How To Get Period Blood Out Of Your Underwear

How To Get Period Blood Out Of Underwear

You’ll be pleased to know that it really is possible to get blood out of your underwear - here are WUKA’s top tips on how to get period blood out of underwear:

How to wash fresh blood out of underwear

We’ve all been there- our period arrives a day or two early, and that’s another perfectly good pair of knickers ruined. But before you throw them away and add to our ever growing problem of overflowing landfill, stop! Period blood stains can be removed, and quite easily too. Just follow our four golden rules:

1. Don’t leave the blood to set

Treating the stain as quickly as possible is vital, because if it’s left too long the proteins in the blood will ‘set’, making it so much harder to treat. If you can, follow the next three steps as quickly as possible. 

2.Rinse with cold water

Rinsing the stain with cold water will help to lift as much of the blood from the fabric as possible. And yes, it needs to be COLD water. Hot water will help the stain to really set in, even if you get to it quickly. So rinse, quickly, and make sure the water is cold. 

3.Treat the stain

Once you’ve rinsed, you need to treat the stain. Gently use your finger tips or an old toothbrush on the stain, working in a lifting motion, again in cold water.

4.Wash and dry as usual

After treating the stain, wash your underwear as normal. We recommend WUKA period pants are washed in a cool wash, 30-40 degrees, although we prefer 30 as it’s better for the environment. Air dry outdoors on inside on an airer. No tumble drying!

Sometimes it’s not possible to treat a blood stain straight away, or the first wash might not get it all out. But you still don’t need to throw them away! 

If you can, soak the garment in cold water for as long as possible. This will help to lift the stain. Then try one of these natural remedies to treat the stain:

  • Baking powder- mix one part baking powder with two parts cold water in a bowl. Use a cloth to dab the mixture onto the stain and leave on for at least an hour, or overnight if you can. Then wipe away the residue and wash as normal.
  • Fresh lemon juice- Just squeeze the juice from half a lemon directly onto the stain and leave for five minutes. Then gently rub at the stain, rinse and wash as normal.
  • White vinegar- either mix a small amount of white vinegar with a small amount of washing detergent, or just use the vinegar neat. Pour it onto the stain and let it soak for at least ten minutes, or overnight if you can. Gently rub the stain with a dishcloth then wash as normal.

After treating, wash and dry as normal. Repeat the whole process if necessary, until the stain is removed. 

Use period pants to absorb your flow

Tired of leaking period blood onto your normal underwear when using sanitary pads and tampons? Switch to period pants! 

Period pants are made to bleed into, a complete pad and tampon replacement- and there’s no need to double up on heavy days either. Choose your style, choose your flow and wear them like normal pants. 

The super absorbent gusset with absorb your period flow, locking it away from the body in the middle layers. This leaves you fresh and comfortable, allowing air to circulate so that infections and smells are kept at bay.

And because period pants are made to absorb blood, there’s no need to worry about period blood stains either.

How to wash period pants

Period pants need some TLC to keep them fresh and clean, but there’s not too much to it. If you have time, you can wash by hand (period pants love this!) but it’s not crucial. 

Just rinse in cold water, gently squeezing to remove as much excess blood as you can, and then wash in the machine with your normal load. Wash at 30 degrees, with no fabric conditioner, and then air dry. We recommend using a wash bag to keep your pants protected in the wash.


How to freshen up period pants

Period pants are made to absorb your flow, and rinsing before washing helps to remove excess blood, keeping them nice and fresh and ready to wear again and again. That said, period pants can sometimes start to smell a little if blood is left to soak for too long. This is normal and easily remedied. 

Just mix one part white vinegar with three parts water (just enough to cover your underwear) and soak for 20 minutes. Then wash. If you want to add more vinegar to your machine you can, and this will also help to fight off any odour that might have occurred. You can also add a few drops of essential oil to your machine- lavender is great for calming and soothing.
