The short answer

Blot without pressing and let a soft brush do the work in the hollows, because a wet embossed paper flattens under any pressure and the relief does not come back. Lift solids downwards with the flat of a blade. If the paper is painted, it behaves partly like the paint on it, which is usually matt emulsion and therefore not washable either.

If it has just happened

Blot straight onto the surface without pressing, and resist the urge to push a cloth into the texture. Pressure on damp embossed paper is what flattens it.

Avoid heat while treating the stain

Avoid adding heat while treating this stain. Follow the material's care instructions and the method below; heat may make a mark harder to remove or damage the material or its finish.

Test on a hidden area first

Use only a cleaner allowed by the material's care instructions. Test it on an inconspicuous area with the same material and finish, or a matching offcut. Let the test area dry and check for changes in colour, texture or finish 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 plastic scraper or the flat of a knife For lifting solids off a wall without gouging the surface.
  • Several white cloths or sponges White, soft, and wrung out hard. Damp rather than wet is the rule on every wall surface.
  • Warm water Warm, not hot. Heat sets milk protein and softens wallpaper paste.
  • A dry towel For drying the area immediately, which matters more on a wall than almost anywhere.

Helpful but not essential

  • Washing up liquid A drop in the water. Paint makers specify a non bleach based cleaner such as this.

Fresh baby sick on textured wallpaper

Blot downwards, damp not wet, and dry it straight away.

  1. Lift the solids off first

    The flat of a knife or a plastic scraper, drawn downwards and away from the wall rather than pressed into it. Catch what falls with kitchen roll held below.

  2. Blot the run downwards

    Press a dry cloth onto the mark and lift. Work down the wall, because anything that runs lands on an area you are about to treat rather than on clean wall below.

  3. Then a barely damp cloth

    Wrung out hard. Damp rather than wet is the rule on every wall surface, painted or papered, and it is what stops a tide line forming.

  4. Dry the area immediately

    Blot the area dry without pressing and leave it. Slight flattening sometimes recovers as the paper dries, and pressing it while damp guarantees it will not.

  • How longTen minutes
  • RepeatingBlot until nothing more transfers.
  • Stop ifnothing more transfers to a clean cloth and the wall has been dried

Dried baby sick on textured wallpaper

Softening and patience, and stopping before the surface burnishes.

  1. Brush or scrape the loose material away dry

    A soft brush or the flat of a blade takes off anything sitting proud, and it carries no risk of spreading the mark.

  2. Hold a damp cloth against it to soften

    A minute or two, without rubbing. Dried milk on a painted or papered surface softens and lifts rather than needing force.

  3. Wipe gently downwards, then dry

    Light pressure, one direction. Watch the surface as you go: if it starts to look shinier than the wall around it, stop, because that is burnishing and it is permanent.

  4. Feather the edge outwards

    Work the damp cloth outwards from the treated area so there is no hard boundary where the damp stopped.

  • How longTwenty minutes
  • RepeatingTwo gentle passes, then stop.
  • Stop ifthe mark has lifted, or two passes have not moved it and the surface is starting to shine

Old or set in baby sick on textured wallpaper

On a wall, the honest last step is usually paint rather than cleaner.

  1. Decide whether it is a stain or damage

    A mark that has not moved after two gentle passes is either in the surface or has burnished the area around it. More cleaning makes the second one worse.

  2. Let it dry completely and look again

    Walls look far worse damp, and a mark that seems obvious while wet is often invisible the next day in normal light.

  3. Seal before repainting, not after

    Building conservation practice is that a stain will bleed through fresh paint unless it is sealed first, and that a white pigmented shellac primer blocks it. Painting straight over a stain usually means painting it twice.

  4. Prime the whole wall, not the patch

    The same guidance notes that spot priming leaves visible shiny patches with standard paints. On a wall, the unit of repair is the wall.

  • How longAn hour, then a decision
  • RepeatingDo not keep working the same patch.
  • Stop ifthe mark has faded as far as it will, or the wall needs sealing and repainting

What not to use on textured wallpaper

  • Working upwards

    Water runs down a vertical surface and a drip onto dry wall below leaves a visible streak. Wallpaper guidance is specific about this: clean downwards so any run lands on an area you are about to treat.

  • Using a wet cloth rather than a damp one

    Excess water on a wall runs, soaks into plaster, activates wallpaper paste at the seams and leaves a tide line at the edge of the wet area. Wring the cloth until it is barely damp.

  • Scrubbing, or using an abrasive sponge

    Paint and wallpaper both burnish, which means the scrubbed area goes shinier than the surface around it. That shows in raking light and it is permanent short of repainting.

  • Bleach based cleaners

    Paint manufacturers specify a non bleach based cleaner. Bleach lightens paint colour unevenly and on wallpaper it strips the print.

  • Pressing a cloth into the texture

    Damp embossed paper flattens under pressure and the relief does not return. A flat patch in a textured wall is far more visible than a faint shadow.

  • A brush with any stiffness on woodchip

    The chips lift out of the paper and leave bare patches, which cannot be repaired without replacing the drop.

White compared with coloured textured wallpaper

Painted textured papers are usually white or a pale colour, so a shadow shows. Crushing shows more: a flattened area of anaglypta or woodchip reads as a patch from across the room because the texture is the whole pattern. Given the choice between a faint mark and a flat patch, the mark is much the better outcome.

If the mark is still there

Let it dry fully and then look at the relief rather than the colour. Slight flattening sometimes lifts as the paper dries, and there is nothing to be gained by intervening while it is damp.

If the paper is painted, a fresh coat over the whole wall hides a surprising amount, because the texture scatters light and disguises a shadow underneath. That is usually the cheapest acceptable repair.

If the relief has been crushed, or woodchip has lifted or blistered, no cleaning corrects it and the drop needs replacing. Textured papers are usually inexpensive, which makes that more realistic than it sounds.

When to stop and call someone

Get a decorator involved rather than continuing if the relief has been crushed flat, which cannot be restored, or if woodchip or embossed paper has lifted or blistered. On painted textured paper, repainting the wall hides a good deal, and that is usually the cheapest acceptable answer.

Why baby sick behaves this way on textured wallpaper

Textured wallpapers are embossed papers and relief vinyls, generally painted after hanging.

The embossing is fragile when wet

The pattern is pressed into the paper, and wet fibres flatten under any pressure and stay flat. That is the specific damage to avoid here.

The texture holds the spill

Relief patterns have hollows a flat cloth passes straight over, which is why blotting and a soft brush reach what wiping does not.

Paint changes the surface

A painted anaglypta behaves partly like the paint on it, which is normally matt emulsion, with all of matt's limitations about pigment lift and burnishing.

Woodchip is the difficult case

Paper with wood chips in it absorbs, swells and lifts, and it is close to impossible to clean without damage.
