How to Clean Vomit: 7 Steps to Eliminate Stains and Odors

Because some messes are just too horrifying to ignore.

A girl holds her mouth and stomach trying not to vomit.

Vomit happens. Whether it’s from a sick child, an overly ambitious night out, or a car ride gone wrong, it’s never a fun mess to deal with. The smell alone is enough to make you consider just moving out. But don’t worry—with the right techniques, you can remove stains, neutralize odors, and restore your floors, furniture, and car upholstery to their former glory. Let’s get to work before the smell gets any worse.

Why Cleaning Vomit Quickly Matters

Vomit isn’t just disgusting—it’s also acidic and bacteria-filled, which means it can cause stains and lingering odors if left untreated. The longer it sits, the harder it is to remove. Quick action prevents permanent damage to fabrics, carpets, and hardwood floors while also reducing the risk of germs spreading.


What You’ll Need to Clean Vomit

Before diving into the mess, gather these supplies:

  • Rubber gloves – Because nobody wants this on their hands.
  • Paper towels or disposable rags – For initial cleanup.
  • Baking soda or cornstarch – Absorbs moisture and neutralizes odors.
  • White vinegar or hydrogen peroxide – Breaks down stains and kills bacteria.
  • Dish soap or enzymatic cleaner – Cuts through proteins and eliminates smells.
  • Microfiber cloths or sponges – For scrubbing without damaging surfaces.
  • Vacuum or dustpan – To remove dried residue.
  • Air freshener or essential oils – Helps get rid of lingering smells.

How to Clean Vomit in 7 Steps

1. Remove the Bulk of the Mess First

Put on rubber gloves and use paper towels or disposable rags to scoop up as much of the vomit as possible. If it’s on a hard surface, use a dustpan and wipe away the residue. For carpet or fabric, avoid scrubbing at this stage—it will only push the vomit deeper into the fibers.

2. Absorb Moisture with Baking Soda or Cornstarch

Sprinkle baking soda or cornstarch generously over the area. These powders soak up excess moisture, making the cleanup process easier while also helping neutralize the smell. Let it sit for at least 15 minutes before vacuuming or sweeping it away.

3. Treat Stains with Vinegar or Hydrogen Peroxide

For fabrics, carpets, or upholstery, mix equal parts white vinegar and water and blot the stained area with a cloth. If dealing with tough stains, use hydrogen peroxide, but test on an inconspicuous area first to ensure it doesn’t bleach the fabric. Avoid using hot water, as heat can set the stain.

4. Scrub with Dish Soap or an Enzymatic Cleaner

Apply a few drops of dish soap mixed with warm water and scrub the area with a microfiber cloth or sponge. If cleaning pet vomit, use an enzymatic cleaner, which breaks down organic material at a molecular level and removes lingering smells. Rinse with clean water and blot dry.

5. Disinfect and Deodorize

Once the stain is gone, spray the area with a mixture of white vinegar and water or hydrogen peroxide to kill any remaining bacteria. Let it sit for 5–10 minutes, then wipe clean. For extra freshness, add a few drops of essential oil to a spray bottle filled with water and lightly mist the area.

6. Dry the Area Completely

Damp carpets, upholstery, or hardwood floors can develop mold and mildew if they’re not dried properly. Use a fan, open windows, or place a towel over the spot to absorb remaining moisture. If cleaning a mattress, use a hairdryer on a low setting to speed up drying.

7. Prevent Future Smells and Stains

To keep your space fresh and stain-free:

  • Use waterproof mattress or couch covers to prevent deep stains.
  • Keep an emergency cleaning kit with baking soda, vinegar, and rags for quick cleanups.
  • Train pets to avoid problem areas where they tend to get sick.
  • Ventilate the room well to remove lingering odors.

How Professionals Handle Vomit Cleanup

For severe cases—like vomit in cars, deep carpets, or upholstery—professionals use:

  • Steam cleaners – High heat lifts deep-set stains and bacteria.
  • Ozone machines – Breaks down persistent odors at a molecular level.
  • Industrial-grade enzymatic cleaners – Used for deep sanitization.
  • Extraction vacuums – Removes liquid and bacteria from carpets and upholstery.

If the odor lingers after multiple cleanings, consider calling a professional cleaning service to fully remove the mess (deep carpet cleaning guide).


How Often Should You Clean Vomit-Stained Areas?

  • Immediately: The faster you clean, the better the results.
  • Reapply treatments as needed: If the stain or smell persists, repeat the cleaning process.
  • Deep clean carpets and upholstery every 3–6 months to maintain freshness.
  • Sanitize surfaces after cleaning to prevent lingering bacteria.

Final Thoughts

Cleaning up vomit is never fun, but with the right approach, you can remove stains and odors quickly and effectively. Acting fast, using the right cleaning agents, and ensuring proper ventilation will help you restore your space to its former freshness.
