How To Get Vomit Smell Out Of Mattress: Simple Steps That Actually Help

If you’re searching for “How To Get Vomit Smell Out Of Mattress,” you’re likely dealing with a fresh accident—or stubborn odor that just won’t go away. This guide walks you through what to do, what to avoid, and how to keep your mattress fresh without damaging it.

Why Does Vomit Smell Linger in a Mattress?

Vomit contains moisture, food particles, and strong-smelling acids. When it soaks into a mattress, it can:

  • Penetrate deep into the foam or padding
  • Leave organic residue that bacteria feed on
  • Cause long-lasting odors if not cleaned properly

Because mattresses are thick and absorbent, surface cleaning alone often isn’t enough. Effective odor removal means dealing with both the stain and the smell trapped inside.

First Steps: What To Do Immediately After a Spill

Q: What should I do right away when vomit gets on my mattress?

Acting quickly is one of the most important parts of How To Get Vomit Smell Out Of Mattress. Here’s a simple order to follow:

  1. Remove bedding
    Strip sheets, mattress protectors, and blankets and set them aside for separate washing.

  2. Blot, don’t rub
    Use paper towels or a clean cloth to gently blot up as much liquid as possible.

    • Rubbing can push the vomit deeper into the mattress.

  3. Prepare a mild cleaning solution
    Many people use a mix of cool water and a small amount of gentle dish soap.

    • Avoid harsh cleaners that could damage fabric or foam.

  4. Spot clean the affected area
    Lightly dab the area with the solution using a clean cloth, then blot with a dry cloth to remove excess moisture.

The goal at this stage is to remove residue before it sets, without soaking your mattress.

Deep Cleaning: How To Get Vomit Smell Out Of Mattress

Q: I cleaned the stain, but the odor is still there. What now?

Once visible mess is gone, it’s time to tackle lingering odors. A common, mattress-friendly method uses baking soda.

Step-by-step odor removal

  1. Lightly mist with a water–vinegar mix (optional)

    • Some people use a 1:1 mix of water and white vinegar in a spray bottle.
    • Light mist only—do not soak.
    • Blot excess moisture after a few minutes.

  2. Apply baking soda generously
    Sprinkle a thick, even layer of baking soda over the affected area. This helps absorb both moisture and odor.

  3. Let it sit for several hours
    Ideally, leave the baking soda on for at least 8–10 hours, or overnight.

    • The longer it sits, the more odor it can help absorb.

  4. Vacuum thoroughly
    Use a vacuum with an upholstery attachment to remove all the baking soda from the mattress surface and seams.

  5. Repeat if needed
    Stubborn smells sometimes require a second round of baking soda treatment.

Is It Safe to Use Strong Cleaners on a Mattress?

Q: Can I use bleach or heavy-duty cleaners to remove the smell?

For most mattresses, strong chemicals are not recommended. They can:

  • Break down foams and fabrics
  • Leave their own strong, unpleasant odors
  • Cause discoloration or rough textures on the surface

Instead, focus on gentle cleaning methods like mild soap, diluted vinegar, and baking soda. If your mattress has a care label, follow any specific cleaning instructions included there.

How Long Does It Take for the Smell to Go Away?

Q: Will the vomit smell disappear right away?

Odor removal can take time, especially if vomit has soaked deeply into the mattress. In general:

  • Fresh spills: Often improve significantly after one full cleaning and baking soda treatment.
  • Older or set-in spills: May need multiple treatments over several days.

A key part of How To Get Vomit Smell Out Of Mattress is proper drying. A damp mattress can trap smells, so after cleaning:

  • Allow plenty of airflow (open windows, turn on a fan).
  • Avoid putting on sheets until the mattress is completely dry to the touch.

What If the Smell Still Won’t Go Away?

Q: I’ve tried cleaning and baking soda, but I can still smell it. What next?

If the odor persists:

  • Repeat the cleaning process, focusing on a smaller, targeted area.
  • Try longer baking soda soaks, such as leaving it on for a full day.
  • Consider placing the mattress in a well-ventilated space for an extended period to air out.

In some cases where the spill was heavy or left for a long time, the smell may be deeply embedded. At that point, many people weigh whether continued cleaning is worth it based on age and condition of the mattress.

How To Prevent Future Smells From Setting In

Q: How can I protect my mattress from vomit and other spills in the future?

Simple prevention can make any future cleanup much easier:

  • Use a water-resistant mattress protector to create a barrier.
  • Wash bedding promptly after any accident.
  • Keep absorbent cloths and gentle cleaner nearby if you’re caring for children, pets, or anyone prone to spills.
