Blue Stains on Sweatshirt (supposedly caused by whitening detergent)
After running sweatshirt through the washing machine with concentrated whitening detergent by accident, these blue stains appeared on the white band. I have tried running it again through the washing machine and using baking soda + vinegar. Is there anything that anybody can recommend giving a try? Any thoughts will help.
