The process for removing coffee stains depends on the material that has been stained. For example, synthetic fabrics require a pre-soak in a washing solution, before being rinsed and washed in a washing machine, while burlap, silk and wool require treatment with white vinegar and absorbent pads.
To remove stains from burlap, silk, and wool, blot any excess spillage, and sponge the stain with water. Use a wet spotter and a few drops of white vinegar, and cover the stain with an absorbent pad that has also been dampened with the spotter. This pad should remain in place until it is no longer removing any of the stain. Flush the material with water, and repeat the process until the stain is gone. If the stain still remains, use rubbing alcohol instead of spotter and vinegar in the same process.
To remove stains from carpets or foam rubber, blot up as much as possible, and apply either Stain-X, Spot Shot, or Afta Carper Stain Remover. Flush the area with a mixture of 1 quart warm water, 1/2 teaspoon liquid laundry detergent and 1 tablespoon of white vinegar. Blot the area with a clean pad, and rinse it with water. If a stain still remains, use an enzyme pre-soak before flushing the area with water and blotting until the stain is removed. Finally, sponge the spot with water, and use a clean pad to absorb any extra liquid before allowing the area to try.
