The short answer

Wipe the surface with a barely damp cloth and dry it immediately. A veneer is a very thin slice of real wood glued to a board, often less than a millimetre, and water reaching the adhesive softens it so the veneer bubbles and lifts. Pay particular attention to edges and lippings, which are where liquid gets underneath, and never sand a veneer, because sanding goes straight through it.

If it has just happened

Wipe it and dry it. On veneer the whole job is over in a minute, and everything after that is about not letting liquid sit at an edge.

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 Plastic, so a finish is not scored. Metal marks wood and vinyl alike.
  • Kitchen roll For lifting the bulk before any water is involved. On a floor this matters more than anywhere.
  • A well wrung cloth or microfibre mop Damp, never wet. Every flooring manufacturer in this family says the same thing.
  • Warm water Warm rather than hot, and as little of it as the job allows.
  • A dry towel For drying the floor immediately afterwards, which is part of the method rather than tidying up.

Helpful but not essential

  • Washing up liquid A drop, where the floor allows it. Some finishes want a specific cleaner instead.

Fresh baby sick on wood veneer

Get it up before it reaches a joint. That is the whole of the fresh method on any floor.

Go carefully with warm water

Wood veneer tolerates warm 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 with a plastic scraper

    Plastic rather than metal, and lifted rather than pushed, because pushing spreads a spill across more joints.

  2. Blot the liquid up before you clean anything

    Kitchen roll pressed down hard. Every millilitre taken up dry is one that cannot find a seam.

  3. Then clean with a well wrung cloth

    A barely damp cloth with a drop of washing up liquid, wiped over the surface and kept away from the edges and lippings.

  4. Dry the floor immediately

    Dry the surface immediately and check along it at a low angle the next day for any bubbling or lifted edge.

  • How longTen minutes
  • RepeatingBlot until nothing more transfers.
  • Stop ifthe floor is clean and dried, with nothing left standing in a joint

Dried baby sick on wood veneer

Soften it rather than scraping it, and keep the water to a minimum while you do.

Go carefully with warm water

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

  1. Soften the crust with a damp cloth

    Lay a barely damp cloth over the mark for a few minutes. Dried milk lifts off a finished floor once it is soft, and scraping at it damages the finish.

  2. Work it gently with a soft cloth or brush

    Along the grain on wood, and in one direction on a smooth floor. No abrasive pads.

  3. Clean the area and a little beyond it

    A barely damp cloth with a drop of washing up liquid, wiped over the surface and kept away from the edges and lippings.

  4. Dry it and check the joints

    Dry the surface immediately and check along it at a low angle the next day for any bubbling or lifted edge.

  • How longTwenty minutes
  • RepeatingTwo passes, drying between them.
  • Stop ifthe residue has lifted and the floor is dry, with no swelling at a joint

Old or set in baby sick on wood veneer

By now the question is whether the finish or the board has been affected rather than the surface.

Go carefully with warm water

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

  1. Work out what you are looking at

    A mark on the finish sits on top and responds to cleaning. A mark in the timber has gone through a break in the finish and does not. A raised or swollen edge is water damage and is a different problem again.

  2. Try the finish specific product

    Oiled and waxed floors have maintenance products made for them, and a stubborn mark on those needs the liquid wax cleaner rather than the ordinary wash. Lacquered floors have their own cleaner.

  3. Look at the joints and edges

    Swelling at a board edge, a lifted lip or a dark line along a seam means water got in. That is not going to improve with cleaning and it tells you where to stop.

  4. Then get a floor specialist to look

    On a solid or engineered wood floor, sanding and refinishing an area or a room is a normal job. On a floor with a wear layer, replacing a board or a plank is the equivalent.

  • How longHalf an hour, then a decision
  • RepeatingDo not keep wetting the same area.
  • Stop ifthe mark has gone, or the finish or the board itself needs attention

What not to use on wood veneer

  • A steam cleaner or steam mop

    Wood, laminate, linoleum and vinyl flooring makers all exclude steam. It forces moisture into joints and lower layers and causes swelling and warping, and the heat sets milk protein at the same time.

  • A wet mop, or leaving water standing on the floor

    Excess moisture goes into the joints, and on every floor in this family the joint is the vulnerable part. Damp and wrung out, then dried, is what the manufacturers specify.

  • Abrasive pads, scouring powders and wire wool

    They cut through a finish or a wear layer, and on a floor that damage then absorbs everything and spreads. On LVT the wear layer cannot be refinished at all.

  • Ammonia based and strong alkaline cleaners

    Flooring makers name ammonia specifically. It dulls and degrades wood finishes and vinyl wear layers, and strongly alkaline cleaners damage linoleum.

  • Sanding a veneer

    It is usually under a millimetre thick and sanding goes straight through to the board underneath, which cannot be repaired. This is the one surface here where sanding is completely excluded.

White compared with coloured wood veneer

Veneered surfaces are chosen for their figure, so a mark shows against a pattern that draws the eye. What shows far more is a bubble: a lifted area catches light differently and the raised edge is visible from across a room. Since sanding is not available on a veneer, the finish over it is the only thing that can be restored, which limits what can be done about a mark in the wood itself.

If the mark is still there

Look along the surface at a low angle a day later. A bubble or a lifted edge shows that way well before it is obvious from above.

If the veneer has lifted, do not press it and hope. Refixing a veneer needs adhesive worked underneath and then cramping or weighting while it sets, which is a furniture restorer's job and a routine one for them.

If the mark is on the finish rather than in the veneer, a furniture polish or a light recoat may deal with it. If it has gone into the wood, the options are limited, because the usual answer of sanding is not available on a layer this thin.

When to stop and call someone

Get a furniture restorer involved rather than continuing if the veneer has bubbled or lifted, because pressing it back needs adhesive and cramping. Do not sand a veneer under any circumstances, since it is usually less than a millimetre thick and sanding goes straight through to the board.

Why baby sick behaves this way on wood veneer

Wood veneer is a thin slice of real timber bonded to a substrate.

It is thinner than people expect

Modern veneer is often under a millimetre. That is enough for the appearance of solid timber and nowhere near enough to sand.

The glue line is the failure point

Water softens the adhesive and the veneer bubbles and lifts. Pressing it back without adhesive and pressure does not work.

The edges are exposed

Veneered panels have lippings or edge banding, and those joints are the way underneath.

The substrate swells

Usually MDF or chipboard, so whatever gets past the veneer meets a material that expands and pushes the veneer further off.
