The short answer

Wipe it up with a cloth wrung out in cold water with a drop of washing up liquid, then dry the floor immediately. Laminate has a sealed wear layer, so the mark itself is straightforward. The board underneath is not sealed, so the rule is damp, never wet, and no steam cleaner at any point.

If it has just happened

Blot the liquid up with kitchen paper before it can find a joint between boards, then wipe with a barely damp cold cloth and dry the area with a towel.

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.

Blood that is not your own needs gloves

Your own menstrual blood carries no risk to you that it did not already. Someone else's does. Infection control guidance is to put on disposable gloves and an apron where contact with blood is expected, and to cover any cut or graze on your hands with a waterproof dressing before you start. That applies to a small mark on a sheet in a shared house as much as to a large spill.

Damp, never wet

Laminate makers ask for a slightly damp mop and no standing water. On a spill that means blotting first and wiping second, and drying the area straight afterwards. Almost all serious damage to laminate floors comes from the cleaning rather than the spill.

What you will need

  • Two clean white cloths White, so no dye transfers into whatever you are treating.
  • Cold water
  • Washing up liquid One drop. More than that is harder to rinse out than the mark was.
  • White kitchen paper Six to eight sheets, for drawing moisture back out under a weight.

Helpful but not essential

  • Disposable gloves Optional if the blood is your own, sensible if it is not.

Fresh period blood on laminate flooring

Get the liquid off the floor before it finds a joint, then dry.

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 it up

    Kitchen paper pressed straight down, repeatedly, rather than wiped. Wiping pushes the liquid towards the joints between boards.

  2. Wipe with a well wrung damp cloth

    Cold water with one drop of washing up liquid, on a cloth wrung out until it is barely damp. Work over the mark, not around the room.

  3. Dry immediately

    Go over the area with a dry towel. Standing water is the thing manufacturers warn about, and drying takes ten seconds.

  • How longThree minutes
  • RepeatingOne pass, then dry. A second damp pass only if it is genuinely still there.
  • Stop ifthe floor is clear and dry

Dried period blood on laminate flooring

Softening a dried mark on a sealed floor takes a minute and no more moisture than that.

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. Lay a damp cloth on it

    A cloth wrung out in cold water, left on the mark for two minutes. The dried film rehydrates because none of it is in the floor.

  2. Wipe with detergent

    One drop of washing up liquid on a damp cloth, light pressure, no abrasive pad and no scrubbing brush.

  3. Dry the area

    Towel it dry, then look at it dry before deciding whether to repeat. A damp laminate floor hides a faint mark.

  4. Bicarbonate if a shadow is left

    A little bicarbonate of soda on a damp cloth, worked gently, then wiped off and dried. This is as far as it is sensible to go.

  • How longFive minutes
  • RepeatingTwo passes, drying after each.
  • Stop iftwo damp passes make no further difference

Old or set in period blood on laminate flooring

An old mark on laminate is either in a scratch or in the surface texture. Neither responds to more force.

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 and wipe again

    Damp cloth for five minutes, then detergent on a cloth. Old blood on a sealed surface still comes off more often than people expect.

  2. Bicarbonate on a damp cloth

    Worked gently over the mark, then rinsed off with a damp cloth and dried. Do not use a cream cleanser containing grit, and do not use a melamine sponge, which is an abrasive.

  3. Judge it dry and stop

    If it has not moved, it is under the wear layer or in a scratch, and stronger attempts only dull the finish around it, which is more visible than the mark.

  • How longTen minutes
  • RepeatingOne attempt with bicarbonate, then stop.
  • Stop ifthe mark is unchanged after a bicarbonate pass, which means it is below the wear layer

What not to use on laminate flooring

  • A steam cleaner

    Manufacturers rule steam out on any laminate not sold as waterproof, because it drives moisture into the joints. It is also heat, which sets the protein and makes the mark harder to remove.

  • A wet mop or standing water

    The fibreboard core swells where water reaches a joint, and a swollen joint lifts. It cannot be dried back into shape.

  • Abrasive pads, melamine sponges and gritty cream cleaners

    They dull the wear layer permanently, and a dull patch collects dirt faster than the rest of the floor.

  • Anything warm before the mark has gone

    Heat coagulates the protein in blood inside the fibre or the pore it is sitting in, and nothing reverses that. A warm rinse, a hot wash, a tumble dryer, an iron, a steam cleaner and a hairdryer all do it.

White compared with coloured laminate flooring

The decor is a printed layer under a clear wear layer, so it is protected from most things while that layer is intact. Bleach can lighten a dark or matt laminate given time on the surface, and there is no reason to let it sit here. Test at the edge of the room if you use anything stronger than detergent.

If the mark is still there

A faint mark left after a wipe is usually in the surface texture rather than in the floor. Bicarbonate of soda on a damp cloth, worked gently and then wiped off and dried, is the strongest thing that is safe.

What does not come out is anything that has reached a joint. Liquid that gets between two boards swells the fibreboard core, and the edge lifts or the joint opens. That is a board replacement rather than a cleaning problem, and it happens far more often from the treatment than from the original spill.

If the wear layer itself is scratched and the mark is in the scratch, nothing removes it.

When to stop and call someone

Nothing here needs a professional. If a joint has swollen or a board edge has lifted, a flooring fitter replaces the affected boards, which on a click floor is usually possible without lifting the whole room.

Why period blood behaves this way on laminate flooring

A laminate floor is a hard wear layer over a printed decor over a fibreboard core. The top is tough enough that blood cannot penetrate it, so the stain part of this is easy: cold water and detergent lift it in one pass.

Everything else about the method exists to protect the core. Manufacturers ask for a slightly damp mop and no standing water, and they rule out steam cleaners on anything not specifically sold as waterproof. Steam is a double problem on a blood mark, because it drives moisture into the joints and it is heat, which coagulates the protein and makes the mark harder to wipe off rather than easier.

Abrasives are the other permanent risk. The wear layer is what makes the floor cleanable, and a dulled patch in it collects dirt for the rest of the floor's life.

Do the usual suggestions work?

  • Cold water and washing up liquid Yes, it works

    On a sealed floor this removes a fresh mark in one pass.

  • Bicarbonate of soda on a damp cloth Sometimes

    Mild enough for the wear layer, and worth one attempt on a mark sitting in the texture.

  • White vinegar in water Sometimes

    Often recommended for laminate generally and of no use on protein. Never after anything containing bleach.

  • A steam mop No, it is risky

    Two problems at once: heat that sets the mark and moisture forced into the joints.

  • A melamine sponge No, it is risky

    It works by abrading. On a laminate wear layer that leaves a permanent dull patch.

Common questions

My laminate says it is waterproof. Does that change anything?

It changes how much you have to worry about the joints, not the method. Waterproof laminate still has a wear layer that abrasives dull and a decor layer that bleach can lighten, and a damp cloth still removes the mark faster than anything else.

Can I use a floor cleaner spray instead?

Yes, if it is one the floor maker allows. It will not do more than cold water and detergent on a blood mark, and the reason to prefer it is that it is designed to dry without leaving a film.

Why is it brown rather than red?

Menstrual blood is darker than a cut to begin with, because it is not freshly oxygenated, and the iron in it oxidises further as it dries. Brown means old, not set. It responds to the same cold soak.
