let's be real: most laundry stain removers are useless when it comes to period blood.
the short version: rinse in cold water, treat with an enzyme remover, never use hot water or bleach, then wash on a cool cycle. here's the full method, for fresh leaks and stains that have been sitting in the laundry basket for days.
you wake up to a surprise leak on your favourite pair of knickers, run to the sink, and scrub the fabric with whatever stain remover is under the bathroom cabinet. you put it through the wash, cross your fingers, and pull it out… only to find a stubborn, faded brown shadow set permanently into your underwear.
you did everything right, but because the product failed, that pair is headed straight for the bin. leaks are natural. binning your favourite underwear because of a stain shouldn't be.
why bleach and hot water are ruining your clothes
when a leak happens, the instinct is to reach for hot water. but blood is a protein, and heat causes proteins to set. hot water bonds the blood directly into the fabric's fibres, making the stain permanent.
or worse, you reach for bleach, especially on white underwear. but bleach physically weakens natural fibres over time. instead of looking pristine, your whites are left with a brittle, yellowed chemical ring. you don't need harsh chemicals to save your clothes, you need an approach built for the protein in blood.
that's where out for blood comes in. because period blood is a protein, our enzyme formula breaks the stain down at a microscopic level rather than bleaching it out lifting the mess while leaving your fabric, and your skin, untouched. it works on cotton, denim, synthetics and blends (just keep it away from silk and wool).
simple steps to rescue your underwear
- prep - always start with cold water. rinse the stained area under a cold tap to wash away the surface excess, then wring out the fabric until it's just damp.
- treat - apply the out for blood formula generously to both the front and the back of the stain. using your fabric brush, gently work it into the fibres for one minute on each side.
-
wait - let the formula do the heavy lifting:
- fresh stains (under 24 hrs): fold a clean part of the fabric over the stain so it doesn't dry out, and let it sit for 30 minutes.
- set stains (24+ hrs): if it's been sitting in your laundry basket for a few days, place the underwear in a closed, waterproof container (like a ziplock bag) to keep it moist, pour a little extra formula over the stain, and let it soak for 2 hours.
- wash - machine wash as normal on a cool cycle (30°C), let it dry, and you're good to go.
stop throwing your underwear in the bin
a stain shouldn't dictate your wardrobe, and it certainly shouldn't cost you in replacement underwear. keeping a bottle of out for blood at home means you can reclaim your peace of mind and keep your favourite pieces in rotation for longer.

frequently asked questions
can you get dried or old period stains out of underwear?
yes. set-in stains are tougher because the blood has bonded to the fibres, but they're far from hopeless. the trick is to keep the stain moist and give an enzyme treatment longer to work (see the "set stains" step above), rather than scrubbing harder.
does period blood come out of underwear in a normal wash?
often not on its own, especially once a stain has dried. a normal cycle, particularly a warm one, can actually set the stain. treat the stain before it goes in the machine, and always wash on cold.
how do you get period stains out of white underwear without bleach?
you don't need bleach and you shouldn't use it, as it weakens and yellows the fabric. cold water plus an enzyme remover lifts the stain while keeping whites intact.
