The short answer

Lift the solids off carefully, then hand wash the lace in cold water with a gentle detergent, moving the water through the fabric rather than moving the lace about. Never twist or wring it: specialists single that out for lace because it distorts the structure permanently. Press the water out between towels and dry flat, supported.

If it has just happened

Take solids off with the flat of a knife rather than picking at them, because a fingernail catches the threads. Then get the lace flat and supported before any water is involved.

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.

Cleaning the mark is not the same as disinfecting

If the sickness came with a stomach bug rather than an ordinary posset, the surface may carry norovirus, which spreads easily and survives on hard surfaces. UK public health guidance is to wear gloves, avoid shaking contaminated laundry, wash affected laundry separately with normal powder at 60 C where the care label allows it, and disinfect compatible hard surfaces with a bleach based product afterwards. Do that after the stain work, not instead of it, and only where the material tolerates it.

Keep every kind of drying heat away until the mark has gone

Baby sick is mostly milk protein. Heat coagulates protein and locks it into the material, which is why a mark that would have washed out can become permanent after one hot wash, one pass with an iron, a hairdryer or a spell on a radiator. Cool or warm treatment, air drying, and a proper look in daylight before anything warm goes near it.

Never twist or wring lace

Specialists give this instruction for lace specifically. The structure holds together at fine junctions where the pattern turns, and twisting puts a shearing load through all of them at once. The pattern comes out of shape and it does not go back. Press the water out between towels instead, and ease the pattern straight with your fingers while it is still damp.

What you will need

  • Disposable gloves Sickness that came with a stomach bug is a hygiene job as well as a stain.
  • A spoon or the back of a knife For lifting solids off without pressing them into a fine weave.
  • White cloths White only. A coloured cloth can move dye onto a pale fabric in seconds.
  • Cold water Cold, which is what specialists specify for lace.
  • A mild non biological detergent Gentle and non biological, well diluted before the lace goes in.
  • A clean towel For pressing the water out. These fabrics are never wrung.

Fresh baby sick on lace

Speed helps, but going slowly and evenly helps more.

Go carefully with cold water

Lace 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. Take the solids off with a blade held flat

    The back of a knife or a spoon, held almost flat against the cloth and drawn across it. Do not dig into the weave.

  2. Blot from both sides with white cloth

    Put a dry cloth behind the fabric and press a second cloth onto the mark from the front. The backing cloth takes what comes through and stops it spreading.

  3. Rinse from the back in cool water

    Hold the mark face down and run cool water through the back of it, so the residue leaves by the shortest route rather than being pushed through the weave.

  4. Press the water out and dry flat

    Roll the fabric in a clean towel and press. Never twist. Lay it flat on a towel, ease the pattern back into shape with your fingers while it is damp, and leave it supported until dry.

  • How longTen minutes
  • RepeatingBlot rather than repeating a wet pass.
  • Stop ifthe residue has lifted and the fabric is evenly damp rather than spotted

Dried baby sick on lace

A short soak, evenly, is safer than any amount of local attention.

Go carefully with soaking

Lace tolerates soaking only within limits. Keep contact time short, work from the edge of the mark inwards and stop if the material changes.

Go carefully with cold water

Lace 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. Flex the fabric to crack the residue off

    Dried milk sits on the surface of a smooth fabric and much of it flakes away if you simply work the cloth between your fingers.

  2. Soak the whole panel, not the spot

    Cool water with a little mild detergent, and put the whole panel in rather than dipping the mark. Half an hour is the limit, because these fabrics weaken the longer they stay wet.

  3. Move the water through the mark by squeezing

    Squeeze gently where the mark is to push fresh solution through it. Do not rub the fabric against itself.

  4. Rinse fully and dry flat, away from sun

    Detergent left behind marks these fabrics as readily as the stain does. Rinse until the water is clear and dry away from direct heat and sunlight.

  • How longUp to 30 minutes
  • RepeatingOne soak, then a decision.
  • Stop ifthe mark has gone, or one soak has not moved it

Old or set in baby sick on lace

Old marks on delicate fabric are usually where the honest answer is a specialist.

  1. One longer soak in cool water

    An hour at most, with a mild detergent, moving the water through the mark by squeezing every so often. Longer than that costs more in fibre strength than it gains in stain removal.

  2. Rinse, press and dry flat before judging

    These fabrics look far worse wet. Give it a full day and look at it dry and in daylight before making any decision.

  3. Then take it to a specialist

    A dry cleaner who handles delicates can wet spot a protein mark under controlled conditions and knows what the fabric will take. Tell them it is milk, because solvent cleaning on its own is poor at protein stains.

  • How longOne long soak, then a decision
  • RepeatingDo not repeat. Repeated wetting is what damages these fabrics.
  • Stop ifthe mark has faded as far as it will, or you have decided to use a specialist cleaner

What not to use on lace

  • Rubbing, scrubbing or wringing

    These fabrics are damaged by the handling rather than by the stain. Silk fibres break and go dull, lace distorts, satin picks up a permanent shine, and viscose loses strength entirely when it is wet.

  • Chlorine bleach and oxygen bleach powders

    Chlorine bleach dissolves silk and weakens lace and viscose. Oxygen powders are gentler but still lighten dyes unevenly on a fabric where any patch shows.

  • Hot water, an iron on the mark, a tumble dryer or a hairdryer

    Milk protein sets with heat, and every fabric on this page is separately heat sensitive. A hot treatment fixes the stain and damages the cloth in the same movement.

  • Treating a small spot in the middle of a panel

    On these fabrics the water leaves its own ring. Working the whole panel out to its seams, or wetting nothing at all, are the two safe options. A damp circle in the middle of a dry panel is the outcome to avoid.

  • Biological detergent left on for a long time

    Silk is a protein fibre, so protease enzymes attack it as readily as they attack the milk. A short contact time on a cellulose fabric is one thing, a long soak on silk is another.

  • Picking at dried residue with a fingernail or a pin

    A fingernail catches the fine threads and pulls them out of the pattern. Dissolve dried milk with a cold soak instead of trying to lift it off.

White compared with coloured lace

Old cotton and linen lace is usually an uneven cream rather than white, and bleaching a mark out of it leaves a bright patch on an aged ground that looks worse than the stain. Synthetic lace holds its colour but snags easily, and a pulled thread on a lace pattern is far more visible than a faint mark. Protect the structure ahead of the colour.

If the mark is still there

Dry it flat and supported, and look at it once it is fully dry. Damp lace clings to itself and looks far worse than it is.

If a stiff patch remains where milk has dried between threads, a second cold soak with the water squeezed gently through the area usually finishes it. Work with fingertips, never a brush.

If the piece is antique, heirloom or attached to something like a wedding dress, stop earlier than you otherwise would. A textile conservator or a specialist cleaner deals with old lace as a matter of routine, and old lace is the one fabric here where an amateur attempt regularly does damage that cannot be undone.

When to stop and call someone

Use a specialist cleaner or a textile conservator rather than continuing if the lace is antique or heirloom, if it is attached to a garment you cannot lay flat, if threads have already pulled, or if one cold soak has not shifted a stiff patch. Say what the stain is, because milk needs a water based treatment rather than solvent.

Why baby sick behaves this way on lace

Lace is an openwork structure where the design is made from the holes.

The junctions are the weak points

Fine threads meet at the points where the pattern turns, and those junctions carry the load. Twisting or wringing puts a shear force through every one of them at once, which is why the pattern comes out distorted and stays that way.

Milk glues threads together

Dried milk stiffens fine threads and can bond neighbouring ones. That is why a dried mark on lace feels crisp and why cold soaking, which dissolves the residue rather than dislodging it, works better than any mechanical approach.

It snags on everything

Including itself, a washing machine drum, a fingernail and a ring. A mesh bag or a sandwich between two white cloths removes most of that risk.

Age changes the answer

On old lace, the ground colour is uneven and the threads are already weakened. Both facts push the sensible answer towards a specialist much sooner.
