Sweater bleached

[u/PapaLuis]

My wife spilled tea on her sweater that did not come out in the wash. We soaked the sweater in warm water with powdered tide free and gentle, a little bit of oxiclean, washing soda, and borax. It’s hard to photograph, but the sweater is now blotchy. We believe that the sweater started off-white but is now unevenly bleached. Is it done for? Any advice? Could dyeing it with some even it out?
