Has a blood stain left you feeling frustrated? How do you get blood out of carpet without making the stain worse? Whether from an accident or a minor injury, blood stains on your carpet can seem like an impossible challenge to tackle. But don’t worry—there are effective solutions for cleaning blood stains that will help restore your carpet to its original state.
The good news is that getting blood out of the carpet is possible with the right approach. The key is to act quickly and use the right cleaning agents. Cold water is typically the first step for fresh blood stains. You can mix common household items like baking soda, hydrogen peroxide, or dish soap in more stubborn cases. In this guide, we’ll walk you through the most effective methods to easily remove blood stains from carpets.
But first, it’s important to understand the best techniques for different types of blood stains. We’ll cover both fresh and old stains and guide you through each one step by step.
Why is Blood So Hard to Remove?
Blood stains on carpets are notoriously difficult to remove because of the proteins and iron present in the blood. These components bind with carpet fibers, especially if the blood has dried, making it harder to lift from the surface. The type of carpet also plays a significant role in how well the stain can be removed. When blood seeps into fibers, it bonds tightly, and standard cleaning methods often fail to break that bond.
Why Speed is Critical?
Speed is critical in stain removal because fresh blood stains are easier to treat than dried ones. The longer blood sits on the carpet, the more it bonds with the fibers, permanently causing the stain to set in. Cleaning a fresh stain within minutes allows you to lift it from the surface without embedding too deeply into the fibers. By acting fast, you’ll have a much higher success rate in eradicating the stain.

Supplies Needed to Get Blood Out of Carpet
You don’t need a fancy toolkit to get blood out of carpet; basic household items are often enough to do the job. Here’s what you’ll need:
- Steel Brush: For gently lifting dried blood from the carpet fibers.
- Cold Water: Cold water prevents the blood from setting and helps to loosen it.
- Dishwashing Liquid: A mild detergent that helps break down proteins in blood.
- Spray Bottle: Spray water or cleaning solution directly onto the stain.
- Sponge: For blotting and gentle scrubbing.
- Rag: To absorb excess liquid.
- White Vinegar: Helps lift stains while neutralizing odors.
- Salt: Acts as an abrasive agent to lift the stain.
- Cornstarch: A natural absorbent that draws out liquid stains.
- Hydrogen Peroxide: A powerful agent that helps break down blood proteins.
These common household items will be your best friends when it comes to getting blood out of your carpet without spending a fortune on professional cleaners.
Why Cold Water Works Best?
Cold water is the best remedy for blood stains because it prevents the blood proteins from binding with the carpet fibers. Hot water can cause the stain to set, making it nearly impossible to remove. The cooler temperature helps to dilute and loosen the blood, allowing you to blot it away before it can dry and bond to the fibers. When dealing with blood, always use cold water for optimal results.

Notes on Different Carpet Materials
Different carpet fibers react uniquely to cleaning methods, so caution is important. Here’s a breakdown of how various carpet materials respond to blood stain removal:
- Wool Carpet: Wool fibers are delicate and can be easily damaged by harsh chemicals. Stick to mild solutions like water and detergent for wool carpets.
- Nylon Carpet: Nylon is durable and can handle stronger cleaning agents. For effective removal, you can use hydrogen peroxide or ammonia-based cleaners.
- Polypropylene Carpet: This synthetic fiber is resistant to stains and can handle most cleaning methods without damage. Cold water and a detergent solution work well for these carpets.
- Polyester Carpet: Polyester is sensitive to high temperatures, so avoid hot water. Cold water and a mild detergent are sufficient for cleaning polyester carpets.

5 Ways to Get Blood Out of Carpet
Depending on the severity and length of the stain, each of these methods can help you remove it.
- Use Cold Water
Blotting the stain with cold water is the first step in treating fresh blood stains. Cold water keeps the stain from setting into the fibers, giving you the best chance at complete removal. - Use Water and Detergent
If cold water alone doesn’t work, mix water with a mild detergent and apply it to the stain. This combination will help break down the proteins in the blood. After applying, blot with a cloth. - Use Water and Ammonia
For more stubborn stains, a water-ammonia mix can help. This method works because ammonia is an effective protein dissolver. Always test a small area before applying it to the entire stain. - Use Salt Paste
Salt can absorb moisture from the stain, especially if the blood is fresh. Mix salt with cold water to create a paste, then apply it directly to the stain. Allow it to sit for 10-15 minutes before blotting away. - Use Hydrogen Peroxide
Hydrogen peroxide is a powerful solution for dried blood stains. It helps break down the blood and remove it from the carpet fibers, but remember to use it carefully as it may cause discoloration on certain carpets.

How to Get Wet Blood Stains Out of Carpet?
Wet blood stains are the easiest to remove when tackled immediately. Acting fast is key to preventing blood from setting into your carpet fibers. With the right tools and patience, you can restore your carpet to its original condition without a trace of the stain.
Follow these simple steps to remove fresh blood stains:
- Wipe the Blood Stain with a Dry Paper Towel
When a blood spill occurs, the first step is to blot the stain with a dry paper towel. The goal is to absorb as much blood as possible without rubbing, which could spread the stain. Be gentle and continue blotting until the excess blood is soaked up. If you rub or scrub, you risk embedding the stain deeper into the carpet fibers, making it harder to remove. - Prepare a Carpet Stain Remover
Next, mix an effective yet gentle cleaning solution on the carpet. You can use a commercial carpet stain remover, but if you prefer a homemade solution, try mixing cold water with a few drops of dish soap. Dish soap is effective because it’s designed to break down oils, which makes it perfect for removing stains like blood. Hydrogen peroxide is also a good alternative for tough stains, but always test it on an inconspicuous area first to avoid damaging the carpet. - Dip a White Cloth in the Cleaning Solution and Wipe the Stain
Once your cleaning solution is ready, dip a clean white cloth into the solution. The key here is to use a white cloth, as colored cloths may transfer dyes onto your carpet. Gently blot the blood stain, starting from the outer edge and moving inward. This helps avoid spreading the stain. Continue blotting with the cleaning solution until the stain begins to lift. Note: Do not scrub the stain, which could damage the carpet fibers. Blotting is always the gentlest method for stain removal. - Wipe the Stain with a Dry Paper Towel
After blotting with the cleaning solution, it’s time to absorb the remaining moisture. Use a clean, dry towel or cloth to blot the treated area. Continue until the cloth or paper towel comes away clean and the stain is no longer visible. This step helps remove any excess cleaning solution and ensures the stain doesn’t return. Once you’ve absorbed the liquid, let the area air dry completely before walking on it or placing the furniture back. The faster you act, the better your chances of completely removing the blood stain from your carpet!

How to Remove Dry Blood Stains from Carpet?
Dry blood stains require more effort to remove than fresh ones, but they are not impossible to eliminate. The key is to break up the dried blood and gently lift it from the fibers. Look at a step-by-step guide to remove those tough, dried stains.
- Use a Stiff Brush to Remove the Dry Blood Stain
Before using any cleaning solutions, the first step is to loosen the dried blood physically. Use a stiff-bristled brush to scrub the blood stain gently. The goal is to break up the dried blood without damaging the carpet fibers. Start lightly brushing the affected area to remove as much dried blood as possible. Be cautious not to scrub too aggressively, as this can fray the fibers or push the stain deeper into the carpet. - Blot the Stain
After loosening the dried blood, the next step is to blot the area with a clean cloth or paper towel. Press down gently to lift the remaining blood particles. This step is crucial to prevent the stain from spreading further, so always blot from the outside. If you rub the stain, you may push the blood deeper into the carpet, making it harder to remove. - Apply Stain Remover
Once the dried blood has been loosened, it’s time to apply a stain remover. You can use a commercial carpet stain remover, a homemade solution from cold water, and a few drops of dish soap. Another option is hydrogen peroxide, which works wonders on dried blood but should always be tested on a hidden carpet area to ensure it doesn’t discolor your carpet.
Apply the stain remover directly to the stain and let it sit for about 5–10 minutes. This will give the solution time to break down the blood and make removing it easier. - Let the Stain Remover Sit
After applying the cleaner, it’s important to let it sit and work its magic. This step ensures the stain remover has time to penetrate the fibers and break down the dried blood particles. Do not rush this part – a few extra minutes can make a huge difference in lifting the stain effectively.
If you’re using hydrogen peroxide or another strong solution, it’s advisable to check the area every few minutes to ensure the carpet isn’t discolored. - Wipe the Stain with Water and Let It Dry
After the stain remover has had time to work, wipe the area with a clean cloth soaked in water. This will help dilute and remove the cleaning solution and any remaining blood residue.
Once the stain is removed, blot the area dry with a clean towel and allow it to air dry completely. To prevent dirt from sticking to the wet carpet, avoid walking on it until it’s fully dry.

How to Prevent Future Blood Stains on Carpet?
Preventing future blood stains is much easier than cleaning them, and it’s always better to be proactive. Here are some tips to help protect your carpet from future stains:
- Carry Stain Removal Tools with You:
If you tend to spill or get blood on your clothes, always have a portable stain remover or a few cleaning supplies. Carrying a small spray bottle of cold water and a cloth can save you from a permanent stain. - Use Carpet Protectors:
Invest in a carpet protector that repels liquids. These protectors form a barrier on your carpet fibers, making it harder for stains to soak in. Carpet protectors can be applied after cleaning or during routine maintenance. - Clean Up Spills Immediately:
The best way to prevent stains is to address them as soon as they happen. If you notice blood on the carpet, clean it immediately to prevent it from falling into the fibers. The quicker you act, the easier it will be to remove. - Avoid High-Risk Areas:
If you’re prone to accidents or injuries, consider setting up a “blood-free zone” where spills are more likely. Keeping the carpet in high-risk areas covered with a protective mat or rug can help minimize the chance of stains. - Regular Carpet Maintenance:
Regularly clean your carpet to maintain its condition and prevent dirt, dust, or oils from absorbing into the fibers. Vacuuming your carpet at least once a week and deep cleaning every few months will help keep it in top condition and reduce the risk of stains.
