3. Sour milk
Got a rust stain on colored garments or shoes? Sour milk will become your new best ally. The bacteria present in sour milk help break down rust particles. Fill a bucket or basin with sour milk and submerge the stained item. Leave it to soak overnight, then rinse thoroughly and launder as usual. Once you remove the clothing or shoe from the wash, the stain should be almost entirely gone.
