The short answer

Blot it up, then wipe with a well wrung cloth and a little mild detergent in cold water, working towards the middle of a board rather than along a joint. Dry it straight away. No steam mop, no wet mop and nothing abrasive.

If it has just happened

Blot it up with kitchen roll before it can run into a seam between boards. Getting it off the joint matters more than getting it off the surface.

Heat can set this stain permanently

Do not use hot water, a tumble dryer, an iron or a steam cleaner until the mark has gone. Heat fixes this type of stain into the fibres and makes it far harder to shift.

Test on a hidden area first

Try any cleaner on a hidden part of the material first, such as a seam, an offcut, inside a hem or under a piece of furniture. Wait for it to dry and check for colour change before treating the visible mark.

Treat blood that is not your own as a hazard

Blood can carry bloodborne viruses. If it is not your own, put disposable gloves on before you start, cover any cut or graze on your hands with a waterproof dressing first, and wash your hands when you have finished. That is the standard precaution, and it applies to a small mark on a sheet as much as to a large one.

The joints are the part that cannot be repaired cheaply

Nothing you do to the surface of a laminate floor is likely to be permanent. Water that gets into a seam is. Keep the cloth wrung out, work across boards rather than along the gaps between them, and dry as you go.

What you will need

  • Disposable gloves Assume any blood that is not your own needs them.
  • Kitchen roll
  • Two cloths, one damp and one dry The dry one is not optional on this floor.
  • Cold water

Helpful but not essential

  • Washing up liquid A trace only. Manufacturers rule out natural soap detergents.
  • A plastic scraper or an old bank card For dried blood and for working along a seam.

Fresh blood on laminate flooring

Get it up before it finds a joint, and dry behind yourself as you go.

Go carefully with cold water

Laminate flooring tolerates cold water only within limits. Keep contact time short, work from the edge of the mark inwards and stop if the material changes.

  1. Blot, do not spread

    Press kitchen roll onto the spill and lift. Wiping pushes liquid outwards and towards the nearest joint, which is the one place it must not go.

  2. Wipe with a well wrung cloth

    Use a cloth wrung out in cold water with a trace of washing up liquid, so damp rather than wet. Work towards the centre of a board rather than along the line between two.

  3. Dry immediately

    Go over the area with a dry cloth straight away. Manufacturers are specific that standing water is what damages laminate, and a floor left to air dry after a spill has had liquid sitting on it for longer than it needed to.

  4. Check the seams

    Look along the joints around where the spill was. Anything dark in a seam needs dealing with now, with a barely damp cloth over a plastic scraper, and drying straight afterwards.

  • How longFive minutes
  • RepeatingOne wipe and one dry. Repeating means more water on the floor, which is the wrong direction.
  • Stop ifthe surface is clean, or you can see liquid tracking into a seam

Dried blood on laminate flooring

Soften and lift. The one thing not to do here is abrade it.

Go carefully with cold water

Laminate flooring tolerates cold water only within limits. Keep contact time short, work from the edge of the mark inwards and stop if the material changes.

  1. Soften with a damp cloth

    Lay a cloth wrung out in cold water on the mark for five minutes. On a sealed surface that is usually all a dried mark needs.

  2. Lift it with a plastic edge

    Hold a plastic scraper or an old bank card almost flat and push the softened material off the surface. Nothing metal, no scouring pad and no wire wool, all of which scratch the wear layer permanently.

  3. Wipe and dry

    Wipe the area with a barely damp cloth with a trace of detergent, then dry it immediately with a second cloth.

  • How longTen minutes
  • RepeatingTwo rounds of softening. Not three, and never with more water.
  • Stop ifthe mark stops lifting, or the surface looks scratched where you have worked

Old or set in blood on laminate flooring

On this floor an old mark is either in a seam or under a damaged wear layer, and those need opposite responses.

Go carefully with cold water

Laminate flooring tolerates cold water only within limits. Keep contact time short, work from the edge of the mark inwards and stop if the material changes.

  1. Work out where the mark actually is

    Look along the floor at a low angle. A mark on the flat of a board with a smooth surface over it should still lift. A mark in a joint, or one under a visibly scratched or worn patch, will not.

  2. One controlled attempt on the flat

    Ten minutes under a cloth wrung out in cold soapy water, then lift with a plastic edge and dry immediately. That is the ceiling of what is safe on a laminate floor.

  3. Leave the seam alone and get advice

    If it is in a joint, stop. Flushing a seam to clean it is how a swollen edge starts, and a swollen edge is a board replacement rather than a cleaning problem. Dry the joint, and ask a fitter what replacing that board would involve.

  • How longFifteen minutes
  • RepeatingOne careful attempt. There is no version of this that gets better with more water.
  • Stop ifthe mark is in a seam or under a scratch, at which point stop rather than continuing

What not to use on laminate flooring

  • A steam mop

    Laminate manufacturers exclude steam on standard laminate because it forces moisture into the seams, and steam also sets blood into anything porous it reaches.

  • A wet mop or a bucket of water

    Manufacturers specify a slightly damp mop and no standing water. Water in a seam swells the fibreboard core, and that damage is permanent.

  • Abrasive pads, wire wool and gritty cream cleaners

    Both major laminate makers rule these out. They scratch the wear layer, and a scratched floor stains in that spot from then on.

  • Neat bleach

    It is unnecessary on a sealed floor, it can lighten a dark or matt decor, and any of it that runs into a seam sits there in contact with the core.

  • Letting it air dry after cleaning

    Every extra minute of moisture on the floor is time for it to find a joint. Drying with a cloth immediately is part of the method rather than tidying up afterwards.

White compared with coloured laminate flooring

The decor on laminate flooring is a printed layer under a clear wear coat, so a cleaner cannot lift its colour. What shows damage is the sheen and the joints. A dark or matt floor shows a dulled patch clearly, so test at the edge of the room under furniture before working on anything in the open.

If the mark is still there

A blood mark should not survive a wipe with mild detergent on this surface, so if something is still there, look at where it is rather than reaching for something stronger.

If it is in a seam, it has run into the joint and it will keep showing as a dark line. Work along the joint with a barely damp cloth wrapped around a plastic scraper, then dry it immediately. Do not flood the joint to flush it out, which is the instinct and which is exactly how a swollen edge starts.

If it is on the flat and it will not lift, the wear layer is scratched or worn there. That is not removable and no cleaner reaches under it.

When to stop and call someone

Call a flooring fitter rather than trying harder if boards have swollen, lifted or separated at a joint, or if blood has run into a seam and shows as a dark line you cannot reach. Both are board replacement jobs, and in a click floor a single board in the middle of a room is not a straightforward swap.

Why blood behaves this way on laminate flooring

Laminate flooring is a printed decor sealed under a melamine wear layer on a high density fibreboard core, with the boards clicked together at the edges.

The surface is genuinely tough, so blood on the flat of a board is a two minute job. The joints are the weakness. They are a mechanical fit rather than a seal, so liquid that sits in one reaches the fibreboard, and fibreboard swells when it gets wet and does not shrink back. A swollen joint shows as a raised, slightly rough line and the only fix is replacing boards.

That is also why manufacturers exclude steam cleaners on standard laminate. Steam does not just make the floor wet, it drives moisture into the seams under pressure.

Common questions

My laminate is sold as waterproof. Does that change this?

It changes how much slack you have, not the method. Waterproof ranges have sealed or treated joints and some makers permit steam on those specifically. Check what your floor actually is before relying on it, because most laminate sold is not that.

Is there a floor cleaner I should be using instead?

Manufacturers sell their own and they are fine. For a blood mark the active question is water and temperature, not which cleaner, so a trace of washing up liquid on a wrung out cloth does the same job.

It got into the gap between two boards. Can I flush it out?

No. Adding water to a seam is the single thing this floor cannot take. Work along the joint with a barely damp cloth over a plastic scraper, accept what does not come out, and dry it.
