How To Get Sick Smell Out Of Mattress: Simple Steps That Work

If you’re searching for “How To Get Sick Smell Out Of Mattress,” you’re likely dealing with a recent accident or lingering odor from a spill, illness, or bodily fluids. This guide walks you through what to do, what to avoid, and how to keep your mattress fresh without damaging it.

Why Does a Sick Smell Linger in a Mattress?

Mattresses are thick and porous, so liquids and odors can sink below the surface. When that liquid isn’t cleaned up quickly or thoroughly, it can cause:

  • Persistent, sour or musty smells
  • Light staining or discoloration
  • A feeling that the bed never fully “smells clean”

The goal when learning how to get sick smell out of mattress is to remove as much of the source as possible, not just cover it up with fragrance.

First Steps: What Should I Do Right After a Spill or Accident?

1. Strip the bed immediately

Remove sheets, protectors, and mattress pads right away. Wash them following their care labels using a mild detergent and, if suitable, a warm cycle.

2. Blot, don’t rub

Use paper towels or a clean cloth to blot up as much liquid as possible. Press firmly but avoid scrubbing, which can push the fluid deeper into the mattress.

3. Ventilate the room

Open windows or turn on a fan. Good airflow helps reduce odor intensity and speeds drying.

How To Get Sick Smell Out Of Mattress Using Common Household Items

Below is a simple, step-by-step approach using products many people already have at home.

Step 1: Spot-clean the affected area

  1. Mix a gentle cleaning solution:
    • Cool or slightly warm water
    • A small amount of mild liquid detergent or gentle soap
  2. Lightly dampen a clean cloth with the solution.
  3. Blot the stained area, working from the outside in, to avoid spreading.
  4. Follow with a cloth dampened with plain water to remove soapy residue.

Avoid soaking the mattress. Too much water can lead to moldy or musty smells, which are harder to remove.

Step 2: Use baking soda to absorb odor

Baking soda is often used because it helps absorb moisture and neutralize odors:

  1. Sprinkle a generous, even layer of baking soda over the cleaned area.
  2. Gently work it in with your hand or a soft brush.
  3. Leave it for at least several hours, and preferably overnight, for strong smells.
  4. Vacuum it up slowly using a clean upholstery attachment.

You can repeat this step if the smell is still noticeable.

Can I Use Vinegar or Other Cleaners on My Mattress?

Using vinegar

Some people use a diluted white vinegar solution to help with strong odors:

  • Mix one part white vinegar with two parts water.
  • Lightly mist the area (do not oversaturate).
  • Blot with a dry cloth.
  • Follow with baking soda to help remove both moisture and smell.

However, always check your mattress care instructions first. Some materials, such as certain foams, may not respond well to acidic solutions or heavy moisture.

What to be careful with

Avoid:

  • Bleach or harsh chemicals, which can damage fabrics and foam
  • Strong, oil-based cleaners that may leave residue
  • Heavy fragrances used only to mask odor instead of removing it

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

This depends on:

  • How deep the liquid penetrated
  • How quickly you treated the area
  • Room airflow, humidity, and temperature

In many cases, a mattress that’s been cleaned and treated with baking soda can smell significantly better within a day or two. Stronger odors may require repeating the cleaning process or giving the mattress more time to air out.

When Should I Be Concerned About the Odor?

While this guide focuses on mattress care, not health, it’s reasonable to pay attention if:

  • The smell gets worse over time
  • You notice visible mold or heavy discoloration
  • The mattress still feels damp after several days

These can be signs that the odor source is deep inside the mattress, or that it has taken on moisture that’s difficult to remove.

How Can I Prevent Sick Smells in My Mattress in the Future?

A few simple habits can help:

  • Use a waterproof mattress protector to keep liquids from soaking in.
  • Clean spills right away instead of waiting.
  • Air out your mattress occasionally by removing bedding and opening windows.
  • Vacuum the mattress surface now and then to remove dust and debris.

These steps don’t guarantee that accidents won’t happen, but they make cleanup faster and odors less likely to linger.

✔️ Quick Mattress Takeaways

Key points to remember about how to get sick smell out of mattress:

  • Act fast: Strip bedding, blot up liquids, and ventilate the room as soon as possible.
  • Clean gently: Use a mild soap-and-water solution, and avoid soaking the mattress.
  • Deodorize with baking soda: Let it sit for hours or overnight, then vacuum thoroughly.
  • Consider light vinegar use: Only if compatible with your mattress materials and used sparingly.
  • Repeat if needed: Strong odors may need more than one cleaning and deodorizing cycle.

With a calm, step-by-step approach, most sick smells can be greatly reduced or removed while keeping your mattress in good condition.
