The short answer

Wipe the spill up and clean with a well wrung mop and warm water. Sheet vinyl is impermeable and has very few joints, which makes it the most water tolerant floor in this family. The seams between sheets and the edge where the vinyl meets a skirting or a threshold are the only routes underneath, so keep water away from those and dry the floor afterwards.

If it has just happened

Wipe it up and check where the run ended. On sheet vinyl the middle of the floor looks after itself and the edges do not.

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 vinyl flooring

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

Go carefully with warm water

Vinyl flooring 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 well wrung mop with warm water and a neutral floor cleaner, kept away from the seams and the room edges.

  4. Dry the floor immediately

    Dry the floor and check the seams and the perimeter afterwards for any lifting or dark line.

  • 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 vinyl flooring

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

Go carefully with warm water

Vinyl flooring 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 well wrung mop with warm water and a neutral floor cleaner, kept away from the seams and the room edges.

  4. Dry it and check the joints

    Dry the floor and check the seams and the perimeter afterwards for any lifting or dark line.

  • 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 vinyl flooring

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

Go carefully with warm water

Vinyl flooring 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 vinyl flooring

  • 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.

  • A hard scraper on cushioned vinyl

    The foam backing compresses permanently, so a scraper leaves a dent that stays after the mark has gone. Soften a dried mark with warm water instead.

White compared with coloured vinyl flooring

Vinyl flooring is a printed layer under a clear wear layer and it does not stain, because nothing reaches the print. What does show is damage to the wear layer from abrasives, which dulls it and eventually exposes the print, and on cushioned vinyl a dent from a hard scraper, because the foam backing compresses permanently.

If the mark is still there

Look at the seams and the perimeter once the floor is dry. A lifted seam or a dark line at the edge means water got to the backing.

If the mark itself is still there, a second pass with warm water and a neutral cleaner will deal with it. There is nothing in vinyl for a stain to occupy.

If the vinyl has blistered or lifted, that is not repairable in place. Sheet vinyl is welded or bonded, and a fitter can weld a patch or replace the sheet, which is the point at which it stops being a cleaning job.

When to stop and call someone

Get a flooring fitter in rather than continuing if a seam has lifted, if the vinyl has blistered where water reached the backing, or if the wear layer has been worn through. Sheet vinyl is not repairable in place, so the fix is a new sheet or a welded patch by someone who does that work.

Why baby sick behaves this way on vinyl flooring

Sheet vinyl is a printed layer under a clear wear layer, on a felt or foam backing.

The sheet is impermeable

Which is why it is specified for kitchens and bathrooms and why it handles a spill better than almost anything else here.

The joints are few and decisive

Seams between sheets, and the edge where the vinyl meets a skirting or a threshold. Water there reaches the backing and the subfloor, which is where a blister or a lifted patch comes from.

The wear layer is finite

Abrasives cut through it and expose the printed layer, which then wears off. That cannot be refinished.

Cushioned vinyl dents

The foam backing compresses permanently, so a hard scraper leaves a dent as well as a mark.
