How To Get Throw Up Smell Out Of Mattress: Step‑By‑Step FAQ Guide

If you’re searching for “How To Get Throw Up Smell Out Of Mattress,” you probably need a fast, practical solution after an accident. This guide walks you through what to do, what to avoid, and how to keep your mattress fresh without damaging it.

Why Does Throw Up Smell Linger in a Mattress?

Vomit contains liquids, food particles, and stomach acids that can soak deep into mattress layers. If they’re not cleaned quickly and thoroughly:

  • Odors can bind to fabrics and foam
  • Moisture can get trapped below the surface
  • Bacteria growth can make smells stronger over time

Because a mattress is thick and absorbent, surface cleaning alone is rarely enough to remove the smell.

First Steps: What Should I Do Immediately After the Spill?

Acting quickly is the best way to prevent long-lasting odor.

  1. Remove bedding
    Strip sheets, mattress protectors, and blankets and place them in a separate pile to wash.

  2. Gently remove solids
    Use paper towels or a disposable cloth to lift away any solids. Avoid pressing them into the mattress.

  3. Blot, don’t scrub
    Use clean, dry towels to blot up as much liquid as possible. Press firmly, but don’t rub, which can push moisture deeper.

  4. Ventilate the room
    Open windows or use a fan so the area begins to air out while you clean.

How Do I Clean the Stain and Neutralize the Smell?

Here’s a common, mattress-friendly method that focuses on neutralizing odor and removing moisture.

1. Treat the Area With a Mild Cleaning Solution

You can mix a simple solution using items many people already have at home:

  • Cool or lukewarm water
  • A small amount of gentle liquid soap or mild detergent

Lightly dampen (do not soak) a clean cloth with the solution and dab the stained area, starting from the outside and moving inward. This helps lift residue.

2. Use a Vinegar Solution for Odor Control

A diluted vinegar mix can help neutralize lingering smells:

  • Mix equal parts white vinegar and water
  • Lightly spray or dab the affected area
  • Avoid saturating the mattress; aim for a light, even dampness

Let this sit for 10–15 minutes, then blot thoroughly with dry towels.

How Does Baking Soda Help Remove the Smell?

Baking soda is commonly used on mattresses because it can absorb odors and moisture.

  1. Cover the area with a generous layer of baking soda
    Sprinkle it over the cleaned spot and a bit beyond the edges.

  2. Let it sit for several hours
    Many people leave it on for at least 8 hours or overnight so it can work deeply.

  3. Vacuum thoroughly
    Use a vacuum with an upholstery attachment to remove all the baking soda. Go slowly over the area more than once.

If the odor is still noticeable, you can repeat the vinegar and baking soda steps.

Is It Safe to Use Strong Cleaners or Fragrances?

People often wonder if they should use strong chemicals or heavy fragrances to “cover” vomit smells.

  • Harsh chemicals may damage mattress materials or leave their own strong odors.
  • Heavy perfumes or air fresheners usually mask smells temporarily instead of removing them.
  • Always test any cleaner on a small, hidden area first to check for discoloration or damage.

Sticking with mild, water-based solutions and baking soda is usually a mattress-friendly approach.

How Long Will the Smell Take to Go Away?

The time it takes to fully remove the smell can vary based on:

  • How quickly you cleaned the spill
  • How deeply the liquid soaked in
  • The type and thickness of the mattress

Often, a mattress smells much better after one full cleaning cycle and airing out. If you still notice an odor after everything is dry, repeat the process rather than using more liquid at once.

What If the Throw Up Smell Is Still There After Cleaning?

If you’ve followed the basic steps and still catch a sour or musty odor:

  • Repeat the baking soda treatment for a longer period
  • Make sure the mattress is completely dry (a fan or open windows can help)
  • Check if the smell might be coming from pillows, the bed frame, or bedding instead

In some cases, a deeply soaked mattress may hold onto odor in its inner layers. If repeated gentle cleaning doesn’t help, some people choose to focus on prevention going forward: using mattress protectors, washable toppers, or additional layers that are easier to clean.

How Can I Keep My Mattress From Smelling in the Future?

Once you’ve learned How To Get Throw Up Smell Out Of Mattress, it makes sense to prevent future issues where possible.

  • Use a waterproof mattress protector to block liquids from soaking into the core.
  • Wash bedding and protectors soon after any accident.
  • Air out your mattress periodically by removing bedding and opening windows.
  • Address any spills or accidents immediately, before they have time to soak in.
