How to Get Period Stains out of Underwear


For some of us, it’s a monthly reality. For others it might be an occasional inconvenience. Regardless: When you get period stains on your underwear, it’s not the end of the world! Here's how to get blood out of your clothes.

First Things First: Blood Stains Happen

There’s still a lot of stigma and shame around reproductive health. This means many people find it painful to talk (even with friends!) about things like period stains on their underwear.

Some of us end up routinely tossing our favourite undies. Some of us spend our period days wearing underwear we’ve designated as “ruinable”. 

But it doesn’t have to be this way. 

What’s more: You probably already have everything you need lying around. Stick with us!

How to Remove Blood Stains

Act Swiftly, If You Can

The fresher the stain, the easier it will be to ensure you get all the period blood out of your underwear. We know it’s not always possible to act immediately, but if you can, do it.

Avoid just tossing your undies in your hamper and waiting for laundry day to come around.

You’ll probably be amazed how much of the stain comes out of your underwear if you get to it when it’s fresh.

Ignore the Hot Water Tap: Go for Cold

The biggest mistake people make when trying to get period blood out of underwear is to run the hottest water possible over it. 

It’s a natural instinct. We wash dishes in hot water for a good reason, right? But hot water can have the opposite effect on fabric and cause stains to set in, making them even more difficult to remove.

Instead, go for ICE COLD water. Run it over the stain for a few minutes, letting the running cold water do the work. Odds are, you’ll see a lot of the period blood wash away from your underwear right away!

Kill the Stain with Kindness

If the stain is a little more stubborn, you might be tempted to put some muscle into it. But remember: Underwear is made of delicate fabrics. This is especially true if you’re handling your favorite Knix underwear.

But even your daily underwear can be easily stretched if you treat it too roughly. So, don’t work up a sweat scrubbing aggressively.

Instead, try gently using your nails, or an old soft toothbrush to gently scrub the area where the blood set on your underwear. If you use soap, choose soap designed for delicate fabrics.

(Did you notice we said gently twice in that last sentence? We mean it… GENTLY)

Stain Removal Products Can Help

If you need to up the ante, reach for your household stain removal products. Read the product instructions to make sure they can be used on the fabric of your underwear.

And remember: Products with bleach are generally not to be used on darker fabrics.

Again, work in the product gently. That old toothbrush can be a handy tool here as it allows you to pinpoint the exact area where there’s period blood on your underwear.

Follow the instructions: If you need to leave the product sit before rinsing, do.

MacGyver It With These Household Products

No stain-removal products at home? Don’t worry. You can even figure out how to get blood out of underwear with some household products!

1. Hydrogen Peroxide

Hydrogen peroxide is a common antiseptic, so you might find you have some in your medicine cabinet. But you may not know that hydrogen peroxide is also very effective for stain removal.

Note: Hydrogen peroxide is a bleach so should only be used on light-colored panties. Avoid using hydrogen peroxide on any dark color fabrics.

Pour some hydrogen peroxide into a small bowl and either dip the stain area into the liquid or use your trusty old toothbrush to work the liquid into the stain.

2. Lemon Juice

The acid in lemon can break down stains on your underwear. If you've got a lemon lying around, cut it in half. Then rub the lemon over the bloodstain. 

Continue until you see the stain has disappeared. You may have to repeat this process a few times for the stain to fully disappear. Finish by washing your undies in cool or cold water.

3. Salt

Salt is another great household stain-buster. You can quite literally use the salt you sprinkle on your dinner! Just mix one part salt and two parts cold water. Gently apply the salt mix to the stain and watch it disappear... Rinse the fabric well when you're done.

4. Baking Soda

Similar to salt, you can also make a paste from cold water and baking soda (yes, the kind you put in your fridge or freezer to deodorize it). Mix water and baking soda to form a paste and apply to the stain area. Again, always rinse well once you're done. Repeat if you don't get it all!

Wanna Get Even Weirder?

This might be getting a little weird... but there are even wackier ways to get those stains out of your undies. Feel like experimenting? Try these: 

5. Aspirin

Follow the same method as with the salt or baking soda: Just crush a few aspirin and mix with water to form a paste. Apply it to the stain and you should see it start to budge.

6. Unseasoned Meat Tenderizer

Okay, this one is truly out there. Meat tenderizer is a blend of salt and bromelain used to tenderize... you guessed it... meat. That combo of ingredients also makes it a great stain remover.

Use the same method as before: Form a paste out of the tenderizer and water. Watch the meat tenderizer do its job. Rinse with plenty of cold water.

Skip the Dryer This Time

Just like hot water, the hot air in your dryer can cause any remaining blood stain to “set”. So, don’t toss your underwear in the dryer until you’re sure the period blood is fully removed.

Instead, you can hang the underwear to air dry. If you notice period stains still visible as your underwear dries, repeat the cleaning process again!

Get Period Blood out of Underwear: Older Blood Stains

You can follow us through the same steps for older stains. But you might want to allow even more time. Start by soaking your undies in cold water for a few hours (even overnight).

Then use any of the treatments listed above to see if it will shift that stain. There are no guarantees when you're working with older stains. A lot will depend on the fabric. But if you have a favorite pair of undies, definitely give it a try.

Again, remember: Cold water is your friend. Don't be tempted by hot water or aggressive washing cycles. You might have to repeat steps and it might take more than one round of washing to completely remove an older stain.
