My vague understanding is wash in COLD water first to avoid setting the stain.

Stand by for more authoritative voices than mine...

I always had good results with hydrogen peroxide if the stain wasn't set in by the dryer.

Oh cool, Iíll see if I can keep that in mind

Thank you so much Dadoes iíll definitely be trying WD-40 before we take it to the laundromat in 30 minutes do I just spray it on throw it in the wash on cold with normal detergent and then it should come out? Or do I need to spray WD-40 on and try to blot the stain out?

Hydrogen peroxide is the best and most tried and true method to remove blood stains. Spray on let foam up for a few minutes. Spray on again and wash in cool water with an enzyme-based detergent.

Hydrogen peroxide


If you do it first.

Warm water and detergents could likely set the stain. Don't ask me how I know.

There is a thread on this subject from a few months ago.

Pre-soak with an enzyme product in lukewarm or warm water should shift blood stains. Final treatment by washing with some sort of bleach (chlorine or oxygen) should shift any remaining traces.

Detergent will not "set" blood stains. In fact you want something that creates alkaline pH in water to shift blood. This is why people use ammonia to shift blood, which is nothing more than ammonium hydroxide gas (quite alkaline) suspended in water.

Water that is too cold will congeal blood making it difficult to shift. Temps between 86 to about 100 degrees F are fine for rinsing out or pretreating blood. Modern enzyme laundry products also work best in this range so there you are then.

Do let us know OP how you got on. If stains weren't totally removed do not put things into dryer at any cost. That would likely set blood marks making them permanent.

Good news everyone

After soaking The blanket and bedding in warm water with the Oxy cleaned and bio that, there wasnít anything and since we also had a doona with a bit of blood on it we also took that to that same laundromat, and the lady there gave me a bottle of some sort of cleaner bleach detergent whatchamacallit and showed me to squirt the blood with it then put it in the machine and let it soak for 10 minutes before starting in the machine and It was completely gone, I donít know what the hell she used so Iím gonna go back there and ask because Iíve got some actual dogs bedding with blood on it and we wonít be able to go to the laundromat until Saturday (today is Wednesday afternoon)And for a point of reference that you know was white so she probably might have used bleach but I honestly do not know, although that laundromat that I went to actually says that you canít wash pet bedding and stuff like that at their Establishment but Iíll at least ask them for advice, And it had a light sand to it that smelt like a well maintained pool so Marvin actually been a very small amount of bleach I genuinely donít know

"Lizze Borden failed miserably at removing blood stains"

Truth to tell it is nearly impossible to remove all traces of blood stains from fabrics and many other bits.

You can decolorize and break apart good part of stain so it isn't visible to naked eye. But treating area with certain substances like luminol will show remnants.

Blood marks along with those caused by other bodily fluids will show when viewed under black light.

Many better "French" or other laundries examine items under black light as part of sorting to examine for marks and soils that will need pre-treatment or other care.

Other thing of course is something that comes to most of us; after washing and things are dried where stain once was is a shadow.

There are two ways of removing blood.

Enzymes will digest much of it, leaving remaining traces to be bleached out.

Or use of alkaline pH will break down good amount of blood (good helping of solvents will help), helping to remove it from fabrics. Again final traces can be removed by bleaching.

Laundries in UK doing hospital work until rather recently used nothing more than built soap, sodium metasilicate and oxygen bleach.

"and the lady there gave me a bottle of some sort of cleaner bleach detergent whatchamacallit and showed me to squirt the blood with it then put it in the machine and let it soak for 10 minutes before starting in the machine and It was completely gone..."

You don't need anything fancy; just any top shelf spot remover like Shout or Zout, or liquid detergent such as Tide, Persil, etc...

Apply bit of stain remover to blood mark and work into stain as directed. Wait given recommended time, then apply hydrogen peroxide that comes in brown bottles from chemists. Wait a bit again, then launder as usual. Works every time!

Keep a bottle of Ecolab "protein" spot remover or Spray and Wash stain stick near hamper. When something has blood stain hit it with a bit of either, then bung it into hamper. On wash day things go into machine and blood is gone.

What laundry attendant likely offered was a packaged spot remover that contains hydrogen peroxide and solvents. It couldn't have enzymes as the peroxide will kill them off making product not shelf stable. There are "dual action" products that have enzymes and hydrogen peroxide, but these are in two separate containers joined as one bottle. When you squeeze or pour things out the two mix....

How people choose to deal with blood marks normally comes down to how much of it there is on wash day. Spot treatment works well for one or maybe a few items, but if you've got an entire load (such as healthcare, mortician, cleaning up after a horrible accident, etc...), in wash treatment is way to go.

Take it from an old nurse from back in the days of white uniforms....hydrogen peroxide first!  Works every time, for me at least.  Put it on, let it boil.  Work a little with a toothbrush or something, add a little more, repeat until it's gone.  Glad we don't have to wear white uniforms anymore.

, Iíll be keeping that in mind if I end up getting any

Blood on anything, as I do you have white sheets and mostly other white bedding, so that means I could make use of that
