If the lemon fails, bring out the heavy artillery. Soak the stain in straight white vinegar for 30 minutes. Then, sprinkle baking soda on top and watch it fizz like a science fair volcano gone rogue. This foam breaks the rust’s grip better than a toddler gripping a cookie.
Here’s the wild part: the fizzing reaction physically lifts the rust particles off the fabric. Rinse with cold water—never hot, or you’ll “cook” the stain in permanently. Repeat twice if necessary. Your clothes will smell like a deli counter, but a rust-free, clean deli counter.
