Yellow stains on white clothes can be a frustrating problem, but there are a few simple steps you can take to remove them. First, try to identify the source of the stain. If it’s from food or drink, you can try to remove it with a stain remover or by soaking the garment in a solution of water and vinegar. If the stain is from sweat or body oils, you can try to remove it with a solution of water and baking soda.
Once you’ve identified the source of the stain, you can start to treat it. If the stain is fresh, you can try to remove it by blotting it with a clean cloth. If the stain is older, you may need to soak the garment in a solution of water and vinegar or baking soda for several hours before blotting it.
