I got this shirt online used and didn't realize there were stains on it. I thought I could fix it myself with a paste of baking soda, soap and a splash of hydrogen peroxide. Now after rinsing it looks weirdly blotchy, not even in the places I applied the paste. Not sure if there's any hope for fixing it. Material is wool. I would be open to dying or bleaching as well if anyone has alternative ideas. Thanks!
