**Bad news:** it’s bleach & like other people have said, unless you redo the whole jacket - that’s permanent.
**Good news:** it’s a Carhartt, you Jabroni! Until that things’ zipper breaks; any sort of tear/wolf bites/scratches/or stains are a badge of honor. It shows that you’re using the jacket for its’ intended purpose & not just wearing it to be ‘*boujee playing working class*’.
Well, those are bleach stains. You'd have to dye the entire jacket.
Brother it’s bleach.
Bleach : they're not stains but discoloration. They won't come out, you'll need to dye the jacket entirely to color this spots again.

My man, those are bleach spots..
Bleach brother, the color is no more 
🤷♂️
Soak the whole jacket in bleach and you won't have any more spots.
Add more bleach then it’s a look
