I just washed these clothes in my building's laundry machines. These shirts came out with these stains. They did not have them before. One of them is a brand new shirt- never worn.

The first pictured shirt is 70% cotton 30% poleyester. The second- the brand new one- is a blend of 35% polyester, 31% viscose, 30% microfiber, and 4% spandex.

Someone in the r/laundry subreddit said it was oil, but they didn't recommend any removal techniques, so I thought I'd try my luck here. They both went through the dryer before I noticed them. I tried a Tide Stick, which offered small but minimal improvement. Is there anything I can do???
