The short answer

Blot it immediately, then wash the area with cold water and a little washing up liquid. If a shadow is left, the stone trade's method for an organic stain is a poultice: a paste of hydrogen peroxide and a white absorbent powder spread over the mark, covered, and left a day or two to draw the stain out of the pore structure. Never use vinegar, lemon juice or any acidic cleaner, and never scour it.

If it has just happened

Blot with kitchen paper pressed straight down. Do not wipe, which spreads the liquid across the surface and gives more of it time to be absorbed. Then rinse the area with cold water and blot again.

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.

Sealed marble still absorbs

A sealer slows absorption, it does not prevent it, and sealers wear. If you do not know when the surface was last sealed, assume the stone is taking liquid in and act quickly rather than leaving the mark to be dealt with later.

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.
  • A white absorbent powder Kaolin, whiting, fuller's earth or talc. Not flour and not anything coloured.
  • Cling film and tape To cover the poultice so it stays damp for the first day.

Helpful but not essential

  • Disposable gloves Optional if the blood is your own, sensible if it is not.
  • Hydrogen peroxide, 3 percent White and pale materials only, and test somewhere hidden first.

Fresh period blood on marble

Speed matters more on marble than on anything else here, because the stone is absorbing while you decide.

Go carefully with cold water

Marble 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 straight down

    Kitchen paper pressed onto the mark and lifted, repeatedly, with a clean area each time. Do not wipe it across the stone.

  2. Wash with cold soapy water

    A cloth damped in cold water with one drop of washing up liquid. Work over the mark and rinse the cloth often.

  3. Rinse and blot dry

    Clean cold water on a cloth, then blot the area dry with a towel.

  4. Judge it dry

    Marble looks clear while it is damp. Let it dry completely, in daylight, before deciding whether a poultice is needed.

  • How longFive minutes, plus drying
  • RepeatingBlot repeatedly. Two or three washes at most.
  • Stop ifthe surface is clear once it has dried completely

Dried period blood on marble

The poultice method. Slow, undramatic, and the thing the stone trade actually specifies.

  1. Test somewhere hidden

    Put a small amount of 3 percent hydrogen peroxide on an offcut or a hidden edge and let it dry. Some darker and veined marbles lighten, and that is worth knowing before it happens where it shows.

  2. Mix the poultice

    Stir a white absorbent powder such as kaolin, whiting or talc into 3 percent hydrogen peroxide until it is the consistency of thick paste.

  3. Apply it thickly and cover

    Spread it a quarter to a half inch thick over the mark and about an inch beyond it, cover with cling film taped at the edges, and leave it twenty four hours.

  4. Uncover, dry, and lift it off

    Take the cover off and let the poultice dry out completely, which is the stage that draws the stain up into the powder. Scrape it off with a plastic scraper, rinse with cold water and dry.

  • How longTwenty minutes of work, then one to two days of waiting
  • RepeatingUp to three poultices. Each one takes a little more out.
  • Stop ifa full poultice cycle makes no visible difference

Old or set in period blood on marble

An old organic mark in stone is the same method with more repeats and lower expectations.

  1. Repeat the poultice

    Mix, apply, cover, wait, dry, remove. Three cycles is a reasonable amount of effort for a mark that matters.

  2. Assess between cycles, dry

    Judge only when the stone is fully dry. Damp marble hides both progress and its absence.

  3. Do not escalate the chemistry

    Stronger peroxide, bleach or a household descaler are all worse ideas than a fourth poultice. The descaler in particular is an acid and will etch the surface.

  4. Call a stone restorer

    They have controlled treatments and can hone and re polish a small area. Tell them exactly what has been on the stone already.

  • How longSeveral days across repeated poultices
  • RepeatingThree poultice cycles, then hand it over.
  • Stop ifthree poultices leave the mark essentially unchanged

What not to use on marble

  • Vinegar, lemon juice and any acidic cleaner

    Marble is calcium carbonate and acid dissolves it. The result is a dull etched patch that is permanent and usually more visible than the stain was. This is not a question of dilution or contact time.

  • Scouring pads, powders and abrasive creams

    A polished marble surface scratches easily, and a scratched patch cannot be buffed out at home.

  • Chlorine bleach

    It is not needed here, it can discolour stone, and the stone trade specifies hydrogen peroxide for an organic stain instead. It must also never be mixed with ammonia, which the trade body states in capitals.

  • 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 marble

Marble is porous, and how badly it stains depends on whether it is sealed and how recently. A sealed worktop may give up a fresh mark completely. An unsealed or worn hearth or bathroom slab absorbs quickly and needs the poultice route. Test on an offcut or a hidden edge, because household hydrogen peroxide can lighten some darker or veined marbles.

Products that genuinely help here

Try the household route above first. These are worth buying only when it is not enough.

  • Optional product

    Pure Safe hydrogen peroxide 3 percent solution, 500 ml

    The liquid half of the poultice

    The poultice method needs a reasonable volume of hydrogen peroxide rather than the few drops a fabric stain uses, and it may need repeating three times. A 500 ml bottle at household 3 percent strength covers that, and peroxide decomposes on the shelf so an old part used bottle is a common reason a poultice appears not to work.

    Worth knowing. Never mix it with vinegar or any other acid, and keep it off darker or heavily veined marble until a hidden test has dried.

If the mark is still there

A poultice is a slow method and repeating it is normal. The stone trade allows for several applications on a stubborn organic stain, and each one draws a little more out.

Make it again, spread it a quarter to a half inch thick, extend it about an inch past the mark, cover it with plastic and leave it twenty four to forty eight hours before removing the cover and letting it dry out completely. It is the drying that pulls the stain up into the powder.

If three poultices have not cleared it, a stone restorer can go further, including a controlled chemical treatment or a light honing of the surface. That is genuinely specialist work and worth paying for on a worktop or a fireplace.

Etching is a separate problem. If the surface has gone dull or slightly rough where something acidic touched it, that is not a stain and no poultice affects it.

When to stop and call someone

Bring in a stone restorer if the mark is on a polished worktop or a fireplace where appearance matters, if three poultices have not cleared it, if the surface has been etched by something acidic, or if the marble is antique or part of the building. Say what has already been applied, because it changes what they can do next.

Why period blood behaves this way on marble

Marble is calcium carbonate, which creates two separate constraints.

The first is porosity. Liquid is drawn into the stone rather than sitting on it, so a mark can be inside the surface rather than on it. That is why the trade method is a poultice, which is a paste that holds a solvent against the stone and then draws it back out as it dries, carrying the stain with it. Wiping the surface cannot do that.

The second is acid sensitivity, and it is absolute. Acid dissolves calcium carbonate, so vinegar, lemon juice, limescale removers and acidic bathroom sprays etch marble on contact, leaving a dull rough patch. This matters here because vinegar and lemon are two of the most widely repeated pieces of period stain advice, and on marble they cause permanent damage that is more visible than the stain.

Blood counts as an organic stain, for which the stone trade specifies a hydrogen peroxide poultice. Household peroxide is 3 percent against the 12 percent they call for, so the household version is the cautious one and needs more repeats.

Do the usual suggestions work?

  • Hydrogen peroxide poultice Yes, it works

    The stone trade's own method for an organic stain, and the only household route that reaches into the pores.

  • Cold water and washing up liquid Sometimes

    Enough for a fresh mark on a well sealed surface, and not enough for anything absorbed.

  • Bicarbonate of soda paste Sometimes

    It works as the absorbent half of a poultice. It is the peroxide that does the chemistry, not the powder.

  • Lemon juice No, it is risky

    Widely recommended for blood marks and one of the worst things available for marble. It etches the surface permanently.

  • White vinegar No, it is risky

    The same problem as lemon juice. Acid on calcium carbonate dissolves the stone.

Common questions

How do I know if my marble is sealed?

Put a few drops of water on it and leave them four or five minutes. If the stone darkens where the water sat, it is absorbing and needs sealing. If the water beads and the stone is unchanged, the sealer is still working.

The surface has gone dull where I treated it. Can that be fixed?

That is etching rather than staining, and it means something acidic touched the stone. It is not removable by cleaning. A marble polishing powder can improve a small dull patch, and anything larger is a job for a stone restorer.

It happened overnight and I only found it this morning. Is that too late?

No. Drying is not the same as setting. A mark that has dried but has never been heated has only gone out of solution, and cold water plus time brings it back. The thing that would make it too late is a warm wash or a tumble dryer, not the hours it sat there.
