How To Get Rid Of Mattress Smell: Practical FAQ Guide

If you’ve just bought a new bed or noticed an odd odor from your current one, you may be searching for How To Get Rid Of Mattress Smell. This guide walks through the most common causes of mattress odors and simple, at-home steps to help reduce or remove them.

Why does my new mattress smell?

Many new mattresses have a noticeable “new mattress smell” when first unboxed. This is often due to:

  • Off-gassing from foams and adhesives releasing trapped manufacturing odors
  • Plastic packaging holding in smells during shipping
  • Storage in warehouses, which can leave a slight chemical or “factory” scent

For most people, this smell is strongest in the first few days and gradually fades as the mattress airs out.

How To Get Rid Of Mattress Smell from a new mattress

Here are simple steps to reduce new mattress odors more quickly:

  1. Air it out in a ventilated room

    • Remove all plastic and packaging right away.
    • Open windows and doors to create airflow.
    • If possible, leave the mattress uncovered (no sheets or protector) for a day or two.

  2. Use fans for better circulation

    • Aim a fan across the surface to help move air over and through the mattress.
    • A ceiling fan can also help disperse lingering smells.

  3. Sprinkle baking soda on the surface

    • Lightly cover the top of the mattress with baking soda.
    • Let it sit for several hours, or preferably overnight.
    • Vacuum thoroughly with a clean upholstery attachment.

  4. Rotate or flip if the design allows

    • Rotating can expose different areas to air and help odors disperse more evenly.
    • Only flip if the mattress is designed to be used on both sides.

How To Get Rid Of Mattress Smell from spills or accidents

Not all smells come from new materials. Some are caused by spills, sweat, or accidents. These may need a slightly different approach.

What’s the first thing I should do after a spill?

Act quickly:

  • Blot, don’t rub: Use clean, dry towels to gently blot up as much liquid as possible.
  • Avoid soaking the mattress: Too much moisture can linger and lead to more odor.

How can I clean and deodorize the area?

A simple, gentle routine can help:

  1. Spot clean with mild soap and water

    • Mix a small amount of mild detergent with water.
    • Lightly dab the stained area with a cloth; avoid oversaturating.
    • Blot with a dry towel to remove excess moisture.

  2. Apply baking soda for odor control

    • Sprinkle baking soda over the damp or previously stained area.
    • Leave it for several hours to absorb smells.
    • Vacuum thoroughly.

  3. Let it dry completely

    • Ensure the mattress is fully dry before covering it with bedding.
    • Use fans and open windows to speed up drying.

Are strong mattress odors a sign something is wrong?

Not always. Mild off-gassing in the first few days is common, especially with foam mattresses. However, consider the following:

  • If the smell is very strong and does not fade after several days of good ventilation, you may want to air it out longer.
  • If the odor is musty or damp, it could indicate moisture buildup or mildew, especially in older mattresses.
  • If you notice visible stains, discoloration, or dampness, focus on cleaning, drying, and deodorizing, and monitor for any changes.

For specific health concerns related to smells or materials, it can be helpful to seek personalized guidance from a relevant professional.

How can I prevent mattress smells in the future?

A few regular habits can help keep odors to a minimum:

  • Use a washable mattress protector to act as a barrier against sweat and spills.
  • Change and wash sheets regularly to reduce buildup of moisture and body oils.
  • Air out the mattress periodically by stripping the bed and opening windows.
  • Vacuum the mattress surface every so often with a clean upholstery tool.
  • Avoid eating or drinking in bed to reduce the risk of spills.

How long does it usually take mattress smells to fade?

For many people, new mattress smells noticeably decrease within a few days of good ventilation and often keep fading over the next week or so. Odors from spills or accidents depend on how quickly the mess was cleaned and how thoroughly the mattress was dried and deodorized.

Using the steps listed under How To Get Rid Of Mattress Smell—especially airing out, baking soda, and regular surface cleaning—can often speed up this process.
