Removing undiluted yellow bleach stains from a white polyester blend top can be challenging since bleach can cause permanent discoloration. However, you can try the following steps to minimize the appearance of the bleach stains:
Act quickly: The sooner you address the bleach stain, the better your chances of minimizing the damage. If you haven't already, immediately rinse the stained area with cold water to help dilute and remove any residual bleach.
Test a small area: Before attempting any stain removal method, test it on a small, inconspicuous area of the fabric to ensure it doesn't cause further damage or discoloration.
Ascorbic acid (vitamin C) treatment: Crush a few vitamin C tablets into a fine powder and mix them with water to form a paste. Apply the paste to the bleach-stained area and gently rub it into the fabric. Let it sit for about 30 minutes, then rinse thoroughly with cold water. Repeat the process if necessary. Ascorbic acid can help counteract the effects of bleach on certain fabrics, but its effectiveness may vary.
Fabric dye or fabric marker: If the bleach stain is persistent and cannot be removed, consider using a fabric dye or fabric marker specifically designed for polyester fabric. Choose a color that matches your top or opt for a tie-dye or ombre effect to cover the bleach stain. Follow the instructions provided with the dye or marker carefully.
Professional help: If the bleach stain remains and none of the above methods are successful, it may be best to consult a professional dry cleaner or textile expert. They might have specialized techniques or products to treat the stain or provide advice on how to restore the appearance of your top.
Prevention is key when dealing with bleach stains. Always take precautions when working with bleach and ensure proper dilution and application to avoid accidents and damage to your clothing.
