How To Get Smell Out Of Mattress: Practical Steps That Really Help

If you’re searching for “How To Get Smell Out Of Mattress”, you’re likely dealing with an unpleasant odor that’s making it hard to relax or sleep. This guide walks through common causes of mattress smells and clear, step-by-step ways to remove them safely at home.

Why Does My Mattress Smell in the First Place?

Mattress odors usually come from one or more of these sources:

  • New mattress smells
    Fresh from the factory, some mattresses release a mild “new product” or chemical-like smell as materials air out.

  • Sweat and body odors
    Over time, perspiration, skin oils, and everyday use can create a stale or musty scent.

  • Spills and accidents
    Drinks, food, pet messes, or other liquids can soak in and cause lingering odors if not cleaned quickly.

  • Moisture and poor ventilation
    Humid rooms or a mattress directly on the floor can trap moisture, sometimes leading to musty smells.

Understanding the source helps you choose the best method when deciding how to get smell out of mattress surfaces and deeper layers.

What Is the First Thing I Should Do to Remove Mattress Smells?

Air It Out Thoroughly

Before using any cleaning products, give the mattress as much fresh air as possible:

  1. Remove all bedding, protectors, and pads.
  2. Open windows and doors for airflow.
  3. If possible, stand or prop the mattress so air can circulate around it.
  4. Let it air for several hours or longer.

For new mattress odors, simple ventilation often reduces the smell significantly.

How To Get Smell Out Of Mattress with Common Household Methods

Is Baking Soda Effective for Mattress Odors?

Baking soda is one of the most common home remedies for mattress smells because it helps absorb and neutralize odors rather than just masking them.

How to use baking soda on a mattress:

  1. Vacuum the mattress surface to remove dust and debris.
  2. Lightly sprinkle dry baking soda over the entire surface.
  3. For stronger smells, gently rub the baking soda in with your hand.
  4. Leave it on for at least a few hours; overnight is often more effective.
  5. Vacuum thoroughly again to remove the powder.

This approach is especially helpful for sweat or general mustiness.

Can I Use Vinegar to Get Smells Out?

Vinegar is sometimes used diluted to help with specific odor spots:

  • Mix equal parts white vinegar and water in a spray bottle.
  • Lightly mist (do not soak) the affected area.
  • Blot with a clean, dry cloth.
  • Allow the mattress to dry completely, then use baking soda if desired.

Always test any solution on a small, hidden area of the mattress first to check for discoloration or fabric changes.

What About Pet or Other Strong Odors?

For very strong smells (such as pet accidents or spilled liquids):

  • Act quickly: Blot up as much liquid as possible with paper towels or a cloth.
  • Avoid rubbing, which can push the liquid deeper into the mattress.
  • Use a gentle, mattress-safe cleaner if needed, following its directions.
  • Allow plenty of time for the area to dry completely before covering with bedding.

If odors continue, repeating a baking soda treatment can sometimes reduce them further.

How Do I Get Rid of Musty or Damp Smells?

Musty or “wet” smells can indicate trapped moisture.

Steps to address musty odors:

  • Air the mattress in a dry, well-ventilated space.
  • Use fans to improve airflow across the surface.
  • Apply baking soda and vacuum after several hours.
  • Make sure both the mattress and bed frame are fully dry before putting bedding back on.

If the mattress has been heavily saturated or smells strongly of mold, many people choose to avoid using it further, especially if the odor does not improve with basic care.

How Can I Prevent Mattress Smells from Coming Back?

Once you’ve learned how to get smell out of mattress layers, it’s helpful to prevent future buildup:

  • Use a washable mattress protector to shield against spills and sweat.
  • Wash sheets and bedding regularly.
  • Let your mattress breathe by pulling back bedding during the day occasionally.
  • Keep the area under and around the bed clean and well ventilated.
  • Avoid placing the mattress directly on the floor in humid rooms.

Simple, consistent care can significantly reduce future odors and help your mattress stay fresher longer.

❗ Is It Ever Time to Stop Trying to Deodorize?

Odor removal has its limits. Some people decide to stop trying to freshen a mattress when:

  • Smells remain strong and persistent even after airing out and cleaning.
  • There are visible dark spots or other signs of significant moisture damage.
  • The smell makes the sleeping environment feel uncomfortable despite efforts to improve it.

In those cases, ongoing deodorizing attempts may have only a small effect.

✔️ Quick Mattress Takeaways

Key points consumers should understand about How To Get Smell Out Of Mattress

  • Start simple: Airing out the mattress is often the first and most important step.
