You can get coffee stains out of clothing or other fabric with vinegar, dish soap and warm water.
To remove coffee stains from clothing or other fabrics just mix two cups of warm water with one tablespoon of dish soap, and one tablespoon of white vinegar.
Next use a clean, white cloth to blot the coffee stain with the mixture.
(Make sure the rag is clean and fresh, like a paper towel, to avoid color transference.)
Repeat blotting until the coffee stain is gone.
Dried coffee stains on clothing often require a soak in a cleaning solution to completely lift out the spot.
A solution of distilled white vinegar, liquid detergent, and water can effectively loosen coffee stains after a few minutes.
