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?
Depending on what sort of shirt it is, could you considered sewing an interesting patch over the area? Take a sort of ‘visible mending’ approach? That way it just becomes one more memory associated with the shirt.
