How do I clean up vomit properly?
Two separate jobs: lifting the material without spreading it, and disinfecting properly afterwards, because the virus is what makes the rest of the household ill.

Short answer
Gloves on, solids lifted with paper or cardboard, area covered with bicarbonate of soda to absorb the rest, then vacuum or scrape and disinfect with a chlorine product. Never use hot water first — the protein sets and the smell is locked in.
Cleaning up vomit is treated as an unpleasant chore when it is really an infection control task. Norovirus spreads through aerosolised particles thrown up during cleaning and survives on carpet and upholstery for days. The order of work matters as much as the products.
Safety
What you'll need
- Disposable gloves
- Paper towels, newspaper or cardboard
- Bicarbonate of soda
- A chlorine-based disinfectant
- A bin bag
Step by step
- Open a window and put gloves on.Ventilation reduces airborne particles and helps the smell. Gloves are not squeamishness — norovirus transfers readily to hands.
- Lift the solids without pressing.Slide a piece of card or a stack of paper towels underneath and lift. Wiping presses material into carpet pile or upholstery where it cannot be recovered.
- Bag the waste immediately.Straight into a bin bag, tied, and out. Leaving it in the room in an open bin keeps the smell and the virus circulating.
- Cover the remaining area with bicarbonate of soda.A thick layer, left twenty minutes. It absorbs the moisture and a good deal of the smell, and it turns a wet mess into something that can be vacuumed or scraped.
- Use cold water only for the first clean.Vomit is protein. Hot water cooks it into the fibre and permanently sets both the stain and the odour.
- Blot rather than rub, from the outside in.A cloth wrung out in cold water with a little washing-up liquid, pressed and lifted. Working inwards keeps the area from growing.
- Disinfect with a chlorine-based product.This is the step that actually protects the household. Follow the dilution on the label and leave the contact time it specifies. Alcohol gel and ordinary detergent do not kill norovirus.
- Treat the residual smell with an enzyme cleaner.After disinfecting and once dry. Enzymes digest the protein residue that is producing the smell, which is why masking sprays never work here.
- Wash textiles hot, separately.Sixty degrees or above for bedding and clothing, on their own, with a full-length cycle. Contradicting the cold-water rule is correct at this stage because the virus matters more than the stain.
- Wash your hands with soap and water.Not hand gel. Norovirus has no envelope for alcohol to break down, so soap, friction and running water are what remove it.
Tips
- Keep a cheap cleaning kit — gloves, bicarbonate, paper towels, bin bags, a chlorine cleaner — together in one box. Assembling it while standing over the mess is the worst time.
- Vomit on a mattress needs the absorbent step done twice rather than water added. Soaking a mattress creates a mould problem that lasts far longer than the stain.
- The person cleaning is the one most likely to catch it. Gloves, ventilation and hand washing matter more than any product choice.
Common mistakes
- Reaching for hot water and a steam cleaner — Heat sets the protein into carpet fibres permanently, and steam aerosolises virus particles across the room. Cold and absorbent first, disinfectant second.
- Assuming an ordinary cleaner has disinfected it — Most household sprays and all alcohol gels are ineffective against norovirus. A chlorine-based product at the correct dilution and contact time is what stops the rest of the house catching it.
If it doesn't work
Smell returns when the room warms up
Cause: Residue left deeper in the pile or padding — Fix: Enzyme cleaner applied generously enough to reach as far as the original material did, left to work, then blotted and dried thoroughly.
Stain lightened but a yellow mark remains
Cause: Stomach acid has affected the carpet dye — Fix: Often permanent. Try an oxygen-based carpet treatment once; if the dye has been stripped, the fix is a repair rather than a clean.
Others in the house become ill days later
Cause: Virus survived on surfaces and hands — Fix: Disinfect door handles, taps, flush handles and light switches with a chlorine product, and wash hands with soap rather than gel for a fortnight.
Damp patch that will not dry
Cause: Too much water used during cleaning — Fix: Press dry towels down with body weight, then a fan or dehumidifier on it until fully dry. Damp carpet padding grows mould within days.
Questions people ask
How long does norovirus survive on a carpet?
Up to two weeks on hard and soft surfaces. That is why a proper disinfection step matters even when the visible mess has gone completely.
Can I steam clean the carpet afterwards?
Yes, but only after the material has been removed and the area disinfected. Steam applied to fresh vomit sets the protein and spreads particles into the air.
What about a car seat?
Same sequence, but be careful with chlorine products on automotive fabric and leather — test first, and use an enzyme cleaner for the smell, which is the part that lingers in a hot car.
