How to Get an Old Rust Stain Out of Fabric

Moisture left to sit on metal will oxidize and create rust. When the rusty object comes in contact with fabric, the rust will transfer onto the item and leave a difficult to remove stain. You typically cannot remove rust stains from fabric with a simple washing. Furthermore, the longer the rust is allowed to sit on the fabric, the more difficult removing it becomes. Fortunately, you can still remove the rust stain with the help of a few common household items.
