Never use chlorine bleach on a rust stain. It will literally feed the rust and make the stain permanent. That’s like trying to put out a fire with gasoline. You will cry. You will google "how to undo a mistake." Just don’t do it.
Also, always always check the stain before you toss the item in the dryer. Heat sets rust stains like concrete. You wash, you treat, you rinse, you inspect. If the stain is gone, then you dry. If it’s still there, repeat the lemon-salt dance. Patience is your secret weapon.
Remember that park bench from earlier? Yeah, I do too. I sat on one after a rainstorm and left with a perfect orange circle on my butt. I used lemon juice and a lot of patience. The stain left, but the memory of my own naivety remains. You’ll be fine. You’re not a bad person. You just need a little chemistry and a good attitude.
So next time you find a rust stain, don’t panic. Get a lemon, have a laugh, and give your clothes a second chance. They’ll thank you by not looking like you moonlight as a welding apprentice. You’ve got this.
