The short answer

Part the pile with your fingers and treat the base of the strands and the backing, because that is where the sick has run to. Scrape and blot rather than rubbing, since long fibres tangle permanently once they are rubbed. Use very little liquid and dry the rug with air moving under it as well as over it.

If it has just happened

Part the pile immediately and look at the base. On a long pile what you can see is the top of the mark and most of it has already run down the strands, so treating only the surface leaves the rest to dry underneath.

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.

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 blunt spatula The trade body names a blunt tool for lifting solids.
  • White cloths and white kitchen roll White only, so no dye transfers into the pile.
  • A bowl of warm water Warm, never hot. Hot water sets milk protein into the fibre.
  • White vinegar What this is Half and half with warm water is the trade body's method for vomit in carpet.
  • A vacuum For the powder afterwards, and for lifting the pile.

Helpful but not essential

  • Washing up liquid A single drop in the bowl, for the first pass.
  • Bicarbonate of soda For odour, once the visible mark has gone and the pile is dry.

Fresh baby sick on shaggy rug

Get underneath the pile straight away, because that is where it is going.

Go carefully with warm water

Shaggy rug tolerates warm 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 acidic cleaners

Shaggy rug tolerates acidic cleaners 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 off the surface

    Use a spoon and take off everything sitting on top before you disturb the pile, otherwise parting the strands drags it down into them.

  2. Part the pile and blot at the base

    Push the strands apart with your fingers and press white kitchen roll down onto the backing. This is the step people skip and it is the one that matters.

  3. Vinegar and warm water, on a cloth

    Equal parts white vinegar and warm water, dabbed on with a cloth at the base of the pile. Do not pour and do not spray, because a long pile absorbs far more than you intend.

  4. Blot out and dry with airflow underneath

    Press dry kitchen roll into the base. Then prop the rug so air can get under it, or hang it over a rail, and leave it until the backing is dry to the touch.

  • How longFifteen minutes
  • RepeatingBlot until a clean cloth stays clean at the base of the pile.
  • Stop ifthe base of the strands and the backing feel clean and barely damp

Dried baby sick on shaggy rug

Dried sick in a long pile is mostly solid, and solids come out mechanically.

Go carefully with warm water

Shaggy rug tolerates warm 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 acidic cleaners

Shaggy rug tolerates acidic cleaners only within limits. Keep contact time short, work from the edge of the mark inwards and stop if the material changes.

  1. Work the crust apart dry

    Hold the strands near the backing and break the dried material up with your fingers or a wide toothed comb. Most of it will fall out.

  2. Vacuum with the hose, not the beater bar

    A beater bar tangles long pile. Use the hose attachment and work in the direction the pile lies.

  3. Damp treatment at the base only

    Vinegar and warm water on a cloth, pressed into the base of the strands. Expect the smell to return while it is damp, so ventilate.

  4. Comb the pile out as it dries

    Separating the strands with your fingers while the rug dries stops them drying stuck together, which is what makes a matted patch.

  • How longTwenty minutes plus drying
  • RepeatingTwo passes, letting the rug dry in between.
  • Stop ifthe strands separate cleanly and nothing crusty is left at the base

Old or set in baby sick on shaggy rug

For an old mark, the dry route reaches further than the wet one.

Go carefully with machine washing

Shaggy rug tolerates machine washing only within limits. Keep contact time short, work from the edge of the mark inwards and stop if the material changes.

  1. Bicarbonate of soda worked into the base

    With the rug fully dry, sprinkle generously and work it down between the strands with your fingers. Leave it overnight.

  2. Vacuum it out from two directions

    Use the hose and go over the area twice, at right angles, so powder comes out of the base rather than being pushed along it.

  3. Check the label for machine washing

    Many synthetic shaggy rugs can go in a machine on a cool gentle cycle. If yours can, that reaches the backing in a way no spot treatment does. Air dry it flat afterwards and never tumble dry it.

  4. Restore the pile by hand

    Once dry, separate matted strands with your fingers and a wide toothed comb. Loft usually comes back if the fibres were not rubbed while wet.

  • How longOvernight, plus a wash if the label allows
  • RepeatingOne powder treatment, then consider washing it.
  • Stop ifthe smell has gone and the pile has recovered its loft, or you have washed it

What not to use on shaggy rug

  • Rubbing or scrubbing the pile

    Long fibres tangle around each other permanently when rubbed wet. The flat shiny patch that results is a texture change that shows more than the stain did.

  • A vacuum beater bar on the long pile

    A rotating brush wraps and tears long strands. Furniture manufacturers warn against rotary brush attachments on textiles for the same reason. Use the hose.

  • Soaking it or using a hire machine

    A long pile holds an enormous amount of water and dries from the top down, so the backing stays wet for days. That is how a rug starts to smell.

  • A hairdryer or a radiator to speed things up

    Milk protein sets with heat, and synthetic pile can shrink or glaze. Cool air moving under the rug does the job without either risk.

White compared with coloured shaggy rug

Most shaggy rugs are polyester or polypropylene, where the colour is in the fibre and unlikely to be lifted by cleaning. The visible risk is texture rather than colour: a rubbed or over wetted area mats into a flatter, shinier patch, and because the whole appeal of the rug is the loft of the pile, that shows more than a faint stain would.

Products that genuinely help here

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

    For the base of a long pile, where the mark actually is

    This is a spot cleaner formulated to be blotted back out rather than rinsed, which is the constraint that matters on anything that cannot be taken to a sink. WoolSafe approval means its alkalinity has been assessed as suitable for wool, so it is usable whether the fibre turns out to be wool or synthetic.

    Worth knowing. Apply it to a cloth and work it into the base of the strands. Sprayed on, a long pile absorbs far more than intended.

If the mark is still there

Check the backing before you decide it is done. Turn a corner up and feel underneath the affected area. If it is damp, the rug needs more drying time with air moving underneath it, not more cleaning.

Smell is the usual survivor here, because a long pile holds material at its base where nothing reaches. Once the rug is properly dry, work bicarbonate of soda down into the base of the pile with your fingers, leave it overnight and vacuum it out with the hose. That reaches further than any liquid will.

If a matted patch has formed, let it dry completely and then work the fibres apart with your fingers and a wide toothed comb. Some loft comes back. If the rug is machine washable, and many synthetic shaggy rugs are, a cool wash with the mark already treated is a better answer than repeated spot cleaning.

When to stop and call someone

Get a carpet cleaner in rather than continuing if the smell survives a dry bicarbonate treatment, if the backing has stayed damp for more than a day, or if a large area is matted. If the rug carries a machine washable label and fits in your drum, that is usually a better answer than a professional visit.

Why baby sick behaves this way on shaggy rug

A shaggy rug is a long, loosely packed pile, usually polyester, polypropylene or a wool blend, on a fabric backing.

The pile is a funnel

Liquid does not sit on a long pile, it runs down the strands and collects at the backing. The visible mark is the residue left on the way down. That is why treating the tips achieves very little and why the smell outlasts the stain.

Rubbing is the permanent damage

Long fibres tangle around each other when they are rubbed and they do not recover. The result is a flat, shiny patch with a different texture from the rest of the rug, which catches the light and reads as a mark. Blotting and finger combing are the motions that do not do this.

Drying is slow and matters

A thick pile on a fabric backing dries from the top down, and the base is last. Anything left damp at the base ferments, which is where a persistent sour smell comes from. Air underneath the rug is worth more than air over it.
