I have had great success using a mix of water (2 parts), peroxide (1 part) and dish/hand soap (just a small amount) to remove dark stains from light clothing, furniture, carpets, etc. Put it right on the stain and let it sit for several minutes, then blot and/or rub lightly with a towel. Rinse the shirt well afterward (or put it through the washer) to remove any residual peroxide.
