How to Remove Blood Stains from Carpet - Simple DIY Guilde 2025

Accidents happen—especially when life’s hectic. A fresh blood stain on your carpet can be alarming, but you don’t need to panic. Acting quickly and using the right approach will prevent the stain from setting and keep your carpet fibres looking their best.

In this guide, we’ll show you how to remove blood stains from carpet safely and effectively, using household staples like cold water, mild detergent and hydrogen peroxide. Let’s dive in.

Why Acting Fast Is Crucial

How Blood Interacts with Carpet Fibres

When blood lands on carpet it begins to bond with the fibres immediately. The proteins in blood can adhere deeply, making removal harder if you wait. Blotting quickly prevents the stain from setting.

Risks of Letting Stains Set

If a blood stain dries, you risk permanent discolouration and damage to the pile. You’ll need stronger chemicals or even professional assistance, which costs more and may still not restore the original appearance.

Tools and Supplies You’ll Need

Cold Water and Absorbent Cloths

Always use cold water. Hot water can “cook” the blood proteins into the carpet, making the stain permanent. Keep clean, white cloths or paper towels on hand for blotting.

Mild Detergent Solution

A gentle dish soap mixed with cold water works wonders on fresh blood stains. Avoid harsh solvents that may discolour sensitive carpet dyes.

Hydrogen Peroxide and Enzyme Cleaners

For stubborn or dried stains, a 3% hydrogen peroxide solution can be effective. Enzymatic stain removers (designed for protein-based spots) are also useful—look for carpet-safe formulas.

Protective Gear and Safety Tips

• Wear disposable gloves to protect your skin from bloodborne pathogens.
• Ventilate the room if you’re using chemicals like hydrogen peroxide.
• Test any cleaner on an inconspicuous area first.

Step-by-Step Guide to Remove Fresh Blood Stains

1. Blot Excess Blood Immediately

Gently press your absorbent cloth onto the spot—never rub. Replace the cloth as it soaks up blood to avoid spreading the stain.

2. Apply the Detergent Solution

Mix one teaspoon of mild dish soap with a cup of cold water. Dampen (don’t soak) a clean cloth and blot the stain from the outside in, preventing a ring.

3. Rinse and Blot Dry

After the stain fades, blot with a cloth soaked in plain cold water to remove detergent residue. Finish by pressing dry cloths until the area is just damp.

4. Air Dry Completely

Allow the carpet to air dry. Avoid heat sources, as heat can set any lingering blood proteins.

Tackling Dried or Stubborn Stains

Using Hydrogen Peroxide Safely

Pour a small amount of 3% hydrogen peroxide onto the stain. You’ll see foaming—that’s the oxygen working to lift the blood. Blot after a few minutes, then rinse with cold water.

Alternative Stain Removers

If hydrogen peroxide isn’t suitable for your carpet, try an enzyme cleaner designed for protein-based stains. Follow the manufacturer’s instructions carefully and always test first.

Preventing Damage and Maintaining Your Carpet

Regular Carpet Care Tips

• Vacuum high-traffic areas weekly to prevent dirt buildup.
