Prep first
Before you start
- Brush off or vacuum any powdery residue before you wet it.
- Test any product on a hidden seam first.
- Keep ammonia and bleach apart; never mix them.
- Don't dry or iron the item until the mark is gone.
White marks on clothes are usually residue rather than damage to the fabric, and the usual culprits are deodorant, undissolved detergent or mineral deposits from hard water. Marks that are still fresh come out with much less effort than ones that have baked in, and dried or crusted residue has to be softened before it moves. If the tag reads dry clean only, hand the garment to a dry cleaner with the fiber content and the stain named, and skip the home routine.
For white marks on black clothes after washing, work an enzyme laundry pretreater into the spot before the next wash. A white stain on shirt fabric or black jeans responds to a prewash stain remover spray, applied before washing again. White out stains on clothes need dabbing rather than rubbing, so the mark doesn't spread.

6 steps
Step by step
Step 1 of 6
Check the label and test first
Read the care label for the fiber and any limits on washing or cleaners. Dab your chosen remover on a hidden seam and let it dry before you go any further.
Tip. If the label is missing or the fiber is unknown, don't guess: use cold water only and take the item to a dry cleaner.
Step 2 of 6
Brush off any powder first
Vacuum or dry-brush any powdery deposit off the surface. Only wet the mark once the powder is gone, since liquid poured onto dry powder can create more problems.
Step 3 of 6
Dab on ammonia or vinegar
On a new mark, dab a few drops of ammonia onto the spot. On an old mark, use a few drops of white vinegar instead, and blot without rubbing.
Tip. Only plain white vinegar; colored vinegar can leave its own stain.
Careful. Vinegar can weaken or discolor cotton, rayon, acetate and triacetate, so test it first.
Step 4 of 6
Rinse, then rub in dish soap
Rinse the ammonia or vinegar out with cold water before anything else. Then work a little undiluted hand dishwashing liquid into the mark, rubbing sturdy cotton and tough fabric and blotting delicate fabric instead.
Careful. Undiluted dish soap is too strong for silk, velvet and other delicate fabric.
Step 5 of 6
Wash in cold water
Launder the item in cold water on the care label setting, using your usual detergent. Make sure the detergent dissolves fully before the load starts so no residue is left behind.
Tip. Wash dark items inside out to cut down on rubbing.
Step 6 of 6
Air dry and check before heat
Hang the item to air dry, then check the spot in daylight before it goes near any heat. If the mark is still there, repeat the steps or move on to the set-in options below.
Careful. Never dry or iron a stained garment, because heat sets the mark and can make it impossible to remove.

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
A removed mark leaves the fabric looking the same as the rest of the item, with no dull or chalky patch. If the spot looks paler or dull after drying, residue may still be on the fibers, so repeat the cold-water wash before deciding it's permanent.
What changes for yours
Adjust for your clothes
Shirts, pants and other garments
Shirts and pants follow the same steps, but the collar, cuffs and waistband usually hold the most deodorant and detergent residue, so start there. Work the ammonia or vinegar in gently with a soft brush, then rub the dish soap in only where the mark shows.
If the mark is heavy, repeat the dish soap rub before the wash rather than after the dryer. Rinse thoroughly so no soap is left behind to dry as a new white mark.
Correction fluid
Correction fluid is a different kind of mark from residue, so don't assume the steps above will lift it. Let it dry completely, then scrape off the loose flakes with a dull knife or your fingernail before anything wet touches it.
Test a hidden seam with a small amount of dish soap first, and only then work on the mark. If it's still there, take the item to a professional dry cleaner and point out the stain.
Sweaty shirts
Sweat marks on shirts are usually deodorant or antiperspirant residue left in the underarm area, and they show most on black fabric. Start with the ammonia dab on the underarm area, then rub the dish soap in gently over the same spot.
Aluminum and zinc antiperspirant build-up can be stubborn and may need the set-in options. Expect to repeat the cycle on a heavily worn shirt rather than hoping one wash will clear it.
White and colored clothes
On white cotton, the chlorine bleach set-in option is available once the item has passed a bleachability test and everything else is rinsed out. Run the main steps first, and move to the set-in options only if the mark stays.
On colored clothes, skip chlorine and test every product on a hidden seam before use, since unstable dyes can change color or fade. Hydrogen peroxide and oxygen bleach are for colorfast items only.
Washing machine residue
If marks show up on the load after every wash, the cause is usually undissolved detergent or mineral deposits from hard water rather than the stain itself. Check the detergent drawer for clumps and let the detergent dissolve fully before the load starts.
Pull each item out and check it in daylight before it goes anywhere near the dryer, then treat any marks with the steps above. Wash the same kind of load the same way to see whether the marks keep coming back.
Black pants and jeans
Denim and dark pants show residue most along the hems, cuffs, pockets and the front of the thighs, where road salt and deodorant tend to leave marks. Check those areas in daylight before you start, and brush off any powder first.
Work the ammonia or vinegar dab and the dish soap rub only on the marked area so the rest of the leg doesn't get over-wet, then wash in cold water. Check the seams again after drying, since residue can hide in the stitching.
Black shirts
On black shirts, check the collar, cuffs and front panel in daylight first, since residue shows most on dark fabric. Start with the ammonia or vinegar dab, then rinse before the dish soap goes in.
Wash in cold water and check the shirt again before drying. If the mark survives, the set-in options are the next step.
Heavy or long-standing buildup
Fresh stains come out far more easily than old ones, so an old mark that has been through several washes needs a cold-water soak first. Soak the item in cold water, overnight if needed, then repeat the dish soap rub and the ammonia or vinegar dab on the dry area.
If the mark is dry and still there, an all-fabric oxygen bleach soak is the next option for colorfast items; test a hidden spot first and follow the package directions for the amount. On white cotton or other colorfast whites, a 3% hydrogen peroxide solution can go on the spot, and chlorine bleach comes last, diluted and only after a bleachability test and a full rinse.
Heat-set marks are much harder to lift, and a mark that has been through the dryer may stay faint even after every option. Aluminum or zinc antiperspirant build-up may never come out fully, so a professional dry cleaner is the realistic next step for a stubborn spot.

Do home remedies work on white marks on clothes?
Many remedies circulate for white marks, but several are unsafe on dark fabric or do nothing for residue. Here is what each one does on clothes and where it fits in the steps above.

Chemical safety
Never mix these
Some products in this guide react dangerously with each other. Use them one at a time and rinse with water in between.
Ammonia + Vinegar
Poison Control warns that mixing ammonia products with other cleaners is dangerous, and the ammonia maker's safety sheet lists acids such as vinegar as incompatible.
If they mix by accident: Don't use the mixture; ventilate the room and avoid breathing fumes or touching it; call Poison Control at 1-800-222-1222 for disposal advice or if anyone feels unwell.
What makes it worse
Mistakes to avoid
Don't use hot water on an unknown mark
Hot water can set protein stains such as milk, egg or blood, and the mark alone won't tell you which one you have. Stay with cold water until you know the cause and the fabric has passed a test.
Don't use chlorine bleach on dark clothes
Chlorine can strip color from dark or non-colorfast items, and it's never right for wool, silk, mohair, leather or spandex. Keep it for white colorfast cotton as the last option, and never use it at full strength.
Don't rub bar soap into a fresh mark
Bar soap sets many stains, so it makes a fresh mark harder to lift. Use the liquid dish soap instead.
Don't mix ammonia with chlorine bleach
Ammonia and chlorine bleach together release toxic fumes. Rinse thoroughly between any two removers and keep them in separate steps.
Troubleshooting
If the stain is still there
Pick what you're seeing:
The mark faded but a lighter patch remains
The dye may have shifted. Try a few drops of white vinegar on an old mark, after testing, then rinse and launder.
The garment is dry-clean only
Don't wash it. Take it to a dry cleaner within 24 to 48 hours and tell them the fiber content and what the mark is.
A stain remover left its own white spot
Rinse the area well with cool water and launder again. Next time, keep the pretreatment on only as long as its label allows.
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 washable items too if the mark covers a large area, the item is bulky or the fabric is fragile.
Questions
What causes white stains on clothes?
Most white marks are residue from deodorant, undissolved detergent, or mineral deposits left when water dries, and road salt can leave them too. Working out which one you have tells you where to start.
How do I stop white stains on black shirts?
Let deodorant dry fully before you dress, and use only as much detergent as will dissolve in the wash. Check each shirt in daylight after washing, before it goes in the dryer.
Can I use ammonia on black clothes?
Yes, but only on a fresh mark and after a hidden spot test. Rinse it out fully before the dish soap goes on.
Are white marks on clothes permanent?
Usually not, if you treat a fresh residue mark before it dries into the fibers. Marks that have been through the dryer or sat for a long time are harder, and some antiperspirant build-up may stay.
Why do white marks show up after my washing machine runs?
The usual cause is detergent that hasn't dissolved or hard-water mineral deposits left on the load. Let the detergent dissolve fully before the cycle starts, and check the load after each wash.
What do I do about correction fluid on clothes?
Let it dry completely, scrape off the loose flakes, and test a hidden seam before any product touches the mark. If it stays, a professional dry cleaner is the safer choice.
Which stain remover works on white marks on clothes?
Plain hand dishwashing liquid handles most of these marks, and it's the only product the main steps need. For stubborn marks, a professional dry cleaner is the safer next step than a bleach.
