How to get period blood out of underwear

You’ve probably heard that menstrual blood stains clothes and underpants. And you might even know that some women wear pads or tampons during their periods. But did you know that these feminine hygiene products also cause stains on clothing? Learn how to prevent them from happening.

Menstrual blood is red because it contains hemoglobin, which gives blood its color. When you menstruate, your body releases a certain amount of blood into your uterus each month. This blood mixes with other fluids, such as water and mucus, and forms a thick mixture called menses. The menses then flows through the vagina and cervix before leaving the body via urination. If you don’t want to stain your clothes, you should wash your undies regularly.

To remove menstrual blood from your undergarments, try using a mild soap solution. Simply mix equal parts of warm water and liquid dishwashing detergent together. Then soak your underclothes in this solution overnight. Afterward, rinse the stained items thoroughly and hang them to dry.

Dealing with period stains on underwear can be a common concern for many women. However, there are effective methods to remove period blood stains and restore the cleanliness of your underwear. In this article, we will explore various techniques to get period blood out of underwear, ensuring that you can handle this situation with ease.

Rinse the Stain with Icy Cold Water

When you notice a fresh period blood stain on your underwear, the first step is to act quickly. Rinse the stained area with icy cold water. The cold temperature helps prevent the blood from setting into the fabric, making it easier to remove. Gently rub the stained area under the running water to loosen the blood particles.

Allow the Underwear to Soak Overnight

If the stain persists after the initial rinsing, it’s best to let the underwear soak overnight. Fill a basin or sink with cold water and add a small amount of mild detergent. Submerge the stained underwear in the soapy water and leave it to soak overnight. This soaking process helps to break down the stubborn stain and prepare it for further treatment.

Treat Any Remaining Stain with a Stain Remover

After the soaking process, check the stained area for any remaining discoloration. If necessary, you can apply a stain remover to tackle the stubborn stain. There are several options you can try:

  • Detergent: Apply a small amount of liquid detergent directly to the stain. Gently rub the fabric together to work the detergent into the fibers. Let it sit for a few minutes before rinsing with cold water.
  • Lemon Juice: Squeeze half a lemon and rub it over the stain. The citric acid in lemon juice helps to break down the blood particles. Massage the lemon juice into the fabric and let it sit for a few minutes before rinsing with cold water.
  • Hydrogen Peroxide: Apply a small amount of hydrogen peroxide to the stained area. Allow it to sit for a few minutes, then rinse with cold water. Be cautious when using hydrogen peroxide on colored fabrics, as it may cause discoloration.
  • Liquid Clorox2: Follow the instructions on the Clorox2 bottle and apply the stain remover directly to the stain. Allow it to sit for the recommended time, then rinse with cold water.

Rub Half a Lemon over the Stain and Massage It Out

For particularly stubborn period blood stains, you can try using a fresh lemon to further break down the discoloration. Cut a lemon in half and rub it directly over the stain. The natural acids in lemon juice can help dissolve the blood particles. Massage the lemon juice into the fabric using gentle circular motions. Rinse with cold water.

Use Gentle Stain Removers

In addition to the aforementioned methods, there are several commercial stain removers available on the market specifically designed to tackle tough stains, including period blood stains. Choose a gentle stain remover that is suitable for your fabric and follow the instructions provided. Apply the stain remover to the affected area and allow it to work its magic before rinsing thoroughly.

Use Bleach on White Underwear (Only!) and Be Sure to Wash Thoroughly Before Wearing

If you have white underwear and the stain persists, you can consider using bleach. However, it is crucial to note that bleach should only be used on white fabrics to avoid discoloration. Follow the instructions on the bleach bottle and dilute it according to the recommended ratio. Apply the diluted bleach to the stain, ensuring it covers the affected area completely. Let it sit for a few minutes, then rinse thoroughly with cold water. Wash the underwear as usual to remove any residual bleach before wearing.

Make a Paste of Baking Soda and Water and Apply It to the Stain

Baking soda is known for its stain-removing properties and can be an effective solution for period blood stains. Create a paste by mixing two parts baking soda with one part water. Apply the paste to the stain, making sure it covers the affected area. Let it sit for anything between 30 minutes to overnight, depending on the severity of the stain. Rinse the underwear with cold water and check for any remaining discoloration.

Try Gently Using Your Nails or an Old Soft Toothbrush to Rub the Area

For tougher stains, you can use a gentle physical agitation method to help remove the blood particles. Take your nails or an old soft toothbrush and gently rub the area where the blood is set on your underwear. Be careful not to scrub too vigorously to avoid damaging the fabric. The gentle rubbing motion can help loosen the stain and facilitate its removal.

Wash and Dry Your Underwear as Usual

After following any of the methods mentioned above, it is essential to wash and dry your underwear as usual. Use cold water and a mild detergent to wash the garment. Check the stained area before putting it in the dryer to ensure the stain has been successfully removed. If any discoloration remains, repeat the stain removal process or try an alternative method.

Act Quickly for Better Results

It’s important to remember that acting quickly is key when it comes to removing period blood stains. The fresher the blood stain, the easier it is to get out. As soon as you notice a stain, take immediate action by rinsing it with cold water and following the appropriate stain removal techniques. Prompt action increases the chances of successful stain removal.
