Small stain on a cream carpet being blotted with a damp cloth beside a bowl of cold water

Wondering how to get blood out of carpet? Blot up what you can, then dab the stain with cold water on a white cloth. Never use hot water, because heat fixes blood into the fibres.

Work from the edge inwards and keep blotting until no more colour comes off. Dried blood needs softening first.

The right method depends on two things: how old the stain is, and what your carpet is made of. This guide covers both.

Before you start

What you need:

  • White kitchen roll or a clean white cloth (coloured cloths can transfer dye)
  • A bowl of cold water
  • A spoon or blunt knife for dried blood
  • A carpet spot remover suited to your carpet
  • Rubber gloves

Tried everything and the mark is still there? We can take a look.

Fresh or dried

Fresh or Dried? Pick Your Method First

How you remove blood from carpet depends on its age. Fresh blood is still wet and sits mostly on the surface. Dried blood has soaked into the pile and set, so it needs more time and patience.

Fresh blood

How to Get Fresh Blood Out of Carpet in 6 Steps

Speed matters most here. The WoolSafe Organisation says in its guide to cleaning and maintaining wool carpets that the older a stain is, the harder it is to remove.

  1. 1Blot, don't rub. Press white kitchen roll onto the blood to soak it up. Rubbing pushes blood deeper and spreads it.
  2. 2Wet the cloth, not the carpet. Put cold water on a clean white cloth, then dab the stain. Pouring water on the carpet can push blood down into the backing.
  3. 3Work from the outside in. Start at the edge of the stain and move towards the centre, so the mark does not get bigger.
  4. 4Keep going until the cloth stays clean. Turn the cloth to a clean part each time. Stop when no more colour transfers.
  5. 5Treat what is left. If a mark remains, use a carpet spot remover that suits your carpet. Test it on a hidden spot first, such as inside a wardrobe. No spot remover to hand? Which? suggests mild laundry detergent and water for wool or wool-blend carpets; read the wool section below first.
  6. 6Rinse and dry. Dab with a little clean cold water to remove any product, then blot as dry as you can and brush the pile back into place with your fingers.

Tip: put the spot remover on the cloth, not straight onto the carpet. Small amounts are easier to control.

Dried blood

How to Get Dried Blood Out of Carpet in 7 Steps

Dried blood on carpet is harder, but it is often worth a try before you call anyone. Go slowly and expect to repeat some steps.

  1. 1Lift loose bits. Gently scrape any crusty flakes off the surface with a spoon or blunt knife, then vacuum them up.
  2. 2Soften the stain. Dampen a white cloth with cold water and hold it on the stain for a few minutes. This softens the dried blood so it is easier to lift.
  3. 3Blot. Press with dry kitchen roll to draw out the loosened blood. Repeat the dampen and blot cycle a few times.
  4. 4Apply a spot remover. Use a carpet spot remover made for your fibre type. Leave it for the time the label gives. For blood on wool carpet, WoolSafe's guide suggests a WoolSafe approved pet stain remover on a damp white cloth.
  5. 5Blot again. Use clean kitchen roll and keep turning it. Do not scrub.
  6. 6Check the result once it is dry. A damp patch can look different from a dry one, so judge the result only when it is fully dry.
  7. 7Rinse and dry. Dab with clean cold water to take out any product, blot well and let air flow through the room.

Many people also ask about enzyme or biological products. Which? mentions enzyme-based detergents as an option for blood in its look at popular stain removal tips, but notes it had not tested them. If you use one, choose a product sold for carpets and follow its label.

Hydrogen peroxide

Is Hydrogen Peroxide Safe on My Carpet?

Many online guides suggest hydrogen peroxide for old blood stains. Be careful with it.

The UK government's general information on hydrogen peroxide says its main use is as a bleaching agent, including for textiles. So it can lighten your carpet's colour as well as the stain. The same page notes that even low strengths can whiten skin, so wear gloves.

Wool and Wool-Rich Carpets

Our advice is simple: do not use hydrogen peroxide on wool carpet. WoolSafe's guide says cleaning products for wool should contain no added bleaches. It also warns that strongly alkaline products can make dyes bleed and, in extreme cases, yellow and weaken wool fibres.

For blood out of wool carpet, start with cold water and a WoolSafe approved spot remover. If that does not shift it, ask a professional.

What about ordinary detergent? The two sources differ here. Which?'s carpet guide suggests mild laundry detergent and water for wool or wool-blend carpets. WoolSafe is stricter: its leaflet advises against household detergents on wool, and names washing-up liquid in particular. If you use laundry detergent, use very little, test on a hidden spot first and rinse it out well. Never use washing-up liquid on wool.

Man-Made Carpets

Some carpet spot removers for man-made fibres contain peroxide. If you want to try one, follow these rules:

  • Check the carpet maker's care advice first. If you do not have it, skip the peroxide.
  • Test on a hidden spot and let it dry fully before you judge the colour.
  • Use a product sold for carpets and follow its label.
  • Dab a small amount on the stain only, then rinse with cold water and blot dry.

Not sure what your carpet is made of? Look for the label on an offcut or the receipt. If you cannot tell, treat it as wool and skip the peroxide.

Common spills

Period Blood, Nosebleeds and Other Common Spills

The method is the same whatever the cause. A few situations need a little extra thought.

  • Period blood on carpet: treat it like any fresh blood stain. Cold water, blot, repeat. If it has dried overnight, follow the dried blood steps.
  • Nosebleed on carpet: drips are small but often spread over a wide area. Deal with each spot on its own, using a clean part of the cloth each time.
  • A pet's cut paw: clean the blood the same way, following the paw prints one spot at a time.
  • Large amounts of blood: wear rubber gloves while you clean. A big spill may have soaked into the underlay, which is hard to clean from the surface.

What to avoid

Mistakes That Set Blood Stains

What you do in the first few minutes matters most. Avoid these:

  • Hot water. Which? explains that blood proteins bind together when heated, which fixes the stain. Always use cold.
  • Rubbing or scrubbing. It spreads the stain and can damage the pile. Dab instead.
  • Soaking the carpet. Which?'s guide on how to clean a carpet by hand warns against using a lot of water, as stains can soak into the carpet.
  • Washing-up liquid on wool. WoolSafe's care leaflet for wool carpets and rugs says household detergents such as washing-up liquid can cause rapid re-soiling and colour bleeding on wool.
  • Ammonia on wool. Which? lists ammonia only as an option for carpets that are not wool, and only after checking with the manufacturer.
  • Household bleach. WoolSafe says products for wool should contain no added bleaches. Keep bleach well away from a blood stain.
  • Ignoring the label. WoolSafe's guide says spot removal chemicals must be used strictly in line with their safety instructions, in a well-ventilated area.
  • Skipping the rinse. WoolSafe notes that sticky residues make carpet soil again faster, so the spot can come back grey.

Professional help

When to Call a Professional

Some blood stains on carpet are not worth risking with more DIY. Call in help if:

  • The stain is old, large or has spread into the underlay
  • Your carpet is wool, wool-rich or a hand-made rug
  • You have already tried peroxide or bleach and the colour has changed
  • The mark keeps coming back after it dries
  • You are moving out and want the carpet looking its best

At Blowup Cleaners, spot treatment and a deodoriser are included with every carpet clean. For stubborn marks, our stain removal service starts from £15 per stain. Most common stains can be removed. Some may be permanent; we give honest advice before we start.

When you get in touch, tell us the stain is blood, roughly how old it is and what you have already tried. That helps us plan the right treatment.

If the whole room needs freshening up, we clean carpets across Manchester by hot water extraction (steam cleaning). See our carpet cleaning service for details. Drying time depends on the carpet, how dirty it is, airflow and weather. Our guide to carpet drying times after cleaning explains what speeds it up.

Not sure if the stain will come out? Ask us before you try anything stronger.

Questions

Common Questions About Blood on Carpet

Does salt get blood out of carpet?

It may help on a fresh stain. Which? explains that salt with cold water helps break down blood proteins so the stain lifts, though its tips are about fabrics rather than carpet. Rinse well with cold water afterwards and blot dry, so no salt is left in the pile.

How do you get blood out of a cream or light carpet?

Use the same cold water method, with white cloths only so no dye transfers. Light carpet shows any leftover product or colour change, so test every product on a hidden spot and rinse well with cold water. Skip peroxide unless the carpet maker's care advice allows it.

Does vinegar remove blood from carpet?

None of the sources we checked recommends vinegar for blood. Cold water and a carpet spot remover are the safer first choice.

Can you steam clean blood out of carpet?

Not as a first step. Heat can fix blood into the fibres, so treat the stain with cold water first. If a mark is still there afterwards, a professional can treat it before cleaning the whole carpet.

What about blood on a rug, sofa or mattress?

The same cold-water rule applies, but fabrics and rugs vary a lot. Check the care label and test first. If you are worried about damage, see our rug cleaning service, upholstery cleaning or mattress cleaning pages. Wool, silk, hand-made and antique rugs are priced after we see them.

For other marks such as wine, coffee or mud, read our guide to common carpet stains.
