How to remove blood stains out of carpet

Lately, I have been called out to quite a few jobs where I have been asked how to get blood stains out of carpet. Now don’t get me wrong, they were not gruesome murder scenes or anything like what you see on TV. They were just your everyday, run of the mill nose bleed type situations and one  unexpected home birth! If you have pets or children, you will be very familiar with the types of accidents that result in blood staining your carpet. There is however no need to panic. Blood is tricky, but can be removed provided you follow the right steps.

How to get blood stain outIt can be difficult to get blood stains out of carpet

This is because, hemoglobin binds to the carpet fibres once it comes into contact with oxygen. The sooner you can attend to the stain, the better. Wet blood can be removed much more easily than blood that has been allowed to dry and bind firmly to the carpet fibres.

I always recommend using a professional carpet cleaner to remove dried blood stains from carpet. The protein and enzyme spotters required to shift dried blood from carpet, can be hazardous, especially if you are nor familiar with the correct safety procedures.  Some, like ammonia can cause respiratory issues and should be used with extreme caution.  Always use in a well ventilated space, followed by thorough rinsing.

Then there is also the possible bacteria and pathogens which needs to be considered. Any anti microbial treatments used to sanitise your carpet, must be colour safe.  Some contain bleach which will remove the colour from your carpet fibre and may cause more damage. Always wear disposable gloves when trying to get blood stains out of carpet.

The following is the first step I recommend to get blood stains out of carpet; Blood stain on carpet

  1. Cold Water:

    The first step is to dilute the blood as much as possible. The best way to do this is by filling a spray bottle with cold water and misting the water over the stain. It is very important to use cold water as hot/warm water can set the stain permanently into the carpet fibres.

  2. Blot Gently:

    Take a clean dry cloth or towel and gently blot the stain.  Do not rub or you may damage the carpet fibre and actually push the blood further down into the fibres and carpet backing.  As the blood transfers onto the cloth, fold it over so a fresh, clean piece of the cloth is in contact with the stain. Repeat, alternating the water spray and dabbing for as long as there is colour transfer onto the cloth.

  3. Dry:

    The stain should now be much lighter in colour, if not completely removed. If you managed to get the blood stains out of carpet, dry the area as much as you can by using clean dry towels or even a wet dry vacuum if you have one.  A small fan placed next to the stain will also help dry the area.  Alternatively, you can place a dry towel over the spot and put something heavy like a glass or book on top. Leave it overnight to help the towel absorb the water. Once the area is dry, vacuum the carpet to restore the natural look of the carpet nap.

What to try next….

Sometimes blood stains need a bit more of a push before they give up their hold on your carpet fibres.  If you find you are left with a light stain after diluting the blood with the method above, you can try something a bit stronger, depending on the type of carpet you have. Or you can call in a professional like Black Gold Carpet Cleaning. We have all the right chemicals, equipment and training to make sure you get the best result possible without any mess or fuss. We can usually get blood stains out of carpet without too much trouble.

 Additional treatments to remove blood from synthetic and woolen carpets

Synthetic carpets

can be spot treated with ammonia, which is a very good staihow to get blood stain out of carpetn remover and a good choice when you want to get blood out of carpet.  As previously mentioned ammonia produces strong fumes which can cause breathing difficulties. Always use caution, read the label, use in a well ventilated space and rinse thoroughly.  Ammonia should also be avoided if you have pets (especially cats) as the smell of ammonia can cause them to urinate on the carpet.

Mix a table spoon of ammonia with a cup of cold water in spray bottle and mist over the stain.  Then gently dab with a clean dry cloth.  Repeat until stain has been removed.  Then rinse the area thoroughly with cold water and dry with a clean dry cloth.  You can put a dry towel over the wet area and place something heavy like a glass or book on top to help the towel absorb the moisture, and leave for several hours or over night.


Woolen Carpets

blood stains on carpet

can be damaged by ammonia so we do not recommend you use any spotters containing ammonia on woolen carpet.  Instead you can try, mixing 1 teaspoon of clear dish washing liquid with 2 cups of cold water in spray bottle and misting over the stain.  Then either dab with a clean dry towel or gently agitate with an old toothbrush.  Do not rub or apply too much pressure or you may damage the carpet fibres and push the blood down further into the carpet backing & underlay.  Rinse off thoroughly with a damp clean cloth. Repeat if necessary, and dry with a clean dry towel. A fan placed next to the area will also help speed up the drying process.

Thanks Julia, you are right, blood can been very difficult to remove, especially once it dries. I usually always recommend getting a professional carpet cleaner in to remove blood, but if it is just a few drops and hasn’t been there very long, then there are steps that can be taken to remove the blood successfully without getting professional help. I completely understand that budgets are tight so I always try to give advice so people can do it themselves, but only when appropriate. I always recommend seeking professional advice before tackling any stain!

If the blood stain you’re trying to remove is dry, go ahead and brush it with a steel brush to loosen the stain. Thanks for the informative post.

Thanks for your comment Aussie Carpet. It is true – a steel brush will probably loosen the dried blood but it will also damage the carpet fibres so I would probably not recommend such an abrasive process.
