How to Remove Old Coffee Stains From Carpet

Coffee contains tannin, giving it a pleasing rich brown color. Unfortunately, that pleasing color stains fabrics and other items easily, leaving dark patches and spots. The best way to remove coffee stains from carpet is to blot them up as soon as a spill happens, followed by a rinse with clean water. That is not always possible, however, especially if you're not aware of the spill when it happens. Even though it's best to clean fresh spills, all is not lost if an old coffee stain is found.
