Here are some tricks you can use to get coffee stains out of your clothes assuming that traditional stain remover is not able to remove your coffee stain.

Beat an egg yolk and scrub this into the coffee stain with a white cloth. Rinse thoroughly with water when done.

Create a solution of half water and half white vinegar. Dab this into the coffee stain with a white cloth and rinse throughly when done. Vinegar will stain or alter the color of some fabrics, so test this on an inconspicuous area first.
