- Rinse or sponge with cool or lukewarm water as soon as you can.
- Blot rather than rub or brush.
- Keep hot water and the dryer away until the stain is gone.
- Test any treatment on a hidden spot first.
Discharge leaves yellow or brown marks on underwear because it's a protein-type stain, and heat is what locks it into the fibers. Enzymes and detergent do the real work, so cool water and a patient soak beat anything hot, and the dryer stays off until the mark is gone. Whether the pair is white cotton, a colored fabric, or a synthetic changes how much bleach is an option, and an older mark that has already been dried can take a few rounds to fade.
Scrubbing harder rarely helps with discharge stains on underwear, so let an enzyme pretreater do the work. If the yellow is still there after one soak, repeat the soak instead of turning up the heat. A prewash stain remover stick is handy for targeting just the spot.

How to get discharge out of clothes
Step 1 of 6
Rinse the stain from the back
Hold the stained area under cool running water and let it flow through from the back, so the stain moves out the way it came in. If you can't rinse right away, blot the spot with cool or lukewarm water and keep the fabric damp.
Step 2 of 630 minutes
Keep an enzyme pad on the stain
Mix 1/2 teaspoon enzyme presoak or enzyme detergent into 1/2 cup warm water. Soak a clean pad in the mix, lay it on the stain and keep it moist for 30 minutes, then flush the spot with plain water.
Tip. Re-wet the pad if it dries out before the time is up.
Careful. Enzymes are not for silk or wool, so skip this step on those fibers.
Step 3 of 65 minutes
Work in liquid laundry detergent
Pour liquid laundry detergent over the stain until it is covered and let it sit for 5 minutes. Work it in with your fingers, rinse, and repeat if the stain is still there.
Step 4 of 6
Flush any mark with ammonia
If a mark is still visible, mix 1 tablespoon household ammonia with 1/2 cup water and flush it through the spot, then rinse with plain water. Use this only on a mark the detergent didn't lift, and skip it entirely on silk and wool.
Careful. Rinse the ammonia fully out before anything else touches the spot.
Step 5 of 6
Wash on the hottest allowed setting
Wash the underwear with detergent, non-chlorine bleach and an enzyme presoak, on the hottest setting the care label allows. If the label is missing or you can't read it, use cool or lukewarm water instead.
Careful. Test non-chlorine bleach on a hidden spot first, since colored fabric that is not colorfast can change.
Step 6 of 6
Check before drying, then repeat
Hold the spot up to the light before anything goes near the dryer. If the stain remains, soak the underwear for 1 or 2 days, stirring it now and then, wash it again and let it air dry.

Best products for discharge
Choose a prewash stain remover spray or stick for the spot, and an oxygen bleach powder for the non-chlorine bleach step. Read the label on any bleach before you buy.
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on this fabric, 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.
If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
Rinse the spot from the back and watch the water as it runs: a fresh mark gives up color early. Hold the wet fabric up to light, and if a tint remains, run the enzyme step again instead of moving toward heat. A stain that hasn't budged after two full rounds has set, so switch to the older-marks section.
What changes for yours
Adjust for your fabric
Whites and white cotton underwear
Start white cotton in cool water, since heat is what bakes the mark into the weave. Keep the enzyme step going until most of the mark is gone before you add any warmer water.
If a yellow tint survives, chlorine bleach is the last step, and only when the care label allows it and the cotton is white. Rinse every other product out first, and if the fabric itself starts to look yellow, you've used too much.
Colors and synthetic pairs
Colors and synthetics start with the same cool rinse and enzyme step, and that's where most of the mark leaves. Chlorine is off the table here, so an oxygen-based product is the only one to consider if a trace remains.
Before using it, dab the product onto a seam inside the waistband and blot with a white cloth. If any dye shows up on the cloth, skip the product and repeat the enzyme soak instead.
Silk, wool and delicates
Silk and wool need a lighter touch than cotton, so rinse from the back with cool water and blot gently instead of rubbing. On these fibers, skip the enzyme products, chlorine bleach and ammonia altogether, since each one can damage the fiber.
A mark that survives the gentle rinse is better left to a cleaner, because home products carry the most risk on these fibers. Mention the silk or wool content when you drop it off.
Dry-clean-only items
A dry-clean-only label rules out the sink, so blot away any loose matter with a dry cloth and let the cleaner take the rest. Bring it in quickly, since fresh protein marks respond far better to a cleaner than dried ones.
Name the fabric and the stain when you hand it over, so they can choose the right solvent. Rubbing at home can push the mark deeper into the weave, so keep it to a light blot.
Old, dried or set-in stains
An old stain has had time to set, so the quick rinse won't finish the job on its own. Lift off any crusted matter first, then soak the underwear in cold water with a detergent or an enzyme presoak. Aged stains can need several hours in an enzyme product, so give the soak time instead of checking it every few minutes.
Dried discharge follows the same soak, but it usually needs more than one round before it's fully gone. Work through the cold soak, then repeat the enzyme pad and the wash, checking the spot before it goes near any heat.
If the item has already been through the dryer, the stain is set harder, so expect a lighter result rather than a perfect one. A faint mark can stay after several rounds, and that is the realistic limit with this kind of stain.

Do home remedies work on discharge?
Several common home remedies don't belong in this treatment, and a couple can make the stain harder to lift. Here is how each one fits with the steps above, so you know what to reach for and what to leave on the shelf.

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 + Oxygen bleach (OxiClean)
Poison Control warns against mixing ammonia products with other cleaners, and OxiClean's maker says not to mix it with household chemicals.
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 rub bar soap into a fresh stain
Bar soap sets many stains, so it makes a discharge mark harder to lift. Use liquid laundry detergent or an enzyme product from the steps instead, and keep the bar soap away from the spot.
Don't over-soak the underwear
A soak that runs too long can leave yellow stains that won't come out. Keep the soak to the time given and don't exceed the recommended amount of product.
Don't use ammonia at full strength
Dilute it first, using about a tablespoon of household ammonia to half a cup of water, and rinse it out before anything else touches the spot. Keep it off silk and wool altogether.
Don't skip the hidden-seam test
Try any product on a hidden seam before it goes on the visible mark. If the test area changes in any way, stop and choose a gentler option.
Don't leave the enzyme pad on for hours
The enzyme pad is meant to work for about 30 minutes on the spot. Longer soaking belongs to the whole-item soak used for older marks, so don't stretch the pad to fix a mark that isn't lifting.
When to call a professional
Most pairs don't need a professional, but a delicate or dry-clean-only pair is worth bringing in while the mark is still fresh. Mention the fabric type and whether the stain has been dried, since a cleaner will handle a dried mark differently.
Questions
Is a small mark worth treating?
Yes. Discharge is a body fluid, so it can leave a mark on underwear, and the mark sets if it dries. Treat it while it is still fresh to give the stain the best chance of coming out.
Why does discharge stain underwear?
Discharge is a body fluid, and it belongs to the protein and starch stain group. Protein stains respond to enzymes and detergent rather than heat, so the mark gets harder to lift once it has dried or been through a dryer.
What makes the marks turn yellow or brown?
Discharge is a protein stain, and once it has dried or been heated it sets, leaving a color that is hard to lift. Treating it early, before heat reaches it, gives the color less chance to stay.
Can yellow marks on underwear come out?
It can, especially if you treat it before it dries. The enzyme and detergent steps are built for protein stains, and a stain that has dried may need more than one round before it is fully gone.
How long does an old mark take to lift?
Expect more than one round. Start with a cold soak in detergent or an enzyme presoak, then repeat the enzyme and wash steps and check before the item sees any heat.
Do white marks need different treatment?
No. Whatever the color, discharge is a body fluid, so the cool rinse, enzyme and detergent steps apply the same way. Check the stain before any heat touches it.
