The short answer

Wipe it up straight away and clean with a barely damp cloth, then dry the worktop. The oil finish is what makes a wooden worktop water resistant, and detergent strips it, so a cleaned patch absorbs the next spill. Re-oil the area afterwards. If the sickness came with a stomach bug, disinfect after cleaning and before re-oiling, and dry the surface completely.

If it has just happened

Wipe it up immediately. A wooden worktop is protected only by the oil in its surface, and standing liquid gets past that quickly.

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 butcher block worktop

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

Go carefully with warm water

Butcher block worktop 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 little washing up liquid, worked along the grain, then rinsed with a clean damp cloth.

  4. Dry the floor immediately

    Dry the worktop thoroughly with a towel and then re-oil the area, because the cleaning has taken oil out of the surface.

  • 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 butcher block worktop

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

Go carefully with warm water

Butcher block worktop 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 little washing up liquid, worked along the grain, then rinsed with a clean damp cloth.

  4. Dry it and check the joints

    Dry the worktop thoroughly with a towel and then re-oil the area, because the cleaning has taken oil out of the surface.

  • 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 butcher block worktop

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

Go carefully with warm water

Butcher block worktop 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 abrasive scrubbing

Butcher block worktop tolerates abrasive scrubbing 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 butcher block worktop

  • 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.

  • Leaving standing water on it, particularly near a sink cut out

    Water opens the glue lines between staves and darkens the timber. A wooden worktop is dried after every wetting, not left to evaporate.

White compared with coloured butcher block worktop

Oiled hardwood darkens where it has taken up moisture and lightens again as it dries, which is normal. A patch that stays lighter and drier looking has lost its oil, and one that stays dark has taken water into the timber. The first is fixed by re-oiling, the second by sanding and re-oiling, and telling them apart takes a day of drying.

If the mark is still there

Re-oil the area once it is dry. That is not an optional finishing touch: it is what restores the water resistance that cleaning removed, and a wooden worktop that is not re-oiled after cleaning develops dark patches around the sink within months.

If a dark mark has gone into the timber, sand the area lightly with the grain, working out to a natural boundary such as a joint or an edge, and then re-oil generously. Solid wood worktops are thick enough that this can be done many times.

Check the glue lines between the staves, particularly around a sink or hob cut out. An open joint takes water every time the tap runs and it needs a fitter rather than more oil.

When to stop and call someone

Sand and re-oil the area rather than calling anyone, which is normal maintenance on a wooden worktop and well within a competent afternoon. Get a fitter involved if a glue line between staves has opened, particularly around a sink cut out, because that lets water into the joint every time the tap runs.

Why baby sick behaves this way on butcher block worktop

A butcher block worktop is hardwood staves glued edge to edge and finished with a food safe oil.

The oil is the water resistance

It penetrates the surface and keeps liquid out. Detergent strips it, and a stripped patch absorbs, darkens and marks. Re-oiling after cleaning is normal practice rather than a repair.

The glue lines are the weak spots

Standing water, particularly around a cut out, opens the joints between staves.

It is a food surface

So the same order applies as on a chopping board: clean, then disinfect if the sickness was infectious, then dry completely, then re-oil.

It sands

Which makes even a deep mark recoverable, and is the main advantage of solid wood over a laminate.
