Remove set coffee stains from fabric by blotting with undiluted white vinegar before washing as normal. Check the garment for complete removal before drying, which can further set the stain. If necessary, soak the garment in a solution of oxygen bleach, and launder again using detergent and more oxygen bleach.
- Blot with vinegar
Use a clean towel saturated with undiluted vinegar to blot the coffee stain. Allow the wet stain to soak a few minutes before washing.
- Wash the garment
Place the item in the washing machine and wash as usual. Remove the item from the machine, and check for complete stain removal. Do not dry the garment if the stain remains.
- Soak in oxygen bleach
Mix the oxygen bleach with water according to the package directions for a presoak. Make sure the powder dissolves completely. Test the solution on the garment in an inconspicuous spot, then saturate the stain with the solution, and rub it into the stain. Wait for 10 minutes before washing.
- Launder the garment
Wash the garment a second time, while using your normal laundry detergent and adding the amount of oxygen bleach indicated in the package directions to the load. Check for complete removal of the coffee stain and dry the fabric as normal.
