How To Get Blood Stains Out Of Carpet

Just a small papercut or similar injury can cause a few blood droplets to land on the surface of a beautiful, new carpet, probably on the most visible spot.

Because blood stains settle very quickly between the carpet fibers, so treating them effectively when accidents occur is rather difficult. After all, the appropriate care of the injured person or pet is an absolute priority, often leading to the need to clean dried blood stains.

Also, be very careful when cleaning somebody else's blood - always ensure self-protection when handling somebody else's blood. For example, wear protective gloves to protect yourself from potentially transmissible diseases!

How To Clean Blood Stains - Intro

Blood stains, just like red wine and/or coffee stains, are some of the most difficult stains to remove completely, but it can be done. There are various methods for removing fresh and dried blood stains from carpets and even clothes that have been successfully tried and tested.

This article will give You a detailed collection of tips on removing blood stains from carpets, upholstery, clothes, rugs, and similar surfaces.

One of the most important things when trying to remove the blood stains is to start as soon as possible, while the blood is still fresh and it didn't have time to settle and dry out among the carpet fibers.

Also, regardless if You are cleaning sensitive carpets or some tough rugs, always start with the gentlest approach: cleaning with plain, cold water.

Note: if You must help the injured person or pet, pour some cold water over the blood stain to prevent it from drying quickly.

If cleaning with cold water is unsuccessful,  only then reach for gradually more aggressive cleaning methods.

Regardless of whether You are using only clear water or mixing it with some cleaning agent, You should always use cold water - blood is water-soluble, and cleaning it with warm or even hot water may sound a good option.

But, when it is hot, the protein building blocks in the blood coagulate, making the blood stains much more difficult to remove.


How To Remove Blood Stains From Carpets With Clear Cold Water

This is very important and has to be repeated again: use cold water!

Hot or warm water can permanently cause blood stains to stick to the carpet due to the coagulation of blood proteins.

The cleaning procedure is actually very simple:

Spray the cold water on the affected area or soak a white, clean cloth with cold water and place it on the affected area.

To prevent blood from spreading on the clean areas, always work your way from the outside to the center of the blood stain.

Using a clean, dry cloth or even a wet/dry vacuum, moisture (a mix of water and blood) can be picked up from the carpet - personally, clean, dry cloths give the user more control over rubbing motion and cleaned depth.

Repeat wetting and then drying until the blood stain is finally removed. And when the blood stain is removed, dry the carpet - using a hair dryer, You can finally dry your carpet completely faster.

Clear, cold water is a surprisingly efficient method for removing dried or fresh blood stains, but if this method does not lead to the desired success, other, more aggressive methods must be used.

Just to be sure, before cleaning blood out of carpets, be sure to test the solvents/detergents first on some invisible areas of the carpet so that You can be sure that it does not discolor the carpet in any way or cause some other form of damage.

Also, carpets placed on sensitive floors should be cleaned using minimum amounts of water/cleaning solution to prevent any damage on the floor itself.


How To Remove Blood Stains From Carpets With Dishwashing Detergent and Water

A mix of dishwashing detergent and cold water is an excellent aid in removing deeply embedded blood stains, even the dried ones.

Mix 1 (one) tablespoon of dishwashing liquid detergent with two cups of cold water.

Put the liquid on a clean, white cloth and treat/blot the blood stains from outside toward the center of the stains.

If the blood has dried out and the cloth is not removing the blood stain quickly enough, take a toothbrush or similar soft brush (or even a sponge) and clean/rub the stain while avoiding scrubbing too hard, though - too strong rubbing may spread the stain even more or deeper into the carpet.

To rinse the cleaning liquid out of the carpet, clean the affected area several times with a damp (cold water only!), clean cloth.

If the dirty area is larger or the stain is fully dry, You may need to repeat the entire procedure several times.

Afterward, place something heavy on another new dry towel to absorb the moisture better, or just press it with your own palms.

Using a hair dryer, You can dry the carpet completely and much faster, but note that not all carpets tolerate the heat that hair dryers can produce.


How To Remove Blood Stains From Carpets Using Vinegar

To use vinegar to clean the carpet, make a 50:50 mix of cold water and white vinegar in a spray bottle and apply the mix to the blood stains.

Now, using a dry and clean cloth (or even a gentle brush), gently rub the liquid into the carpet, trying not to spread the blood even more.

After that, press the dry cloth or paper towel on the cleaned area and remove as much liquid as possible.

If required, repeat the procedure until the carpet is clean.

Note: vinegar is a natural remedy, and not only that its acetic acid dissolves the dirt, but it also helps the faded colors of the carpet to shine again.


How To Remove Blood Stains From Carpets With A Baking Soda And Water Paste

Take a small bowl or cup, fill it with cold water, and add baking soda until the mix reaches the consistency of a thin paste.

Note: it is very important to use cold water. But, carbonated mineral water is also suitable for this purpose since it helps remove the deeply embedded blood from the carpet - as the CO2 bubbles are created, they help remove blood from the carpet fibers.

How To Remove Blood Stains From Carpets With Ammonia And Water

Note: Ammonia is dangerous - in any case, avoid the possibility of the ammonia getting into your exes, mouth, nose, or respiratory tract! Also,  never mix it with bleaching agents containing chlorine since very dangerous vapors may result from a resulting reaction.

Before using ammonia, read the labels on the product and act according to their instructions, especially safety measures.

Note: Ammonia should never be used on wool carpets because it is very alkaline. Before using ammonia to clean the carpet, check if the carpet is allowed to be cleaned using ammonia.

Mix 1 tablespoon of ammonia with half a cup of cold water (roughly 1:8 ratio) in a spray bottle and apply this solution to the blood stains - leave it for about 5 minutes.

After that, clean the blood stains by pressing the stains using a white cloth - press gently, but never scrub or rub!

Rinse the area thoroughly with plain water and a cloth (or even paper towels).

Then, to remove as much water as possible and speed up the drying process, place something heavy on another dry towel so the moisture can be absorbed better. Let this sit for a few minutes.

Using a hair dryer (if the carpet tolerates such heat), You can finally dry your carpet completely faster.


How To Remove Blood Stains From Carpets Using Hydrogen Peroxide

Note: Hydrogen Peroxide (H2O2) is a very strong oxidizer. It should be considered only as a last resort when trying to remove the blood and other stains from carpets and other surfaces - by doing so, you risk lightening the carpet's color as a result of the application. It is that strong.

The actual procedure is very simple.

Apply 3% hydrogen peroxide to the blood stains and let the solution settle down for 60 minutes.

After that, press the clean cloth on the stain several times until the stains are completely gone.

When cleaning with Hydrogen Peroxide, there is really no need to rinse the surface, but just in case, feel free to add some cold water to the surface and finish the cleaning as if You are cleaning just with plain, cold water.

If necessary, dry the carpet using a dry cloth or paper towels, followed by a hair dryer (if the carpet supports such drying).


How To Remove Blood Stains From Carpets Using Portable Spot Cleaners and Carpet Washers

Personally, Carpet Spot Cleaners and carpet washers (carpet cleaners, carpet shampooers, etc.) are the best cleaning aids in removing blood and other stains from carpets, upholstery, area rugs, and similar surfaces.

And should be used if available immediately if removing the blood stains with plain cold water and perhaps with dishwashing detergent didn't work.

The procedure is very simple - read the labels and act accordingly, but generally, You should:

  • Apply the suitable pretreat spray (if available) to dirty areas.
  • Fill the carpet spot cleaner or carpet washer with clean water and cleaning solution.

Most carpet spot cleaners and carpet washers don't have water heaters but allow the user to fill the clean water tank with warm (warm, not hot) water - in either case, fill the cold water, and if the water heater is present, keep it turned off.

  • Apply the cleaning solution/clean water to the dirty area, gently brush the surface from outside toward the center of blood stains and remove as much dirt liquid as possible.
  • If required, repeat the process once more.
  • Let the carpet air dry or use a hair dryer (if the carpet is not too sensitive) to dry the carpet completely.

And that would be all, blood stains are removed, and the carpet is clean again.


Few Final Words

Blood, coffee, red wine, and similar stains can sometimes be hard to clean. But, the sooner your start with the cleaning process, the better.

While common cold water can help the user completely remove the blood stains from the carpet, having a pretreat spray and a carpet cleaning solution for manual or mechanized cleaning can be a great help.

And whatever You do, stay safe, especially if it is not your blood - some cleaning solutions are far from being safe, so use them according to the instructions.
