How do these come off? Are they pressed in somehow? I'd like to take them off to polish the crank and then reinstall them.

They don’t come off.
This Acera crankset has the chainrings riveted so they cannot be disassembled.
you don’t- these are riveted together and when one wears out, the whole assembly gets replaced.
Alas they are riveted on. Removal would be permanent.
Bummer, thanks all.
Nope. Mechanic meet rivet 🙁
Unfortunately, you don’t! Those are factory rivets. Pipe cleaners work fairly well to get into hard-to-reach places like that.
They look permanent.

They are riveted. You can remove once but can’t use it anymore aka break it 🫠💀
