How To Get Smells Out Of Mattress: Simple, Effective Methods That Work

If you’re searching for “How To Get Smells Out Of Mattress”, you’re likely dealing with a stubborn odor and wondering what actually works without damaging your bed. This guide walks through the most common causes of mattress smells, safe at‑home cleaning methods, and when it might be time to consider replacement instead of repair.

Why Does My Mattress Smell?

Mattress odors usually come from everyday use rather than one single event. Common sources include:

  • Sweat and body oils
  • Spilled drinks and food
  • Pet accidents
  • Mustiness from poor ventilation
  • New mattress “off-gassing” smells

Understanding the cause helps you choose the safest and most effective way to get smells out of a mattress without harsh chemicals or excess moisture.

How To Get Smells Out Of Mattress: Step‑by‑Step

1. Start With Basic Freshening (Good for Mild Odors)

This is a gentle routine that works well for light, general smells.

  1. Strip the bed completely
    Remove sheets, blankets, and mattress protectors and wash them according to their care labels.

  2. Vacuum the mattress surface
    Use a clean upholstery attachment to remove dust, crumbs, and hair. Pay attention to seams and crevices.

  3. Sprinkle baking soda
    Lightly cover the entire surface with dry baking soda. This common household powder is often used to absorb odors rather than just mask them.

  4. Let it sit
    Leave the baking soda on for at least a few hours; many people find a full day helpful for stronger smells.

  5. Vacuum again thoroughly
    Remove all the baking soda so it doesn’t build up in the fabric or foam.

  6. Air it out
    If possible, let the mattress breathe in a well‑ventilated room with windows open. Indirect sunlight can also help with musty odors.

2. How Do I Remove Stronger Odors Like Urine or Sour Smells?

For more noticeable odors, spot-cleaning is usually needed.

Spot-Clean Method (Use Light Moisture Only)

  1. Blot, don’t rub
    If the source is recent, gently blot with an absorbent cloth or paper towel to remove as much liquid as possible.

  2. Use a mild cleaning solution
    Mix a small amount of gentle liquid soap with cool water. Lightly dampen (not soak) a cloth and blot the affected area.

  3. Avoid oversaturating the mattress
    Too much liquid can soak into the core and lead to lingering moisture and new odors, or even material damage.

  4. Apply baking soda on top
    After blotting with the soapy solution, sprinkle baking soda over the area and let it sit for several hours.

  5. Vacuum thoroughly
    Remove all residue and allow the mattress to dry completely before making the bed again.

For very strong pet or bodily odors, repeating this process once or twice may improve results.

3. Is It Safe To Use Vinegar, Sprays, or Strong Cleaners?

Many people looking up How To Get Smells Out Of Mattress wonder about using stronger products. In general:

  • Mild, diluted solutions are usually safer than full‑strength cleaners.
  • Avoid bleach or harsh chemicals, which can discolor fabrics or affect foam materials.
  • Heavy fragrances may mask the smell without fixing the cause and can be irritating for some sleepers.

If you choose to use any cleaner, always:

  • Test a small, hidden area first.
  • Apply with a cloth rather than spraying directly, to control moisture.
  • Allow full drying time before sleeping on the mattress.

4. How Long Does It Take for a New Mattress Smell to Go Away?

“New” or off-gassing odors from foam and textiles are common after unboxing. These smells typically fade as the mattress airs out.

You can help by:

  • Letting the mattress air in a ventilated room for at least a day before use, if possible.
  • Opening windows or running a fan to move air across the surface.
  • Avoiding heavy covers during the first few nights so trapped smells can escape.

These odors usually reduce over days as materials settle.

5. When Should I Worry About Moldy or Musty Smells?

A persistent musty, damp, or earthy odor may mean there has been excess moisture in or around the mattress.

Consider:

  • Has the mattress ever been soaked (flood, spill, or heavy steam cleaning)?
  • Is the bedroom humid or poorly ventilated?
  • Do you see any visible discoloration that looks like growth or staining?

If you suspect deep moisture problems or visible contamination, home cleaning might not fully solve the issue. In these cases, many sleepers choose to replace the mattress for peace of mind and comfort, especially if the odor is strong or getting worse.

6. How Can I Prevent Mattress Odors in the Future?

Regular care can reduce the need to research How To Get Smells Out Of Mattress again:

  • Use a washable mattress protector to catch spills and sweat.
  • Wash bedding regularly to keep surface odors from sinking in.
  • Vacuum and air out the mattress a few times a year.
  • Address spills or accidents right away to limit absorption.
  • Keep the bedroom well ventilated whenever practical.
