Test for colorfastness by wetting the inner seam of a garment with cold water and allowing it to sit for a few minutes; press firmly onto the seam with a white cloth. If no color bleeds onto the cloth, then the garment is colorfast and you can attempt to remove the rust stains. If the garment is not colorfast, then it will need to be taken to a commercial dry cleaner for professional treatment.
Sprinkle the rust stain with enough salt to barely cover it, and saturate the stain with lemon juice.
Allow the garment to completely dry in a sunny area.
Rinse the article of clothing well and launder as usual.
Things You Will Need
- White cloth
- Lemon juice
- If the rust stains remain after the lemon juice treatment, cover the stains with powdered cream of tartar and soak the garment in hot water for approximately five minutes.
- If your washing machine is the source of rust stains, use an alternate washing machine or launder by hand.
