Rust stains on clothes are among the most difficult stains to remove.
That said, all is not lost if you notice rust stains on clothes after washing them. Regardless of the source of the rust, if you're patient with the stain-treating process, in most cases it is fixable.
You'll need to patient with your stain removal methods - meaning you may have to treat a rust stain several times before you see results.
But your efforts will be rewarded with clothes you can actually wear again. Here are some effective method for removing rust stains from clothes.
There are products designed to get rid of rust stains on clothes that are available at grocery stores and online that are both effective and safe for most fabrics.
The main ingredient in these rust stain removers is an acid - usually oxalic or hydrofluoric acid - that loosens the iron from the fabric so it can be removed in the wash water.These products, such as Whink Rust Stain Remover, are aggressive and can be toxic to the skin, so it is important to follow usage instructions carefully and keep them away from the kids. For that reason, here are a few less-toxic alternatives you can use to remove rust stains on clothes at home.
Start by brushing off the excess rust stain on the fabric surface.
Create a rust stain solution by combining 3 tablespoons of baking soda per gallon of cold water, and add a capful of laundry detergent. Apply the solution directly onto the stain, and let sit for at least 30 minutes.
Without rinsing the detergent solution, place the stained garment in the washing machine, and wash as usual in the warmest laundry temperature safe for the fabric.
You can also use lemon juice with a spoonful or salt or baking soda to remove rust spots on clothes. Create the mix, and apply directly to the rust stain.
Allow to sit for up to two hours (in the sun, if possible.) Then rinse the mixture from the garment, and wash as usual.
Boil a solution of 10 teaspoons of cream of tartar to one gallon of water in a pot free of any rust (using enough water to submerge the garment).
Place the stained item in the boiling water and soak for 10 to 20 minutes. If some rust remains, empty the water and repeat the treatment. For really tough rust stains, follow this treatment with an overnight soak of the garment in laundry detergent and hot water.
Once the stain has lifted, wash the garment in the hottest water safe for the fabric. And be sure the stain is gone before tossing it into the dryer, as any remaining stain will set in the dryer cycle.
Vinegar - a staple in most kitchens - is another effect product for removing rust stains. Apply white vinegar directly to the stained area, and cover it with a layer of salt. Leave it to dry in the sun. When dry, rinse to remove the vinegar and salt and check to ensure the stain is gone. Then wash the garment as usual, choosing the hottest temperature that is safe for the fabric.
