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

If you’re searching for “How To Get Rid Of Vomit Smell On Mattress,” you’re likely dealing with a fresh accident or a lingering odor that just won’t go away. This guide walks you through practical, home-friendly methods to remove both the mess and the smell, and answers common questions about mattress cleaning and odor control.

Why Does Vomit Smell Linger In a Mattress?

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

  • Penetrate the top fabric and foam layers
  • Leave organic residue that bacteria can feed on
  • Trap odors deep inside, especially if not cleaned quickly

Mattresses are absorbent and not easily washable, so acting fast and cleaning thoroughly makes a big difference.

How To Get Rid Of Vomit Smell On Mattress: Step-by-Step

1. Remove solids and excess moisture

  1. Wear gloves if you can.
  2. Gently scoop up any solids with paper towels or a dull utensil.
  3. Blot, don’t rub, the wet area with clean towels to remove as much liquid as possible.

Avoid pushing the vomit deeper into the mattress by scrubbing at this stage.

2. Clean the stain with a gentle solution

A simple cleaning mix can help break down residue:

  • Mix cool water with a small amount of mild liquid soap or a gentle detergent.
  • Lightly dampen a cloth with the solution.
  • Blot the stained area, working from the outside in.

Do not over-soak the mattress. The goal is to lift the residue without saturating the layers.

3. Use baking soda to absorb odor

Baking soda is a common household option for neutralizing smells:

  1. While the mattress is still slightly damp, sprinkle a generous layer of baking soda over the affected area.
  2. Gently press it in with your hand so it reaches into the fabric.
  3. Leave it on for several hours, or if possible, overnight.
  4. Vacuum thoroughly to remove all the powder.

If the odor is strong, this step can be repeated after the mattress dries.

4. Consider a light vinegar solution (optional)

Some people use white vinegar and water as a deodorizing spray:

  • Mix equal parts water and white vinegar in a spray bottle.
  • Lightly mist the stained area (do not soak).
  • Let it sit for 5–10 minutes.
  • Blot again, then re-apply baking soda and vacuum once dry.

Vinegar itself has a temporary smell, but it typically fades as the mattress dries.

5. Let the mattress dry fully

Proper drying helps avoid musty or sour smells:

  • If possible, place the mattress in a well-ventilated room.
  • Open windows, use a fan, or use gentle airflow to help it dry faster.
  • Avoid sleeping on the mattress until it is completely dry.

What If The Vomit Smell Still Won’t Go Away?

Sometimes, even after using the steps above, the mattress may hold onto a faint odor. Here are common follow-up options:

Can I repeat the cleaning process?

Yes. It is common to:

  • Repeat the baking soda treatment
  • Re-clean the spot with a mild soap-and-water solution
  • Re-apply a light vinegar-and-water mist if you used it before

Multiple rounds may be needed if the vomit soaked in deeply or sat for a long time.

When should I consider professional cleaning?

You might look into professional mattress cleaning if:

  • The accident covered a large area
  • The odor is strong and persistent after several home attempts
  • The mattress has other stains or smells you want to address at the same time

Professional equipment can often reach deeper into mattress layers than typical home tools.

Should I throw the mattress away?

Most of the time, that is not necessary, especially for small or moderate spills that are cleaned promptly. However, if your mattress is very old, badly stained, or still smells strongly even after multiple cleanings, some people choose to replace it for comfort and peace of mind.

How Can I Prevent Vomit Smell Problems in the Future?

You can’t prevent every accident, but you can limit damage:

  • Use a water-resistant mattress protector to keep liquid from soaking into the core.
  • Keep absorbent towels, baking soda, and mild cleaner on hand.
  • Try to clean up as soon as possible after an accident.
  • Air out the mattress regularly by stripping bedding and letting it breathe.
