How To Get Rid Of Vomit Smell In Mattress: Step‑by‑Step FAQ Guide

If you’re searching for “How To Get Rid Of Vomit Smell In Mattress,” you’re likely dealing with an accident that left both a stain and a stubborn odor. This guide walks you through what to do, which cleaners to use, and how to keep your mattress fresh without damaging it.

Why does vomit smell linger in a mattress?

Mattresses are thick and absorbent. When vomit soaks in, liquids, food particles, and stomach acids can:

  • Sink below the surface layer
  • Get trapped in foam and fabric
  • Start to break down and produce strong, long-lasting odors

If the area isn’t cleaned quickly and thoroughly, the smell can return even after the top looks clean.

First steps: What should I do right away?

1. Remove bedding
Strip sheets, mattress protectors, and blankets. Wash them according to their care labels with a normal detergent and, if allowed, warm or hot water.

2. Blot, don’t rub
Use paper towels or a clean cloth to blot up as much liquid as possible. Avoid scrubbing, which can push vomit deeper into the mattress.

3. Ventilate the room
Open windows or use a fan to help reduce the smell and speed up drying.

What’s the best way to clean fresh vomit from a mattress?

For fresh stains, a simple home method is usually enough:

  1. Mix a mild cleaning solution

    • Combine a small amount of gentle liquid soap with cool or lukewarm water.
    • Avoid soaking the mattress; use just enough to dampen the area.

  2. Spot clean the stain

    • Dip a clean cloth into the soapy water.
    • Gently dab the stained area, working from the outside in.
    • Blot with a dry cloth to remove moisture after each pass.

  3. Use an odor-fighting solution
    Many people find a white vinegar and water mixture helpful for neutralizing odor:

    • Mix equal parts white vinegar and water in a spray bottle or bowl.
    • Lightly apply to the affected area (do not drench the mattress).
    • Blot with a clean, dry cloth.

  4. Apply baking soda
    Once the surface is only slightly damp, sprinkle a generous layer of baking soda over the spot. Baking soda can help absorb remaining moisture and odor.

    • Leave it for several hours, ideally overnight.
    • Vacuum thoroughly with an upholstery attachment.

This method is a practical, home-based approach to How To Get Rid Of Vomit Smell In Mattress when the mess is recent.

What if the vomit smell is old or already set in?

Dry, older stains can be more stubborn, but you can still improve or remove the smell:

  1. Re-moisten the area lightly

    • Lightly mist the area with a vinegar-and-water solution or plain water.
    • The goal is to slightly loosen dried residue, not soak the mattress.

  2. Use a gentle cleaning solution again

    • Repeat the spot-cleaning process with soapy water.
    • Blot, don’t scrub aggressively.

  3. Target deep odor with baking soda

    • Apply a thicker layer of baking soda than you would for a fresh stain.
    • Leave it on at least 8–12 hours.
    • Vacuum thoroughly, going over the area several times.

If the smell is still noticeable, some people repeat this process more than once to reduce the odor gradually.

Is it safe to use strong cleaners on a mattress?

Harsh cleaners can sometimes:

  • Discolor fabrics
  • Leave their own lingering smell
  • Affect certain foam materials

When figuring out How To Get Rid Of Vomit Smell In Mattress, it’s generally safer to start with:

  • Mild soap and water
  • Diluted white vinegar
  • Baking soda

If your mattress has a care tag, check for any cleaning codes or instructions. As a general guideline, avoid soaking the mattress, using bleach directly on fabrics, or applying anything that might break down foam.

How long does it take for the smell to disappear?

The time frame depends on:

  • How much vomit soaked in
  • How quickly you cleaned it
  • Room ventilation and humidity

With prompt cleaning and good airflow, many people notice major improvement within a day or two. Deep or older odors may take several rounds of cleaning and deodorizing to fade significantly.

Can I sleep on the mattress the same night?

You can sleep on it once:

  • The cleaned area is completely dry, and
  • The odor is reduced to a level you’re comfortable with

To speed drying:

  • Use fans or open windows
  • Gently press a dry towel on the area to absorb remaining moisture

Sleeping on a damp mattress can be uncomfortable and may slow down the odor-removal process.

How do I keep the vomit smell from coming back?

To prevent recurring odor:

  • Clean as soon as possible after any accident
  • Ensure the mattress is fully dry before putting sheets back on
  • Use a washable, waterproof mattress protector to keep future spills from soaking in
  • Air out the mattress occasionally by removing bedding and letting it sit in a well-ventilated room
