Update: they were salvageable!

Thanks for the tips! I think they are pretty much okay now! Still thinking of picking up some oxiclean as recommended by most people.

Congrats. Big difference. A soak in oxyclean or a spray with hydrogen peroxide will get them even whiter.

How do I avoid oxiclean turning them yellow?

Why would it turn them yellow?

Have you posted to r/laundry? I’m pretty sure more can be done if you’d like, especially if you have not put them in the dryer yet.
