Cleaning a white north face jacket

[Pearlgirl13]

Hello all,
im Wondering if anyone knows how I can get this north face gilet cleaned… I’ve washed it/ tries oxyclean spray for colors / baking soda… nothing seems to work! Any advice would be appreciated… thanks!

Anyone?

Any idea what the stain is?
My go to would be citric acid and sunshine if you've tried all the usual stain removers.
Dissolve citric acid in boiling water. Once cooled put it in a spray bottle and spray the marks. Then leave to dry in bright sunshine, either outside or on at a sunny window. It might take a few attempts but it usually works. My dd recently spilled bright red oil paint on her pale grey trousers and this method worked when everything else had failed. I had to do it a few times though and the stains just gradually faded away each time. I buy my citric acid at home bargains or b&q, it quite cheap.
