Coffee stains can leave a carpet “dirty” or “brown” if not treated properly. It can cause the carpet to have a yellowish-brown tone that is quite noticeable. After blotting the dampness and coffee from the carpet you will want to follow these simple steps for removing coffee stains from your carpet:

Try the mixture of vinegar, water, and Dawn detergent first with the spritzer method, rinse, and repeat.
There are several products that are sold in such stores as Wal-Mart, Target, Walgreen’s, and other retail chains that sell specific cleaners for this type of carpet stain.

There are certain types of carpets such as Polypropylene that will respond safely to a carpet stain treatment of water and bleach. You can create a mixture of 1/4 cup of bleach to 1 ¼ cups of water in a spray bottle. Spray the stained area, soaking it thoroughly, blot, rinse with warm water, and repeat until the carpet stain disappears.
