How to Get Vomit Out of a Cotton Rug

Getting vomit out of a cotton rug is very doable at home with the right order of steps. The short version: cold water only, mild detergent, then an enzyme cleaner to break down what blotting cannot lift. Cotton Rug is forgiving, so the main thing is method and order, not caution.

What you’ll need

Step-by-step method

1. 1

   Cotton rugs run their dyes and shrink in heat, so test first: dab a hidden corner with your cleaning solution on a white cloth and check for colour lifting before you touch the vomit.

2. 2

   Scrape and lift all solids with a spoon or blunt knife, working from the outside in. Open a window — you will be down there a while.

3. 3

   Dab the area with COLD water on a white cloth and keep blotting dry. Cold is not optional: any warmth cooks the protein onto the fibre.

4. 4

   Mix a teaspoon of mild detergent into 500 ml of cold water, dab it on, and blot. Repeat until no more transfers to the cloth.

5. 5

   For any remaining mark, apply an enzyme-based stain remover and leave it to work for the time on the label — usually around 10 minutes.

6. 6

   Blot the area dry with fresh cloths, dab with plain cold water to rinse, and blot again.

7. 7

   Leave to air dry away from radiators and sunlight, then vacuum.

8. 8

   If the rug is a flatweave or rag rug and its label allows it, a cool 30-degree machine wash on a gentle cycle often finishes a vomit that spot-cleaning only lightened — but check for a latex or foam backing first, which must never be tumble-dried.

9. 9

   Dry the rug flat and fully before it goes back down; a damp rug left on the floor traps moisture against both surfaces.

Why this works

Don’t do this on a cotton rug

• Never use warm or hot water on vomit — heat coagulates protein and sets the stain permanently.
• Never use a steam cleaner before the stain is fully out, for the same reason.
• Work quickly: stomach acid can bleach some carpet dyes if left, and no cleaning reverses colour loss.
• Never use hot water on a cotton rug — cotton shrinks and fugitive dyes run at temperature.
• Never use chlorine bleach on a coloured cotton rug; the dye goes with the stain.
• Test for colour fastness on a corner every time, even on an old rug — printed cottons bleed the most.

Fresh spill vs dried-in stain

Deal with vomit as fresh as you can bear to: stomach acid starts bleaching and etching some dyes within the hour. Once dried, the protein residue needs an enzyme cleaner and the acid may have left permanent colour change no cleaning will reverse.

A dried protein stain needs the enzyme cleaner from the start and possibly two or three cycles. Rehydrate the mark with cold water first so the enzymes can reach the protein.
