Bleach kills mold on clothes, but it can also weaken and discolor the fabric, so I treat it as a targeted tool, not something I use casually. Over the years, whenever I’ve seen mold spots on washable, bleachable items, I’ve used a controlled bleach wash: I brush off loose spores outdoors, then wash the clothes with detergent in hot water and add the amount of bleach recommended on the label.
This usually removes the smell and most staining, but if the fabric is delicate, heavily infested, or non-bleachable, I either use safer mold-removal methods or discard the item, because no result is worth damaging your health or the garment.
