Prep first
Before you start
- Rinse the spot with plenty of water right away.
- Leave the bleach alone and don't try to fix it with another product.
- Keep the underwear out of the dryer and off the iron.
- Expect to hide the spot rather than remove it, because lost color doesn't come back.
A bleach spot on underwear is color that has been taken out of the fabric, leaving a lighter patch where the dye was destroyed. Chlorine bleach does this, and so does benzoyl peroxide from acne medicines and skin creams, which can leave a rusty or yellowish patch. Once the dye is gone, the job is camouflage rather than cleaning.
If bleach stains in underwear keep showing up, the source is still in your laundry, so check nearby loads. Black underwear and colored pairs can be matched with a permanent marker, though the ink fades and needs touch-ups. Keep bleach away from the wash to stop new marks.

5 steps
Step by step
Step 1 of 5
Rinse the spot right away
Rinse the spot thoroughly with water, or run the underwear through a rinse cycle. This stops further bleaching, so the light area doesn't grow while you decide what to do.
Careful. Don't add ammonia, vinegar or other cleaners to try to cancel the bleach. Toxic gas can form.
Step 2 of 5
Let the spot dry and check it
Let the underwear dry and look at the spot once it's dry. The light area is permanent color loss, and regular bleach discoloration can't be reversed.
Careful. Keep it out of the dryer and away from the iron. Heat sets the stain and may make it impossible to remove.
Step 3 of 5
Color in black spots
On black underwear, color the light spot with a black permanent marker until it blends into the fabric around it. Let the ink dry before you wear or wash it.
Tip. Test the marker on a hidden seam first.
Step 4 of 5
Match other colors with a marker
On colored or patterned underwear, pick a fabric marker or felt pen that matches the color around the spot. Color the light area in short strokes so the ink doesn't pool.
Step 5 of 5
Refresh the ink as it fades
Marker ink fades with washing and wear, so the light area will reappear over time. Reapply the same pen to the spot whenever it does.

Best products for bleach spots on underwear
Use a black permanent marker for black underwear and a fabric marker or felt pen that matches the color for everything else. Test it on a hidden seam first, then keep the same pen for touch-ups.
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 underwear, 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
You'll know the marker is working when the light patch blends into the fabric around it and the edge no longer stands out. If the color looks uneven or the ink streaks, let it dry, then add a thin layer rather than a heavy one.
What changes for yours
Adjust for your underwear
Black underwear
Black underwear takes a black permanent marker, and it's the easiest case to hide. Color the light area in short strokes until the spot blends with the fabric around it.
Let the ink dry fully before you wear or wash it. Reapply the marker as the ink fades, since washing wears it down over time.
Colored or patterned underwear
Choose a fabric marker or felt pen that matches the surrounding color as closely as you can. If you're unsure, bring the underwear to an art-supply store to test colors.
Color the light area in short, light strokes and let it dry before you wear it. Keep the same pen for touch-ups as the ink fades.
Underwear with spandex or elastic
Underwear with spandex or elastic can't take chlorine bleach, so don't use bleach to even out the color on it. Stick to the marker steps only, and check the care label for the fiber content before you start.
Spandex is damaged by bleach, so the only fix is a matching pen on the light area. Reapply it as the ink fades.
Cotton canvas sneakers
Evening out color with bleach can suit canvas sneakers, but that approach belongs to shoes, not underwear. The Shoes & Sneakers guide covers the canvas steps in full.
Don't carry that method over to underwear, where the same bleach can damage elastic. Stick to the marker steps for your underwear instead.
Spots that keep appearing in the wash
If new bleach spots keep appearing on dark clothes after washing, the washer may be the cause. The liquid-bleach dispenser can carry bleach into the load, so check it and make sure it's clean and free of bleach.
Keep bleach out of the wash with dark underwear until you've checked it. Then rinse any new spot with water as soon as you see it.
Heavy or long-standing buildup
Old or new, a bleach spot is permanent color loss, so soaking or scrubbing won't bring the color back. Bleach changes the dye itself, which is why the light area stays light even after it dries. The realistic goal is camouflage, not removal.
Once it has dried, the spot looks the way it will look for good, so there's nothing to gain by working at it. Keep the underwear out of the dryer and away from the iron, because heat can set whatever else is on the fabric.
If the spot is still there after the dryer, go back to the marker steps and reapply the pen as the ink fades. Another round of bleach isn't an option on underwear, since spandex and elastic can't take it, and it only adds new light spots.
Vinegar, baking soda, peroxide and more
Do home remedies work on bleach spots on underwear?
Most home remedies you'll find online are for spills, not bleach spots, because they lift something off the fabric and can't put color back. The ones below either don't help or can make the light area worse, so the steps above are the way to go.

What makes it worse
Mistakes to avoid
Don't try to bleach the rest to match
Using more bleach to even out the color weakens fabric, and underwear with spandex or elastic can't take chlorine at all. You'll end up with new light spots instead of a match.
Don't scrub or soak the spot hoping for color
Scrubbing and soaking won't bring back lost dye, and rubbing can wear down the fabric around the spot. Spend that time on the marker instead.
Don't skip the test on colored underwear
Marker ink can look different on colored fabric, especially if the fabric isn't colorfast. Test the pen on a hidden seam and let it dry before you wear the underwear.
When to call a professional
If the underwear is dry-clean only, take it to a professional dry cleaner promptly and tell them about the bleach spot and the fiber content. Ask them to check the fabric before any treatment is applied.
Questions
Can bleach spots on underwear be removed?
No. Bleach takes the color out of the fabric, and that loss is permanent, so no cleaner will bring it back. Rinse the spot with water right away, then hide it with a matching marker.
Will vinegar or baking soda fix a bleach spot?
No. Neither one restores dye, so neither can lift the light area. Use a matching marker to hide the spot instead.
Can I bleach the rest of the underwear to match?
Not safely. Chlorine bleach can't go on spandex, elastic, wool, silk or leather, and underwear often has spandex or elastic. A second bleach treatment usually just makes new light spots.
What marker works best on black underwear?
A black permanent marker. Color the light area until it blends into the fabric, let it dry, and reapply as the ink fades.
Does heat make a bleach spot worse?
Yes. Heat can set the stain and may make it impossible to remove. Keep bleached underwear out of the dryer and away from the iron.
Why do bleach spots keep appearing on my dark underwear?
The washer may be the cause. The liquid-bleach dispenser can carry bleach into the load, so check and clean it before the next wash.
Can rubbing alcohol remove a bleach spot?
No. Alcohol can't put color back, and it can change the color of untested dyes. Keep it off underwear and use a matching marker instead.
