Key Takeaways:
- Act Fast When a Stain Happens: Rinse your underwear in cold water as soon as you notice a stain. Gently blot, apply mild soap, and give it a short soak before washing. Quick care keeps fabric feeling soft and helps prevent stains from setting in.
- Know What to do for Fresh or Dried Stains: Fresh stains respond best to a rinse-and-repeat routine with mild soap. For older stains, give the fabric time to soak, then work the stain gently with your fingers. Patience helps preserve the shape and stretch of your underwear.
- Use Home Remedies That Work: Household items like hydrogen peroxide, baking soda, vinegar, and salt water can lift stains without harsh chemicals. Choose what works for your fabric type, and always rinse with cold water for best results.
There’s nothing unusual about waking up to a spot on your favorite pair of underwear or finding an unexpected leak midday—periods can be erratic, no matter how experienced we are. Leaks are a common part of life for people who menstruate, and it’s time we talk about them openly.
At Saalt, we believe in period care that puts comfort first and values real-life needs, whether that’s dealing with leaks in the moment or relying on breathable period underwear made to move with your routine. This guide offers clear steps for how to get period stains out of underwear, including what to do for fresh leaks, dried stains, and delicate fabrics, so you can care for your garments.
Immediate Steps to Take When a Stain Happens
Period stains happen, sometimes first thing in the morning, other times during an afternoon meeting. The sooner you act, the easier it is to save your favorite pair. A few simple steps can help lift the stain and protect your underwear without stressing your routine.
- Rinse with Cold Water: Hold the stained area under cold running water as soon as you can. Cold water helps break down the blood before it sinks into the fabric. Skip hot water—heat can bind the proteins in blood and make stains harder to treat.
- Gently Blot, Don’t Rub: Use a clean, damp cloth or paper towel to blot the area. Press lightly to absorb the blood instead of rubbing, which can spread the stain and push it deeper into the fibers.
- Apply a Mild Soap Solution: Work in a small amount of gentle, unscented soap using your hands. Focus on the stained area and lather lightly. Let the soap sit for a few minutes so it can begin to lift the blood without irritating sensitive fabrics.
- Rinse Again: After letting the soap work its magic, rinse thoroughly under cold water until no more blood lifts from the fabric. Take your time here, as thorough rinsing prevents leftover residue and odors.
- Set Aside Before Washing Normally: Drop your underwear into a bowl or sink of cold water and let it soak for up to 30 minutes. This extra step gives any remaining stain time to loosen before you wash it with your regular laundry.
Your Go-To Guide for Period Stain Removal
Period stains show up when you least expect them—during an extra-long meeting, while running errands, or even mid-nap. Once you know how to use period underwear, you’ll also know how to get blood out of underwear the right way. After all, quick rinses, mild soap, and air drying are all part of the routine. Here’s a breakdown that covers both new and stubborn stains.
1. Rinse With Cold Water Immediately
Rinse the stained area under cold running water as soon as possible. Cold water helps keep the blood from bonding with the fabric. Gently rub the fabric against itself to loosen the stain—no need to scrub aggressively. For dried stains, let the underwear soak in cold water for at least 30 minutes to help soften the area before treating it.
2. Apply a Stain Remover or Mild Soap
Apply a small amount of unscented soap or a stain remover that’s safe for sensitive fabrics. Massage the product into the stain with your fingers and let it sit for 10 to 15 minutes. For set-in stains, you can let it rest a bit longer, up to 30 minutes. A gentle approach here helps preserve the stretch and softness of your underwear.
3. Gently Scrub the Stain
Use your fingers or a soft-bristled brush to work the soap into the fabric. Focus on the stain, but avoid scrubbing hard. For older, heavier stains, apply a second round of soap and repeat the process slowly. Circular motions can help lift the blood without pulling at seams or thinning the weave.
4. Rinse Until Clear
Rinse thoroughly with cold water until no soap remains and the water runs mostly clear. Any lingering residue could lead to odor or fading later. With heavier stains, don’t worry if you need to rinse twice—it’s worth the extra step.
5. Repeat As Needed
If you’re still seeing color after the first wash, repeat the soap and rinse cycle. Long-term stains often need a second or third pass to fully lift. Letting the underwear soak overnight in cold water with a bit of gentle detergent can make a big difference when tackling deep discoloration.
6. Air Dry
Skip the dryer. High heat can lock in trace amounts of blood and break down the fabric’s elasticity over time. Instead, hang your underwear to dry in a cool, well-ventilated area. For moisture wicking underwear designed to stay dry and odor-free, air drying also helps maintain absorbency and shape.
Effective Home Remedies for Blood Stain Removal
Period leaks happen to all of us. When you spot a blood stain on your underwear, acting quickly and using the right methods can make all the difference. Here are reliable approaches to help get period blood out of underwear using household essentials:
- Cold Water Rinse: Rinse the stain under cold running water as soon as possible. Cold water helps keep the blood from settling into the fabric. Rub the material gently against itself to loosen the stain.
- Fragrance-Free Soap or Mild Detergent: Apply a small amount of unscented soap or mild detergent directly onto the stain. Work it in with your fingers, rinse well with cold water, and repeat as needed.
- Hydrogen Peroxide (3%): Hydrogen peroxide is especially effective on fresh stains. Dab a small amount onto the affected area, let it fizz for a minute or two, then blot with a clean cloth. Once you’re done, rinse with cold water.
- Baking Soda Paste: Mix one part baking soda with two parts cold water to form a paste. Spread it onto the stain and let it sit for at least 30 minutes before rinsing. Baking soda’s gentle abrasiveness and natural deodorizing qualities help lift the stain while neutralizing odor.
- White Vinegar Solution: Combine equal parts white vinegar and cold water, then soak the stained underwear for 30 minutes. After soaking, gently rub the fabric together and rinse well to break down the blood.
- Salt Water Soak: Stir one tablespoon of salt into two cups of cold water. Soak for a few hours or overnight, then rinse and wash as usual.
Tips for Different Fabric Types and Colors
Removing period blood from underwear doesn’t look the same across all fabrics or shades. Different materials and colors deserve tailored care to keep them looking and feeling their best. Here’s what we recommend for the most common types:
Cotton
Cotton’s breathability makes it a favorite for everyday underwear. Act quickly: run cold water through the stain as soon as possible, and use a gentle, unscented soap or a little mild detergent. Gently rub the fabric together rather than scrubbing, which can stretch or damage the weave.
Microfiber and Synthetics
These fabrics are smooth and quick-drying but can be trickier to clean if stains set in. Start with a cold-water rinse. For persistent spots, apply an enzymatic stain remover or a tiny bit of diluted hydrogen peroxide, letting it sit for no more than 10–15 minutes before washing. Avoid heat, as it can set stains on synthetic blends.
Wool or Delicate Fabrics
Wool and delicate blends require special attention. Instead of streamlining your approach, spot-treat with a gentle, wool-safe detergent, dabbing rather than rubbing. Use only cold water and avoid twisting or wringing to preserve the fabric’s structure.
Darker Colors
While stains are less visible on black or deep-colored underwear, they still benefit from quick clean-up. Stick to cold water and avoid heavy-duty bleaches, which can cause fading and weaken fabric over time. Overall, these tips also apply if you’re trying to figure out how to get period blood out of pants made with similar fabrics.
Light Colors and Whites
Crimson stains stand out most on paler underwear. Immediate rinsing with cold water is essential. For any lingering marks, a small amount of diluted hydrogen peroxide can help lift the stain, but always spot test first to avoid unwanted bleaching. Finish with a gentle wash and air dry in the shade.

Frequently Asked Questions About How to Get Period Blood Out of Underwear
What’s the best way to get period blood out of panties without damaging the fabric?
If you're wondering how to get period blood out of panties without ruining softness or stretch, cold water is your best friend. Start by rinsing the stain immediately, apply a gentle soap or enzyme cleaner, and avoid heat when drying. These steps help protect your favorite pairs and make them last longer.
Are there any natural remedies for removing blood from fabric?
Yes, several natural options can help lift period blood stains from underwear. Cold water is your best first step. After rinsing, you can gently rub in salt or baking soda, to help lift the stain. Lemon juice can also act as a mild bleach for light-colored fabrics. Just be mindful that natural remedies may not always completely remove stains, especially if they’ve set in.
Is it okay to put stained underwear in the washing machine?
Yes, but there’s a right way to do it. Rinse the stain in cold water first. Pre-treating the area before tossing your underwear in the washing machine increases your chances of a clean result. Always use cold or lukewarm water for the wash cycle, and avoid hot temperatures, as those can set the stain. For reusable, leakproof underwear like ours, follow the care instructions.
Can enzyme-based cleaners help with period blood stains?
They can be very effective. Enzyme-based cleaners are specifically designed to break down proteins and organic stains, which makes them well-suited to tackling period blood. After rinsing your underwear in cold water, apply the enzyme cleaner to the stain, let it sit for 15–30 minutes, then wash as usual. Always check that your cleaner is safe for use on delicate fabrics and avoid products with harsh chemicals.
What should I avoid doing when trying to remove period blood stains?
There are a few key things to steer clear of:
- Avoid hot water, as it can set the stain permanently.
- Skip harsh detergents and bleach, which can damage fabric and irritate sensitive skin.
- Don’t rub too vigorously, as this can spread the stain further into the fibers.
