Prep first
Before you start
- Blot any wet residue and remove the rusty object before you treat the stain.
- Work on fresh rust first, since old rust is much harder to shift.
- Apply any commercial rust remover to the stain only, not the whole garment.
Rust on clothes is iron oxide, usually from iron in household water or from a rusting washer drum. Catching it while it's fresh makes a real difference, and the dryer's heat should stay away from the garment until the spot is clear. Washable fabric can handle a salt and lemon treatment, but dry-clean-only items belong with a professional.
Rust stains on clothes after washing usually point to a rusty washer drum or iron-heavy water, so fix the source before you rewash. Rust stains on white clothes and white shirts need a patient, gentle approach, since rough scrubbing can fray the weave. Reach for a fabric-safe rust remover only when home methods fall short, and stop if the fabric starts to fray.

6 steps
Step by step
Step 1 of 6A few minutes
Pretest on a hidden spot
Dampen a concealed area, such as an inside seam, with the rust treatment you plan to use. Wait a few minutes, rinse, and check for any color change before you touch the stain.
Tip. Pick a spot that wouldn't show if the color shifted.
Step 2 of 6
Treat with salt and lemon juice
Sprinkle salt over the rust, then squeeze lemon juice over the salt until the spot is wet. Spread the garment in the sun to dry, then rinse it thoroughly and repeat if the rust is still there.
Step 3 of 6
Boil if the fabric allows it
Only boil fabrics that can take it, which are generally some cottons and linens; skip this step for anything else. Boil the garment in 4 teaspoons of cream of tartar per 1 pint of water until the stain is removed, then rinse thoroughly.
Step 4 of 6
Apply a commercial rust remover
Apply the rust remover to the stain only, then repeat if needed. Rinse the garment thoroughly so no remover stays in the fabric.
Careful. Wear heavy-duty rubber gloves before you open the bottle.
Step 5 of 610 to 15 minutes
Soak white loads in oxygen bleach
For rusty discoloration on a load of white items, add detergent and one cup of oxygen bleach to the water. Soak the clothes for 10 to 15 minutes, then launder them as usual.
Tip. Use this only on white items or colorfast fabric.
Step 6 of 6
Check the stain before drying
Look at the spot in daylight after rinsing. If any rust shows, repeat the treatment that worked before the garment goes anywhere near heat.
Tip. Air dry until you're sure the stain is gone.
Careful. Keep the garment out of the dryer and away from the iron until the stain is gone; heat sets it.

Best products for rust on clothes
Look for a commercial rust remover labeled for fabric, and choose an all-fabric oxygen bleach for white loads. Oxalic acid and hydrofluoric acid removers are harsher, so read the label closely before you buy.
OUT White Brite Laundry Whitener
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on clothes, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light before using any heat. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
See what to do for what you're seeing →Heavy buildup usually takes more than one round.
Heavy or long-standing buildup →When to call a professional →How to tell it's working
The stain is working when it lightens and stops looking sharp-edged after each rinse. Once the color no longer changes and the spot blends into the fabric around it, you're done. If a faint mark remains, repeat the treatment that worked rather than adding more heat.
What changes for yours
Adjust for your clothes
Fabric, cloth, or other material
On most fabrics, start with the salt and lemon treatment in the sun, since it's the method for rust on fabric. Test it on a hidden spot first, because some fabrics can't handle acid.
If you don't know the fiber, start with a cold-water soak and check the care label before you apply anything stronger. Once the label allows it, the commercial rust remover is the next option for a stubborn mark.
White clothes and white shirts
Whites are the one case where the oxygen bleach soak goes straight into the wash, so use it when a whole load has rusty discoloration. Run the salt and lemon treatment on any single spot first, then the soak, so the bleach works on what's left.
Rinse the whites well after the soak and check them in daylight before drying. If a faint mark remains, repeat the salt and lemon treatment rather than extending the soak.
Rust marks on clothes
Rust on clothes shows up as an orange-brown mark that often appears after washing in household water that carries rust, or after contact with a rusting washer drum. Look for marks that match those sources, and check the washer drum for rust before the next load.
If you're not sure the mark is rust, treat it as an unknown stain first. Pretest anything stronger on a hidden spot before you go on.
Jeans and denim
Jeans are tough, so the salt and lemon treatment is the usual first step once the care label confirms the fabric can take it. Blot the rust rather than rubbing it, and save firmer pressure for the thickest part of the denim.
Pretest a hidden spot inside the hem or waistband before you apply a commercial rust remover. If the rust sits deep in the twill, repeat the salt and lemon treatment in the sun rather than adding more product.
Cotton clothes and fabric
Some cottons can take boiling, so the cream of tartar boil is an option once you've confirmed the garment is cotton and the care label allows it. Only use it when the fabric is clearly suited, and skip it for any blend you can't identify.
Cotton can take the salt and lemon treatment and the commercial rust remover, but test each on a hidden spot first. Rinse thoroughly after boiling, and check the stain in daylight before drying.
Swimsuits, wedding dresses, wool, and colored clothes
Wool and spandex can't take chlorine bleach, so skip any bleach and test the salt and lemon treatment on a hidden spot first. Check a swimsuit's care label before you start, since the fiber decides how hard you can work the stain.
Colored clothes can take the oxygen bleach soak only if the color is fast, so test a hidden area and stop if the color changes. A wedding dress or other dry clean only piece belongs with a dry cleaner rather than a home treatment.
Heavy or long-standing buildup
Old rust is much harder to remove than fresh rust, so set your expectations before you start. Begin with the salt and lemon treatment in the sun, which is the first method for rust on fabric.
If the garment has already been through the dryer or an iron, the heat has likely set the stain and it will be tougher to shift. Don't add more heat to test it; keep the item in the sun and out of the dryer while you work.
Some stains fade a lot without disappearing completely, and in some cases rust may become impossible to remove. If a mark still shows after the repeat treatments, take the garment to a dry cleaner rather than trying something stronger at home.
Vinegar, baking soda, peroxide and more
Do home remedies work on rust on clothes?
Many household remedies get suggested for rust, but only a few are worth using on clothes. The salt and lemon treatment and the oxygen bleach soak are useful, while the rest are too weak or can make rust worse.

What makes it worse
Mistakes to avoid
Don't use chlorine bleach on rust
Chlorine bleach sets rust and makes the stain more intense, which can turn a fixable mark into a permanent one. Never mix it with lemon juice, vinegar or any other acid either, because the combination can release toxic gas.
Don't use a rust remover on dry clean only garments
Acid removers aren't a safe home treatment for dry clean only fabric, so don't try one on that label. Show the stain to a dry cleaner instead and tell them it's rust.
Don't leave a rust remover on longer than its label says
Liquid and aerosol pretreatments can damage fabric if they sit too long, so time them by the label and not by guesswork. Rinse thoroughly once the time is up, then check the stain.
Don't use hot water on a stain you can't identify
Hot water can set protein stains such as milk, egg or blood, so it's the wrong move when you don't know what's in the mark. Start with cold water and find out how the stain responds.
Troubleshooting
If the stain is still there
Pick what you're seeing:
The rust faded but a light ring remains
Repeat the salt and lemon treatment and let it dry fully in the sun before rinsing. If the ring holds, move to the cream of tartar boil or a rust remover.
The garment went through the dryer with the stain
Heat makes it harder, not always hopeless. Start the treatments again from the pretest, and expect more repeats than for a fresh mark.
The remover lightened the fabric
Rinse the garment immediately and thoroughly. Stop treating and take it to a dry cleaner, explaining which product you used.
When to call a professional
Take dry clean only items to a professional dry cleaner as soon as you can, and tell them the fiber content and that the stain is rust. Take washable items too if the stain covers a large area, the item is bulky, or the fabric is fragile.
Questions
Are rust stains on clothes dangerous or permanent?
Rust isn't dangerous on its own, but heat can set it and make it permanent. Fresh rust usually responds to the treatments here, while old stains can be very difficult to remove.
Where does rust on my clothes come from?
Usually it's iron in household water or rust shed by a rusting washer drum. If marks keep appearing after washing, check the drum for rust before running another load.
Can I still save a rust stain that went through the dryer?
Often you can improve it, though it's harder than fresh rust. Start with the salt and lemon treatment in the sun, and move to the commercial rust remover if it doesn't lift.
Can I use oxygen bleach on colored clothes?
Only if the color is fast. Test a hidden area first, and if the color changes, don't use it on that garment.
Does vinegar work on rust on clothes?
No, vinegar isn't strong enough for set-in rust on clothes. The salt and lemon treatment or a commercial rust remover is the better choice.
What if nothing changes after the treatments?
Repeat the treatment that worked, rinsing between rounds. If the stain still doesn't lift, a professional cleaner is the next step.
