How to Remove a Coffee Stain from Carpet

1. Blot up the coffee with paper towels.
Blot up as much of the coffee as possible as soon as possible. Remember: blot, don't rub.
2. Spray some water on the stain. You can also dab some water on the stain with a sponge.
3. Prepare the following cleaning solution: ¼ teaspoon mild, non-bleaching detergent or carpet shampoo to 1 liter of warm water. Stir the solution in a bowl to mix thoroughly.
*Before you apply any cleaner--including the one in these directions--to your carpet, test the cleaner in a small patch where no one will see it. Wait a few minutes. If the cleaner discolors or otherwise adversely affects the carpet, remove it immediately with cold water and a sponge.
4. Moisten a clean, white cloth liberally with the cleaning solution, and simply lay the cloth over the stain.
5. Lift the cloth off of the carpet, and spray warm water onto the stain. Alternatively, you may moisten a clean sponge with warm water and gently dab the stain.
6. Blot the stain with a clean dishtowel or sturdy paper towels. Blot, don't rub.
7. Let the carpet dry.
