The short answer

Blot the liquid up immediately, because parquet has many times the joint length of a plank floor and a spill finds a seam within seconds. Clean with a barely damp cloth and dry the floor straight away. If the parquet is old, the blocks are probably bedded in bitumen, which softens when it gets damp, and a lifted or rocking block is a specialist repair rather than a clean.

If it has just happened

Blot it up fast. On parquet the spill is already at a joint by the time you have found a cloth, so speed buys more here than on any other wood floor.

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 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 parquet

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

Go carefully with warm water

Parquet 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 wood floor cleaner, worked over the blocks rather than into the joints between them.

  4. Dry the floor immediately

    Dry the floor immediately with a towel and press the affected blocks afterwards to check none has begun to move.

  • 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 parquet

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

Go carefully with warm water

Parquet 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 wood floor cleaner, worked over the blocks rather than into the joints between them.

  4. Dry it and check the joints

    Dry the floor immediately with a towel and press the affected blocks afterwards to check none has begun to move.

  • 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 parquet

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

Go carefully with warm water

Parquet 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 parquet

  • 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.

  • Wet mopping a parquet floor

    Old parquet is bedded in bitumen that softens when damp, and the joint density means water reaches it quickly. A released block is a specialist repair.

White compared with coloured parquet

Parquet is usually a warm mid brown and the pattern itself disguises a faint mark well, which is worth remembering before working too hard on one. What the pattern does not disguise is a patch where blocks have moved or where the finish has been dulled, because the eye follows the geometry and any irregularity in it stands out.

If the mark is still there

Let it dry and then press the affected blocks with a foot. A block that rocks or clicks has released from its bedding, and that is the sign that liquid reached the adhesive.

If a mark is on the finish, a second gentle pass with the right wood floor cleaner deals with it. If it is in the wood, sanding is the answer, and solid parquet sands very well.

Do not attempt to refix a lifted block with ordinary adhesive. Parquet blocks are bedded in a specific way and a badly refixed block sits proud, which is far more noticeable on a patterned floor than a stain would be.

When to stop and call someone

Get a parquet specialist in rather than continuing if any block has lifted or rocks underfoot, if the floor is old and bedded in bitumen, or if a mark has gone into the wood. Refixing blocks and sanding parquet are specialist jobs and a badly done repair on a patterned floor is very visible.

Why baby sick behaves this way on parquet

Parquet is small wood blocks laid in a repeating pattern.

The joint length is the whole issue

Herringbone has an enormous amount of seam for the area it covers, so everything true of joints on a wood floor is multiplied.

Bitumen is the traditional bedding

A black adhesive that softens with moisture and heat. Water at a joint reaches it and the block releases, which shows as movement underfoot before it shows as a gap.

Blocks move independently

A wetted area can end up slightly uneven rather than evenly cupped, which catches the light across the pattern.

It sands well

Solid parquet has real thickness, and a sanded parquet floor is one of the better outcomes in flooring, which raises the value of getting a specialist rather than living with a mark.
