Rust stains are sometimes hard to remove on coloured clothing with a regular washing powder. Once you've noticed a rust stain on any type of coloured fabric, treat the stain immediately before the rust hardens, permanently damaging garments. Investing in a good stain remover can eliminate rust, but homemade rust stain removal solutions can be just as effective.
Add coloured clothing to the washer. Place enough clothing into the washer so that it won't get too soapy.
Pour a gallon of white vinegar onto the load and fill up washer with hot water.
Sprinkle 2 cups of Epsom salt into the mix, making sure that the salt is dispersed among the laundry.
Inspect the wet clothing before drying. If rust stains have yet to dissolve, allow clothing to air dry (preferably in the sun to dissolve rust stains faster). Do not place clothing in the dryer as high heat will cause the rust stains to be permanent. Instead, use a special store-bought stain remover to eliminate the rust stain.
Place rusted fabrics into a bowl of hot water if there is not enough clothing to fill the washer. Add 1 cup of white vinegar and let it soak overnight. Drain clothing and rinse in cold water. Allow garment to air dry.
Invest in a store-bought solution that can remove rust stains from clothing. Read the product's warning label to determine whether the solution will fade the clothing's colour. Remove any dried rust stain residue that is stuck on clothing with a dull knife or metal spatula. Place the garment's rust-stained spot facedown on a towel on a flat surface.
Dampen a cloth with a moderate amount of the stain remover. Pat the stain on the wrong side of the garment. Feather its edges working from the outside in to keep from transferring the rust to other parts of the garment. Allow the stain remover to absorb into the material where the original rust stain is.
Place rust-stained clothing into a washing machine if the rust stain is harder to remove. Add detergent to the washer and wash with hot water. Place the garment into a wash bowl with hot water and allow it to soak overnight. Rinse with cold water and allow garment to air dry.
