The best defense for removing stains from carpets is to clean them immediately after the stain occurs. Unfortunately, you may not always be able to attack the stain right away. Dried-in stains can seem quite stubborn. Luckily, there is a general removal method for dried carpet stains that works for most stain types and will not damage your carpet.
Things You'll Need
Towels or rags
Carpet spot remover
Plastic knife or dull butter knife
Scrape off any dried residue on the stain, using a plastic knife or a dull butter knife. Vacuum any residue you scratch away.
Soak the stain with club soda.
Cover the stained area with clean white or light-colored rags or towels.
Stand on top of the rags or towels for approximately one minute.
Blot the stain with a dry, light-colored towel.
Repeat the process of pouring the club soda, covering with towels, adding the weight of your body and blotting with more rags or towels until you don't see any more stain transferring to the towels or rags.
Apply a carpet spot stain remover and blot the area dry with a towel to remove any lingering stain.
Read the label on the carpet spot remover before using it so you know it's safe for your carpet.
