How to Remove Vomit Stains and Smell from Carpet
Cleaning vomit from carpet requires removing the physical material, treating the stain, and eliminating the odour — which is caused by stomach acid and partially digested food proteins. Skipping any step leaves residual odour that can be detectable for weeks.
Immediate Action
- Remove as much solid material as possible using a spoon or paper plates — scoop from the outside of the spill inward, not the other way, to avoid spreading. Do not press the material deeper into the carpet.
- Blot up as much liquid as possible with paper towels — press firmly and lift, replacing saturated towels.
- Sprinkle baking soda liberally over the affected area — the baking soda absorbs remaining moisture and neutralizes the acid. Allow 10–15 minutes.
- Vacuum up the baking soda thoroughly.
Stain Treatment
- Apply white vinegar (diluted 1:1 with water) to the stain and allow 5 minutes — the acid in vinegar neutralizes the alkaline residue and helps lift the stain
- Blot with clean cloths
- Apply dish soap solution (a few drops in cold water) and blot
- Rinse by blotting with cold water and blot dry
Odour Elimination (Critical Step)
Standard cleaning removes the visible stain but not the odour-causing proteins. An enzyme cleaner is required for complete odour removal:
- Apply an enzyme cleaner (Nature's Miracle, Folex, Rocco & Roxie, or similar) generously to the entire affected area and a 2-inch border beyond the visible stain
- Allow 15–30 minutes dwell time
- Blot with a clean cloth
- Allow to dry completely — assess the odour after the area is fully dry, as residual odour can be undetectable until completely dry but then detectable again
- If odour remains: apply enzyme cleaner again and cover the area with a clean cloth to prevent drying too quickly (longer dwell time improves effectiveness)
What Not to Use
- Hot water: sets protein stains
- Bleach on carpet: damages fibres and causes discolouration
- Masking sprays and air fresheners: cover the smell temporarily but don't eliminate the source — the odour returns
