What You’ll Need

Hydrogen Peroxide

Hydrogen peroxide is a great solution to have around the house for various types of stains, but especially for blood stains.

Laundry Detergent

A mild laundry detergent will be necessary to soak the stain and ensure that it does not get set into the fabric. 

Clean Rag

A clean rag will be used in various steps in the process, so it will be a good idea to have a couple on hand to ensure full removal of the blood stains.

I have found that these microfiber cleaning cloths work best.


Gloves should always be worn when working with blood, especially if you are cleaning someone else’s blood out of clothing.

Step by Step Instructions For How To Remove Blood Stains From Underwear

#1. Dab The Stain With Cold Water. 

As soon as possible, dab the stain with cold water.

If the stain is fresh, you should remove a good amount of the blood by dabbing it with water.

If the stain is older or dried, you will not be able to remove much by dabbing it with water, but you will still be able to lift some of the excess blood off of the stain before moving on to the next step. 

Pro Tip:

Do not scrub the stain!

This will only push the blood down into the clothing’s fibers and make it much harder to remove. 

#2. Soak The Underwear 

Fill a sink or other basin with cool or room temperature water and mix in a small amount of mild laundry detergent.

Let the clothing soak for up to 6 hours.

Do not use bleach, as letting the fabric soak in bleach can seriously damage the fabric’s fibers.

Be careful of fabrics such as wool or silk, as these may not react well to being soaked for long periods. 

#3. Blot The Fabric With Hydrogen Peroxide

After the stain has soaked for several hours, use a small amount of hydrogen peroxide to blot the stain until it is completely removed.

Hydrogen peroxide in small amounts will not cause damage to the fabric or your skin, so it is much safer to use than bleach.

Blot the stain a few times with the microfiber cleaning cloth to make sure the stain is completely removed.

Make sure to rinse the fabric well after using hydrogen peroxide on it. 

#4. Dry The Fabric

Hang the underwear or clothing up to dry to ensure that the stain is completely removed.

Do not put it in the dryer, as this will only force the stain further into the fabric.

Once the fabric is completely dry, you will be able to tell if the stain has been removed or if it is still lingering.

If the stain is not completely removed, repeat these steps as many times as necessary.

If the stain has been removed effectively, you can wash and dry the clothing like normal. 

Commonly Asked Questions

Can I soak the underwear in hot water? 

While it may not make much sense to soak the underwear in cool water, hot water can cause the stain to get further set into the fabric.

Cool water will help lift the stain from the fabric and get your clothing cleaner much faster and easier.

I already ran my blood-stained clothing through the washer and dryer. Will I be able to remove the stain? 

Clothing washed and dried with a blood stain can still be saved, though it will be much harder to remove.

Hydrogen peroxide should remove all of the stain, but you may need to repeat the process a few times before the stain is completely removed. 

Can I scrub the stain with a toothbrush? 

You should not scrub the stain at all until it has been soaked in detergent and cool water.

After the detergent has been rinsed out and you start to use the hydrogen peroxide, you can use a toothbrush to scrub it.

However, when you scrub the stain, you run the risk of setting the stain further into the fabric.

If the stain is already mostly removed and you are using hydrogen peroxide to get the last remaining bits, a toothbrush would be a great tool to use.
