No panic. For the really stubborn, old rust stains, you can bring in a commercial rust remover made specifically for fabrics. Look for products with oxalic acid (like Bar Keepers Friend, but test a hidden spot first!).
These are like the heavy artillery in your stain-fighting army. Just follow the package directions, and always rinse thoroughly. Your shirt will thank you for not giving up on it.

Never, ever use bleach on a rust stain. I know, I know—bleach is the usual go-to for white clothes. But bleach actually sets rust, making it permanent and darker. It’s like pouring gasoline on a campfire.
Instead, stick to acids and gentle abrasives. You are smarter than bleach, and your clothes know it.
