. The Carpet and Rug Institute recommends getting a professional deep cleaning at least once every 12 to 18 months.
