Prep first
Before you start
- Work out the cause first: where the mark sits, how it smells and feels, and when it showed up decide the treatment.
- Brush or vacuum dry soot and mildew before wetting them.
- Test any cleaner on a hidden spot first.
Black marks on white clothes after washing can look the same, but they come from different causes: soot, mildew, manganese in well water, rubber from heels or tires, or greasy residue. Some are damage rather than dirt, and those may not come out fully. What you can expect is a treatment that depends on the cause, and it works best when the mark is still fresh.
Before you get black stains out of white clothes, check the fabric, since spandex and dry-clean-only pieces need gentler products. A prewash stain remover spray or an enzyme laundry pretreater is the usual move once you know the cause. Keep the garment out of the dryer until the mark is gone, because heat can set it for good.

5 steps
Step by step
Step 1 of 5
Brush off dry soot or mildew
Brush or vacuum off any dry soot or powdery residue before the fabric gets wet. Wetting it first can work the mark deeper into the weave. If the residue is mildew, brush it off outdoors, then move on.
Step 2 of 5
Lift the grease with talc
Dust talcum powder over the mark so it can absorb as much of the grease as possible. Once it has done its work, brush it off thoroughly so no powder is left in the fibers.
Step 3 of 5
Pre-treat and soak the mark
Work a commercial pre-wash spot and stain remover into the mark, following its label. If you don't know the cause yet, soak the item in cold water first, since cold is the safe start for an unknown stain.
Tip. Test the remover on a hidden seam before you use it on the mark.
Step 4 of 5
Wash in the hottest safe water
Launder the item in the hottest water the care label allows, using heavy-duty liquid detergent. Check the mark before anything else goes near it, and if any of it remains, repeat the spot treatment and wash again.
Careful. Heat sets the stain, so keep the item out of a hot dryer and off the iron until the mark is gone.
Step 5 of 5
Finish with bleach on whites
If the mark is still faint after the wash, finish with bleach as the last step, once everything has been rinsed out. Chlorine bleach suits cotton, linen or polyester whose label allows it, and oxygen bleach is the choice for whites with spandex. Dilute the bleach first and never use it at full strength.
Careful. Chlorine bleach intensifies manganese and iron marks, so skip it until you know the mark is neither.

Best products for black stains on white clothes
Look for a pre-wash spot and stain remover made for clothing, and choose an oxygen bleach if your whites contain spandex.
Clorox 2 Laundry Stain Remover and Color Booster Powder, 49.2 Ounces
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on white 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.
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 mark that is lifting will look paler after each pass, and the fabric around it will stay clean. If it doesn't change after the full treatment, the stain may be one that can't be fully removed, so check the set-in options and the professional notes.
What changes for yours
Adjust for your white clothes
Cotton, linen and polyester whites
These whites can take chlorine bleach, so it goes in the last step, after everything is rinsed out. Dilute it, and use it only if the care label allows bleach.
If the mark still shows after the bleach, rinse well before you decide whether to repeat that step.
Whites with spandex
Chlorine bleach is not an option for these, so the last step uses an oxygen bleach instead. Test it on an inconspicuous area first.
The rest of the method stays the same, from the talcum powder through the hot wash.
Wool and silk whites
Skip chlorine bleach, oxygen bleach and enzyme presoaks, since none of them suits these fibers. Blot the mark rather than rubbing it.
Use a dry-cleaning solvent on the spot from the wrong side of the fabric, and let it evaporate before the next step.
Dry-clean-only whites
These are better left to a dry cleaner than to the washing machine. Read the care label first, and skip any product it prohibits.
If you can't tell what fiber the item is, don't guess, since the right treatment depends on it.
Whites that picked up dye
Whites that picked up dye from other items can be treated with a color remover. Pretest it on a hidden spot first.
Use the color remover before the bleach step, and rinse everything out before you decide what comes next.
Marks from manganese in well water
Treat the stain with the steps above, but expect it to return on each wash until the water is fixed. Manganese marks come back for as long as the source stays in the water.
Ask whoever tests your water about manganese before you assume the fabric is ruined.
Heavy or long-standing buildup
Old black marks are harder than fresh ones, and the longer a mark has sat, the less likely it is to lift completely. A dried-on mark needs its crust scraped or brushed off before anything else touches it.
If heat has already set the mark, the first pass may not be enough, so plan on a second round of the treatment. A stain that has been through a dryer is usually the hardest kind to clear.
If it is still there after the full treatment, an enzyme presoak overnight or a color remover can help, depending on the stain. Some marks don't come out completely, so aim for a big improvement rather than perfection.

Do home remedies work on black stains on white clothes?
Most home remedies don't suit black marks on white clothes, and several can damage the fabric or react with bleach. The treatment above uses only the products that match this stain, so the rows below show what to leave out and why.

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.
Chlorine bleach + Oxygen bleach (OxiClean)
Both makers advise against combining them: OxiClean says not to mix it with chlorine bleach, and Clorox says the two bleaches cancel each other out.
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 mix bleach with ammonia or vinegar.
Never mix chlorine bleach with ammonia, which gives off toxic fumes, or with an acid such as vinegar. Rinse thoroughly between each product, and don't combine an enzyme presoak with chlorine bleach either.
Don't rub the mark hard.
Blot rather than rub, since excessive rubbing wears the fabric down unless it is tough and durable. Colored sponges and paper towels can bleed dye onto white fabric, so use a clean white cloth instead.
Don't rub bar soap into a fresh mark.
Bar soap sets many stains, so keep it away from a fresh mark. Use the heavy-duty liquid detergent from the wash step instead.
Don't skip the hidden-spot test.
Test each cleaning agent on a hidden area first, and read the care label before using any product it prohibits. A quick test can save the whole garment.
Don't overdo the soak.
Soaking too long or using more product than recommended can leave yellow stains that cannot be removed. Measure the amount, follow the label, and stop when the time is up.
When to call a professional
Take dry-clean-only items to a dry cleaner within 24 to 48 hours, and tell them the fiber and the stain. Take washable items too if the mark covers a large area, the item is bulky, or the fabric is fragile.
Questions
Why do black marks appear on white clothes after washing?
They usually come from something the wash picked up: soot, mildew, manganese in well water, rubber from shoe heels or tires, or greasy residue. Work out the likely source first, since each one needs a different approach. Rubber from shoe soles is its own case, so see the Shoes & Sneakers guide for that.
Can I use chlorine bleach on black marks?
Only after you know the mark isn't manganese or iron, since chlorine bleach intensifies those. Even then, use it as the last step, diluted, on whites whose label allows it.
What if the black mark is from mildew?
Brush off the mildew before you wet it, and do that outdoors. Then follow the steps in order, since mildew left in the fabric keeps growing.
Will a black mark come out once it has dried?
It can, but dried marks are harder. Scrape or brush off any crust, then soak in cold water with detergent or an enzyme presoak before you wash.
Can I use an oxygen bleach instead of chlorine?
Yes, on whites that contain spandex, where chlorine isn't a fit. Use it as the last step, and test it on a hidden area first.
What if the mark is still there after the wash?
Repeat the spot treatment and wash again if the stain remains. If it still shows, it may be a stain that can't be fully removed, and a dry cleaner can take a look.
Does well water cause black marks on clothes?
It can, when the water carries manganese. The marks keep returning until the water is treated, so washing again won't stop them.
