Two days ago I saw that one of my favourite shirts has mold stains. So far I’ve soaked it in 1:1 water and vinegar, dilute colorsafe bleach, and detergent separately for a few hours each. That might’ve killed the mold but the stains aren’t coming off. I rubbed powdered detergent on the shirt and left it in the sun for a few hours then scrubbed it with a toothbrush but the stains are still there.

Do you guys know of any good ways to remove mold stains?
