How to clean vomit from carpet

What to check before you start

• How long it's been there: still wet, found soon after, or already dry
• Your carpet's care label or manufacturer guidance, including what it's made from — if it's wool, or you're not sure, take extra care
• Whether anything has already been used on the mark, and what
• A small, hidden area to try things on first
• Clean white cloths or paper towels, and a spoon or blunt edge for lifting solids
• If the vomit may be linked to an illness, hygiene can involve more than removing the visible mark. Follow current health guidance rather than relying on this cleaning guide for infection-control advice.

This applies whether the vomit came from a person or a pet. If it's urine rather than vomit, our guide on dog urine smell on carpet is the more direct one. If it has also reached a sofa, a mattress or a car seat, those are covered separately in how to clean vomit from a sofa, how to clean vomit from a mattress and how to clean vomit from a car seat.

If the vomit is still wet

1. Lift the solids firstUse a spoon, card or paper towels to scoop up solid pieces. Lift rather than press, so nothing is pushed further into the pile.
2. Blot up the liquid, without rubbingPress clean, dry cloths onto the wet area, using a fresh part each time. Rubbing can spread the mark and disturb the pile.
3. Pause before adding anythingOnce you've lifted and blotted what you can, check your carpet's guidance before adding water or cleaner. Extra moisture can leave the area wetter without shifting what's left.

If you've found it later, or it has dried

The longer vomit is left, the harder a mark generally is to shift, so it's worth acting as soon as you find it. Whether you find it hours later or once it has dried, the first move is the same: lift what you can before doing anything else.

If it has dried, don't treat it as a fresh spill. Start by lifting what will safely come away dry — flakes or a crust that lifts with a spoon or blunt edge, without pulling at the pile — and remove loose dry pieces before any moisture goes on. Whether vacuuming suits your carpet depends on the carpet.

Only then think about moisture, and only a little: a slightly damp white cloth pressed onto what's left is more controlled than pouring or spraying liquid onto the carpet. If the carpet is wool, or you're unsure, check its guidance first.

Treating the mark that's left

Once the solids are lifted and the liquid blotted, what's left is a damp patch and possibly a mark. Check your carpet's care label or manufacturer guidance before treating it: what's safe depends on the fibre, and a cleaner that suits one can damage or discolour another.

The clearest published guidance for vomit on carpet comes from WoolSafe, which writes care guidance for wool carpets. For wool, its spot-removal guide lists scooping up solids and blotting, applying a spot remover approved for wool to a damp white cloth rather than straight onto the carpet, rinsing by blotting with clean water, then drying the area and aligning the pile. That is specific to wool and shouldn't be assumed to apply to every fibre. If your carpet is something else, or you're not sure, your own care guidance comes first.

Whatever you use, try it on a small, hidden area first and check the result once it has dried. Use small amounts on a clean white cloth, working from the edge of the mark towards the centre, then blot with clean water to lift residue and blot as dry as you can. Avoid soaking the area: WoolSafe's guidance for wool warns that over-wetting lengthens drying time and may discolour the pile.

Vinegar, bicarbonate of soda (baking soda) and hydrogen peroxide are often recommended online, and hot water or steam suggested too. None is established as suitable for every carpet, and they aren't part of WoolSafe's steps for vomit on wool. Some can affect colour or fibre, so if you're considering one, check it against your carpet's guidance, try it on a hidden area first, and don't combine products.

If it's still there once it's dry

Judge the result once the carpet is fully dry, since a mark can look different dry. If a mark is still visible after one careful attempt, that's a different situation from a fresh spill, and a guide to old or resistant stains will help more than repeating the same steps — see Related guides below.

If a smell of sick is still there once it's dry, don't assume the cause from the smell alone: it can have more than one explanation, including how dry the carpet really is and what was used to clean it. That's covered separately — see Related guides below.

If a substantial amount of liquid soaked in, the problem may not be limited to the fibres you can see. That's a possibility, not something a smell or a mark can confirm, and it's a reason to stop repeated treatment and consider having the carpet looked at by a professional cleaner.

When to stop adding cleaner or water

Stopping isn't giving up. Each round of water and cleaner adds moisture, and past a point another attempt can do more harm than good — by keeping the area damp, leaving residue behind, or affecting the carpet itself.

Pause if the area is getting wetter rather than drier with each attempt, or if careful, repeated treatment isn't improving the result. Repeating the same approach isn't guaranteed to change the outcome.

Pause if you're not sure what the carpet is made from, or what has already been used on it, because further treatment is then harder to judge safely.

Pause if the affected area is larger, or has soaked in further, than a simple spot treatment reasonably deals with. At that point a professional opinion is usually more useful than another attempt.

Do you need a spot cleaner or carpet machine?

For a small, fresh or localised problem that responds to careful lifting, blotting and a suitable treatment, a machine isn't necessarily needed. Start with the least you can do and reassess once it's dry.

A spot cleaner may be worth considering where the problem is localised, your carpet's guidance allows it, and you can control how much moisture goes in. These machines add water as well as removing it, so over-wetting remains a risk.

Deeper extraction or a professional clean is more likely to be worth considering when a larger area has soaked in, careful treatment hasn't worked, or the problem seems to go beyond a simple surface spot. That doesn't make it always the better choice: it depends on the carpet and how far the problem has reached. If the material is uncertain, or you've already treated it more than once, a professional opinion is a reasonable next step.

If you want to understand what different cleaning machines actually do before considering one, our equipment guide covers what they do and when they may or may not help, and carpet cleaner vs spot cleaner compares the two most common types.
