Prep first
Before you start
- Blot the spot with a clean white cloth, working from the edges toward the center. Don't rub.
- Find the fiber and care label before you pick a product.
- Stains keep coming back until the water is treated, so have the well water tested by a certified lab.
Iron from well water shows up on clothes as orange-brown marks, while manganese leaves black or dark gray ones, and both hold on tighter than ordinary dirt. Regular detergent won't lift them, and chlorine bleach can set them more firmly, so check the care label before you pick a treatment. Fresh marks respond far better than old ones, so keep the garment out of the dryer until the mark is gone.
If the iron mark on your shirt is still there, rub a prewash stain remover spray or stick into it before the wash. Choose the product for the fabric, and reach for an enzyme laundry pretreater if a faint shadow stays after one pass. Repeat the treatment on a stubborn spot rather than moving on to the dryer.

5 steps
Step by step
Step 1 of 5
Check the label and test
Put a little of the rust remover on a concealed spot, such as an inside seam, and check for any color change before you treat the stain. If you're unsure about colorfastness, this test shows you the result before the stain is at risk.
Careful. Read the care label first; don't use products or procedures it prohibits.
Step 2 of 5
Try the salt and lemon treatment
Sprinkle salt over the stain, then squeeze lemon juice onto it. Spread the garment in the sun to dry, then rinse it thoroughly.
Tip. If a shadow of the stain remains after rinsing, repeat the treatment once before you move on.
Step 3 of 5
Apply the commercial rust remover
Apply the rust remover carefully and follow the manufacturer's directions, then rinse the area thoroughly. If the stain is still there, repeat the application before you move to the soak.
Careful. Oxalic acid is poisonous; wear rubber gloves and keep the remover off your skin.
Step 4 of 510 to 15 minutes
Soak rust-tinged whites in oxygen bleach
For a whole load of white items with rust-colored discoloration, add detergent and one cup of oxygen bleach to the water. Soak the clothes for 10 to 15 minutes, then launder them as the care label allows.
Careful. Oxygen bleach is for colorfast fabrics only; keep it off wool, silk and leather.
Step 5 of 5
Launder and check before drying
Launder the item as the care label allows, then check the stain while the item is still damp. If any mark is left, go back to the treatment that fits it rather than moving on to the dryer.
Tip. Good light makes faint marks easier to see.

Best products for iron on clothes
Pick a rust remover labeled for fabric and an all-fabric (oxygen) bleach for the soak. Leave out any cleaner made for surfaces other than fabric.
Utopia Kitchen White Flour Sack Towels
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
Check the stain in good light after each round, and look for it to fade before you move on. If the fabric's color starts to change, stop, rinse the item and choose a gentler product for the next round.
What changes for yours
Adjust for your clothes
White clothes and shirts
White cotton and linen can take the full sequence, so start with the salt and lemon treatment and move to the rust remover if the stain holds. For rust across a whole load of whites, the oxygen bleach soak is the right step, and it's the one to use when the discoloration covers more than one item.
On a single white garment, the soak is still an option after the rust remover, as long as the care label allows it. Boiling is covered in the set-in section and only fits boil-safe white cotton or linen.
Well water rust
Well water stains often come back after washing, because the metal dissolved in the water keeps depositing rust on laundry. Treating one garment fixes that item, but the next load can get marked the same way.
Until the water is treated, check each load in good light before you put it away. Expect some marks to return, even after a clean result on one item.
Shirts
On a shirt, test the rust remover on an inside seam or hem, since the front is where the stain shows most. Put a clean white cloth under the stain so the rust doesn't spread onto the back of the shirt.
Blot with a clean white cloth rather than rubbing, and keep the sleeve or placket flat so the treatment doesn't wick onto the rest of the shirt.
Jeans
Denim is sturdy enough for the full set of steps, but dark denim may not be colorfast, so the inside seam test matters more here. Repeat the rust remover if the stain is still there after rinsing.
If the color shifts on the test spot, skip the soak and take the jeans to a dry cleaner promptly. Point out the stain and the fabric so they can choose the right method.
Polyester, cotton and other fabrics
Cotton and linen can take the full set of steps, and boil-safe white cotton or linen has the boiling option in the set-in section. For other fabrics, the care label decides what's allowed before anything else.
Don't guess at the fiber, since the steps depend on it. Use the care label to decide which steps apply, and test on a hidden spot before any product.
The laundry marks from appliances
The steps above are for rust from well water, so they don't address a scorch or mark left by the appliance itself. Check what the mark looks like and what it was touching before you choose a treatment.
Take the item to a dry cleaner promptly if the mark covers a large area or the fabric is fragile. Mention how the mark formed so they can pick a method.
Black, brown, orange or yellow stains
Orange-brown and reddish-brown stains are rust from the water, and the rust remover and oxygen bleach soak handle them. Black or dark gray-to-black stains come from manganese in the water, and the same steps apply.
A yellow stain doesn't match either description, so start with the salt and lemon treatment and see how it responds before using a stronger product. If it doesn't respond, test the rust remover on a hidden spot before you use it on the stain.
Colored and black clothes
On colored and black items, the hidden-spot test is the most important step, since a color change there tells you to stop. Work from the edges of the stain toward the center and blot rather than rub.
Once you see a change, stop the treatment and rinse the item. Check the spot in daylight before you go on with any other product.
Heavy or long-standing buildup
Old iron stains take longer than fresh ones, and they usually need more than one round. Start again with the salt and lemon treatment, then move to the rust remover once the first round is rinsed out.
Once a stain has dried, it has set more deeply, so each round may lift less than the one before. If the item has already been through the dryer, the heat has set the stain, and it may not come out completely; a lighter mark is a realistic result.
On boil-safe white cotton or linen that's still stained, boil the item in 4 teaspoons of cream of tartar per 1 pint of water until the stain is removed, then rinse it thoroughly. If the fabric isn't boil-safe, or the stain is still there after that, take the item to a dry cleaner promptly.

What makes it worse
Mistakes to avoid
Don't use chlorine bleach on this stain.
Chlorine bleach can set iron and rust stains or make them more intense, which can make them permanent. Keep it out of the washer for this stain, even on a white load.
Don't dry or iron the stain.
Heat sets the stain, and it can become impossible to remove. Keep the item out of the dryer and away from the iron until the stain is gone.
Don't rub the stain with bar soap.
Soap sets many stains, so bar soap makes a fresh stain harder to remove. Use the salt and lemon treatment instead.
Don't mix rust removers with bleach or other cleaners.
Mixing products can create toxic fumes, so rinse thoroughly between each remover and never combine them in one bucket. Give the item a full rinse before you switch to a different product.
Troubleshooting
If the stain is still there
Pick what you're seeing:
The stain is still there after salt and lemon juice
Repeat the treatment if necessary, then switch to a commercial rust remover labeled for fabric and follow its directions. Check the mark while the garment is wet, and air-dry rather than machine-drying it if any trace remains.
A whole load of whites came out rust-tinged
Add detergent and one cup of oxygen bleach, soak for 10 to 15 minutes, then launder. Pretest a hidden area first if not every piece in the load is colorfast.
The pretest changed the color of the fabric
Stop: that product is not safe for the garment. Rinse it out and take the item to a dry cleaner, pointing out the stain and what you used on it.
When to call a professional
Take 'dry-clean only' items to a professional dry cleaner promptly and tell them the fiber content and the stain. Take even washable items to the dry cleaner if the stain covers a large area, the item is bulky, or the fabric is fragile.
Questions
Does Iron or Well Water Stain Clothes?
Yes. Iron and manganese from well water leave reddish-brown or dark gray-to-black marks once they meet air, and they can hold on through a normal wash. The water can run clear at first, and the color only appears once the iron meets air.
How do I prevent iron stains on laundry?
Prevention starts with the water, so have it tested by a certified lab and choose a treatment system based on the results. Until then, treat stains as soon as you see them, since fresh stains come out more easily than old ones.
Will vinegar get iron stains out of clothes?
No, vinegar isn't needed for iron stains on clothes. Use the salt and lemon treatment first, then a rust remover. If the stain holds after that, the oxygen bleach soak is the next option for whites.
Do I need a special detergent for iron stains?
No. Any laundry detergent can go into the oxygen bleach soak, but the rust remover and the oxygen bleach are what lift the stain.
What if the mark came from my own pressing iron?
The rust steps target rust from water, so they may not help with a mark from the appliance itself. Ask a dry cleaner to look at it, and say what caused it.
How long should I leave the rust remover on?
Follow the manufacturer's directions, since they set the time for their product. Gels on bright or fluorescent items should come off after a few minutes, because unstable dyes can change color or fade.
Is it safe to use these steps on polyester?
Check the care label before anything else, because it sets what's allowed for the fabric. If the label doesn't settle it, take the item to a dry cleaner rather than guessing.
