my red jersey bled and it colored the numbers and the stripes pink, so how to i turn it back to white again?

Answer 1

soak in Biz for a few hours, a bleach product that you can get at Walmart. I have soaked overnight for stubborn stains.

Answer 2

Repeated washing with color fast bleaches. You are basically out of luck. It will retain a pink tint pretty much forever. Check your lables and see if there were washing instructions. This will give you an idea of what happened and if worse comes to worse take it down to your local dry cleaner and ask his opinion. Luck
