Got a stubborn spot? Time to get aggressive—but in a gentle way. Mix equal parts white vinegar and water. Soak a clean cloth in it, then dab the stain. Don’t rub, or you’ll mash the rust deeper into the fibers. Dab like you’re petting a nervous cat.
Now, make a paste of salt and vinegar. Spread it on the stain. Let it sit for 30 minutes—long enough to watch a sitcom episode and get distracted. Rinse with cold water. If the stain’s still there, repeat. Persistence wins.
Fun fact: Vinegar is actually a weak acid. But combined with salt, it creates a redox reaction that lifts iron particles. You’re basically performing electrochemistry on a T-shirt. You’re a mad scientist now.
