Why Is Blood Hard to Remove from Carpet?

Before we dive into the specifics of removing blood from your carpet, it’s important to understand why this task can be so challenging. Blood contains a variety of compounds that make it difficult to clean, including:

  • Proteins: Blood is rich in proteins, which can bind to the carpet fibres and cause the stain to set in quickly. These proteins essentially “glue” the blood to the carpet, making it harder to lift out.
  • Hemoglobin: Hemoglobin is the iron-rich compound in the blood that gives it its distinctive red colour. This pigment can also adhere to the carpet, creating a stubborn stain.
  • Coagulants: Blood naturally contains coagulants that help it to clot and stop bleeding. These same coagulants can cause the blood to dry and harden, making it even harder to remove once it’s set in.

The sooner you can address a blood stain, the better. The longer it has to soak into the carpet fibres and dry, the more difficult it will be to fully remove. That’s why it’s crucial to act quickly when dealing with a blood spill on your carpet.

Supplies Needed for Removing Blood from Carpet

Before you begin the cleaning process, make sure you have the following supplies on hand:

  • Clean, white absorbent cloths or paper towels
  • Cold water
  • Mild dish soap or carpet cleaner
  • Hydrogen peroxide or enzymatic cleaner
  • Baking soda
  • Stiff-bristle brush
  • Vacuum cleaner

Having these items readily available will make the cleaning process much smoother and more effective. Let’s dive into the step-by-step instructions for removing blood from your carpet.

Step-by-Step Guide for Removing Blood from Carpet

Step 1: Blot the Stain Immediately

As soon as you notice the blood spill, spring into action. The key first step is to blot the stain with a clean, white cloth or paper towel. Avoid rubbing the stain, as this can push the blood deeper into the carpet fibres.

Gently blot the area, working from the outside of the stain towards the centre. Continue blotting until you’ve absorbed as much of the blood as possible.

It’s important to work quickly, as the longer the blood sits, the harder it will be to remove later on.

Step 2: Treat the Stain with Cold Water

Once you’ve blotted up as much of the blood as possible, it’s time to start the cleaning process. Start by flushing the area with cold water. Avoid using hot water, as this can set the stain.

Carefully pour or spray the cold water directly onto the stained area, allowing it to soak in for a minute or two. Blot the area with clean cloths or paper towels to absorb the diluted blood.

Repeat this cold water treatment a few times until the water runs clear and you’ve removed as much of the stain as possible.

Step 3: Apply a Cleaning Solution

If the cold water alone isn’t doing the trick, it’s time to bring in a cleaning solution. You can use a mild dish soap or a dedicated carpet cleaner for this step.

Make a solution of warm water and a small amount of dish soap or carpet cleaner. Dip a clean cloth or sponge into the solution and gently blot or dab it onto the stain. Avoid scrubbing, as this can spread the stain or damage the carpet fibres.

Let the cleaning solution sit on the stain for a few minutes to allow it to penetrate and start breaking down the blood compounds.

Step 4: Rinse and Blot Again

After allowing the cleaning solution to work its magic, it’s time to rinse the area again with cold water. Carefully pour or spray the water directly onto the stained spot, then blot it up with clean, absorbent cloths or paper towels.

Repeat this rinsing and blotting process until the water runs clear and you’ve removed as much of the stain as possible.

Step 5: Try an Enzymatic Cleaner or Hydrogen Peroxide

For particularly stubborn blood stains, you may need to reach for a more powerful cleaning agent. Two great options are enzymatic cleaners and hydrogen peroxide.

Enzymatic cleaners are designed to break down the proteins in the blood, making it easier to lift the stain. Simply apply the cleaner according to the manufacturer’s instructions, let it sit for a few minutes, then blot and rinse.

One highly-rated enzymatic cleaner is the Biz Stain Fighter Enzymatic Cleaner. This product is specifically formulated to tackle tough protein-based stains like blood and has received excellent reviews from customers.

Hydrogen peroxide is another effective option for removing blood stains. Mix a solution of 1 part hydrogen peroxide to 1 part water, and apply it to the stain. Let it sit for 5-10 minutes before blotting and rinsing.

Be cautious when using these stronger cleaning agents, as they can potentially discolour or damage the carpet if not used properly.

Step 6: Sprinkle Baking Soda

If the blood stain is still visible after trying the above methods, you can turn to baking soda as a final step. Sprinkle a generous amount of baking soda over the stained area and let it sit for 30 minutes to an hour.

The baking soda will help absorb any remaining moisture and blood residue. Once the time is up, vacuum up the baking soda, revealing a hopefully stain-free carpet.

For an extra boost, you can also try mixing the baking soda with a small amount of hydrogen peroxide or white vinegar before applying it to the stain.

Step 7: Repeat as Needed

In some cases, it may take multiple rounds of cleaning to fully remove a stubborn blood stain. Don’t get discouraged if the stain doesn’t come out completely the first time. Simply repeat the process, using a stiff-bristle brush to agitate the carpet fibres and help lift the stain.

With patience and persistence, you should be able to get even the toughest bloodstains out of your carpet.

Prevention Tips for Future Blood Stains

Of course, the best way to deal with blood stains is to prevent them in the first place. Here are some tips to help you avoid future carpet-staining incidents:

  • Keep a well-stocked first aid kit on hand to quickly address any bleeding injuries.
  • Be extra cautious when handling raw meat or other food items that could potentially drip or spill.
  • Use area rugs or mats in high-traffic areas to protect your carpets.
  • Regularly clean and maintain your carpets to make it easier to treat any future stains.

By taking proactive steps to prevent blood stains, you can save yourself a lot of time and hassle down the road.

Another great product to have on hand for preventing and treating blood stains is the Clorox Carpet Cleaner and Deodorizer. This versatile cleaner can be used as a pre-treatment for tough stains or as a general carpet refresher to keep your floors looking their best.


Removing blood from the carpet can be a challenging task, but with the right techniques and products, it is possible. Remember to act quickly, use the right cleaning solutions, and be patient and persistent.
