How Do You Get Vomit Smell Out Of Mattress? Simple Steps That Actually Help

If you’re searching “How Do You Get Vomit Smell Out Of Mattress”, you’ve likely already cleaned up the mess but are stuck with a lingering odor. This guide walks through why the smell sticks, how to remove it safely, and what to do if it still won’t go away.

Why Does Vomit Smell Linger in a Mattress?

Mattresses are thick, absorbent, and often covered in fabric that holds onto moisture and odors. When vomit soaks in, it can:

  • Penetrate deep into the foam or padding
  • Leave behind proteins, acids, and bacteria that cause strong smells
  • Become harder to treat if it dries before you clean it

That’s why acting quickly and using the right cleaning methods matters.

How Do You Get Vomit Smell Out Of Mattress Step by Step?

1. Remove solids and blot the area

Gently remove any solid material using paper towels or a disposable cloth. Then:

  • Blot, don’t rub – pressing down with clean, dry towels helps pull moisture out
  • Work from the outside of the stain toward the center to avoid spreading it

Avoid forcing liquid deeper into the mattress.

2. Use an enzyme cleaner or mild cleaning solution

For odor from organic stains like vomit, many people find enzyme-based cleaners effective because they help break down odor-causing residues.

If you don’t have one, you can use a mild household solution:

  • Mix a small amount of gentle liquid soap with cool water
  • Lightly dampen (do not soak) a clean cloth
  • Dab the stained area and continue blotting

The goal is to lift residue, not saturate the mattress.

3. Rinse lightly and keep blotting

To reduce soapy buildup that can trap odors:

  • Dampen another cloth with plain cool water
  • Blot the area again to remove remaining cleaner
  • Follow with dry towels to remove as much moisture as possible

Too much water can cause deeper odor and slow drying, so use a light touch.

Can Baking Soda Help Remove the Smell?

Yes, baking soda is commonly used to help neutralize lingering odors.

How to use baking soda on a vomit smell

  1. Once you’ve cleaned and blotted the area, sprinkle a generous layer of dry baking soda over the affected spot.
  2. Gently spread it so it covers a slightly larger area than the stain.
  3. Let it sit for at least several hours – many people leave it on overnight for stubborn smells.
  4. Vacuum the baking soda slowly using an upholstery attachment if possible.

You can repeat this process if the smell improves but doesn’t fully disappear after the first attempt.

What If the Smell Is Still There After Cleaning?

Sometimes, especially if the vomit has soaked deep or sat for a long time, the odor can remain.

Try these next steps:

  • Repeat the enzyme cleaner and baking soda cycle
    Clean, blot, apply enzyme cleaner (following its directions), let dry, then use baking soda again.

  • Air out the mattress thoroughly
    Place it in a well-ventilated room. If possible, open windows or place a fan nearby to increase air circulation.

  • Check the mattress layers
    If your mattress has a removable cover, follow its care label and wash it separately. Make sure it’s fully dry before putting it back on.

If the odor is very strong, very old, or keeps returning, some people choose professional cleaning services that handle mattresses and upholstery.

Is It Safe to Use Vinegar or Strong Cleaners?

Many home remedies mention vinegar, but it has a strong smell of its own and can linger in fabric. Some people use a very diluted vinegar solution to help with odors, but it’s important to:

  • Test a small, hidden area first to check for discoloration
  • Avoid oversaturating the mattress
  • Let it dry completely

Avoid harsh chemicals like bleach directly on most mattress surfaces. These can:

  • Damage fabrics or foams
  • Leave their own persistent odors
  • Potentially discolor or weaken materials

When in doubt, use gentle cleaners, follow the mattress care tag, and avoid anything that could degrade the materials.

How Can I Prevent Vomit Smell From Soaking in Next Time?

While accidents can’t always be avoided, you can make cleanup easier:

  • Use a waterproof mattress protector under your sheets
  • Clean up spills or accidents as soon as you notice them
  • Keep mild cleaner, paper towels, and baking soda accessible for quick action

Protective covers can act as a barrier, so odors and stains are more likely to stay on the surface instead of reaching the mattress core.
