To remove coffee stains from colored clothes, take a white, wet paper towel and gently press it on the stain multiple times to remove as much as possible. Get 1/3 of a cup of white vinegar and mix it with 2/3 of a cup of warm water. Soak another paper towel in this solution and start gently pressing it on the stain until the stain is gone.
Try to remove the coffee stain as soon as possible, because it's more difficult to remove once it sets. When applying a paper towel to the stain, use a gentle, up and down pressing motion. Don't rub the stain, because this spreads the stain. Use only white paper towels, as colored paper towels can discolor the clothing.
If you don't have vinegar available, several household items remove coffee stains, including club soda, baking soda and egg yolk. A commercial stain remover also does the job, but you must wash the clothing immediately after using it.
If possible, read the label on the clothing before trying to remove the stain, as the correct method varies for washable and non-washable fabrics. With non-washable fabrics, use only warm water to remove the stain. If that doesn't work, you must have the clothing professionally cleaned.
