The short answer

Work on the fleece and keep the skin behind it as dry as you can. Lift the solids, rinse the wool in cold water no warmer than 30 C, and use a wool specific detergent only, because ordinary detergent strips the natural oils and leaves the fleece brittle and matted. Squeeze rather than wring, never tumble dry, and brush the fleece back with a slicker brush once it is completely dry.

If it has just happened

Lift the solids off the fleece and blot the wool without pressing the liquid down into the skin. On a sheepskin the aim from the first second is to keep the mark in the fleece and out of the leather.

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.

Two materials, one item

A sheepskin is wool on tanned leather, and they want opposite things. The fleece would tolerate a proper wash. The hide would not, and a soaked hide dries hard and can crack along the folds. Everywhere on this page where the instruction looks over cautious about water, the leather is the reason.

What you will need

  • Disposable gloves Sickness with a stomach bug is a hygiene job too.
  • A spoon or blunt scraper For lifting solids out of the fleece.
  • White cloths For blotting the wool without pressing liquid into the skin.
  • Cold water, no warmer than 30 C The tannery's own limit. Warmer water shrinks the hide.
  • A wool specific detergent Ordinary detergent strips the lanolin and leaves the fleece brittle and matted.
  • A slicker brush For bringing the fleece back once it is completely dry. This step does most of the visible work.

Helpful but not essential

  • Bicarbonate of soda Brushed through the dry fleece for any smell that is left.

Fresh baby sick on sheepskin

Keep the liquid in the fleece and out of the leather backing behind it.

Go carefully with cold water

Sheepskin 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. Lift the solids out of the wool

    A spoon, working with the lie of the fleece rather than against it, so you are not pushing material down towards the skin.

  2. Blot the fleece without pressing

    Press white cloth onto the wool and lift. Heavy pressure drives liquid into the leather, which is the one thing to avoid here.

  3. Rinse just the marked wool, in cold water

    Hold the sheepskin so the marked area is over a sink and run cold water through the fleece only, keeping the backing out of it as far as you can. No warmer than 30 C.

  4. Squeeze, do not wring, and dry flat in the air

    Press the water out between towels. Lay it flat, out of the sun and away from any radiator, and leave it a day or two.

  • How longFifteen minutes, then a day or two to dry
  • RepeatingBlot until a dry cloth stays clean.
  • Stop ifthe fleece is clean, the backing is no more than slightly damp and it is laid out to dry

Dried baby sick on sheepskin

A dried mark on a sheepskin usually needs a proper wash of the whole skin, which is a bigger decision.

Go carefully with cold water

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

Go carefully with soaking

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

  1. Check the label before wetting the whole skin

    Many sheepskins are hand washable and some are strictly dry clean only. Washing a dry clean only skin relaxes the leather around the seams and is not recoverable.

  2. Break the dried material out of the fleece

    Work it apart with your fingers and a blunt scraper, then shake it out. The less that has to be dissolved, the less water goes near the hide.

  3. Hand wash in cold water with wool detergent

    No warmer than 30 C, wool detergent only, and gentle squeezing rather than agitation. Keep it short.

  4. Squeeze out, dry flat, then brush

    Press the water out in towels, dry flat away from heat for a day or two, then work a slicker brush through the fleece to bring it back.

  • How longAn hour, then two days to dry
  • RepeatingOne wash. Do not repeat wash a sheepskin.
  • Stop ifthe fleece is clean and drying flat, or the label rules out washing and a specialist is needed

Old or set in baby sick on sheepskin

Old milk in a fleece is a smell problem more than a colour one.

  1. Make sure it is bone dry first

    Bicarbonate of soda does nothing in a damp fleece and damp wool on a hide is how mould starts. Dry it completely before this step.

  2. Work bicarbonate of soda into the fleece

    Sprinkle generously, work it down to the base of the wool with your fingers, and leave it overnight.

  3. Shake and brush it out

    Take it outside, shake it hard, and brush the fleece through with a slicker brush. Tanneries advise against vacuuming a sheepskin, so shaking and brushing is the way the powder comes out.

  4. Then use a sheepskin specialist

    If the smell survives, the material is in the hide rather than the fleece. A specialist sheepskin cleaner can handle that. An ordinary dry cleaner may harden the skin, so ask specifically.

  • How longOvernight, then a decision
  • RepeatingOne powder treatment, then a specialist.
  • Stop ifthe smell has gone and the fleece brushes out soft, or a specialist cleaner is needed

What not to use on sheepskin

  • Soaking the whole sheepskin or letting the leather get thoroughly wet

    The tannery's own guidance is not to saturate a sheepskin, because liquid seeping into the leather damages or stains it and the hide dries hard. Spot treat the fleece instead.

  • Ordinary laundry detergent, biological detergent or washing up liquid

    These strip the natural oils out of the fleece and leave it brittle and matted, and biological detergent digests the wool and the hide alike. A wool specific detergent is the only correct product.

  • A tumble dryer, a radiator or a hairdryer

    Heat shrinks the wool fibres and the hide together, permanently, and it sets the milk protein at the same time.

  • Wringing it out

    Twisting a wet hide creases and cracks it. Squeeze it between towels instead.

  • Vacuuming the fleece

    Tanneries advise against it. A vacuum pulls the wool out of the skin. Shake it and brush it instead.

White compared with coloured sheepskin

Natural sheepskin is off white and cream with variation across the hide, and dyed sheepskins are surface dyed rather than dyed through. Bleach and strong detergent both take colour off unevenly and leave a hard patch as well as a pale one. Matting, not staining, is the usual visible outcome of a badly handled sheepskin, and it can often be brushed out once dry.

If the mark is still there

Wait until it is completely dry before judging anything, and that can take two days. A sheepskin dries stiff and looks ruined, then softens and fluffs up once it is brushed.

Brushing is the step people skip. A slicker brush worked through the dry fleece separates matted fibres and brings the loft back, and it does more for the appearance than any further washing would.

If the skin has gone hard, work it gently over the edge of a table to break the stiffness, which tanneries suggest for a sheepskin that has been wetted. If a smell remains in the fleece, bicarbonate of soda brushed through the dry wool overnight and shaken out is safe and often enough. If it remains after that, a specialist sheepskin cleaner is the answer rather than another wash.

When to stop and call someone

Use a specialist sheepskin cleaner rather than continuing if the sick soaked right through to the leather, if the hide has gone hard and does not soften with working, if the label says dry clean only, or if a smell remains after the fleece has dried and been treated with bicarbonate of soda. Ordinary dry cleaning is not the same thing and can harden a skin.

Why baby sick behaves this way on sheepskin

A sheepskin is a tanned hide with the fleece left on, so you are cleaning two materials at once that want opposite treatment.

The leather is the limiting factor

The tannery's own instruction is not to saturate a sheepskin, because liquid seeping into the leather damages or stains it. A wet hide dries hard, and a hard hide cracks along fold lines. That is why spot cleaning beats washing whenever the mark is small enough to allow it.

The fleece needs its oils

Ordinary laundry detergent strips lanolin out of the wool. The tannery's guidance is a wool specific detergent only, because the alternative is a fleece that is brittle and permanently matted.

Heat shrinks both halves

Tumble drying shrinks the wool fibres and the hide together. A sheepskin pram liner or a rug that has been dried with heat does not go back to its original size or softness.

Milk and a nursery item

Sheepskin liners are common in prams and cots, which is why milk marks on them are common too. Cool water and time are still the answer, and a thorough rinse matters because residue sits next to a baby.
