How To Get Odors Out Of Mattress: Simple Steps That Actually Help

If you’re searching for “How To Get Odors Out Of Mattress,” you’re likely dealing with smells from sweat, spills, pets, or just everyday use. The good news: most common mattress odors can be reduced or removed with simple, gentle methods that are safe for your bed.

Below, you’ll find clear answers to the most frequent questions about mattress smells and how to handle them.

Why does my mattress smell in the first place?

Mattress odors usually come from a few common sources:

  • Sweat and body oils that build up over time
  • Spills from drinks or food
  • Pet accidents or dander
  • Musty smells from poor ventilation or humidity
  • “New mattress” smell from materials releasing odor when first unpacked

Understanding the source helps you choose the right approach to get odors out of your mattress without damaging it.

How To Get Odors Out Of Mattress: What’s the safest general method?

For most everyday odors, a dry, gentle clean is the best starting point.

Step-by-step basic deodorizing

  1. Strip the bed
    Remove sheets, protector, and any mattress pad. Wash these according to their care labels.

  2. Vacuum the mattress surface
    Use the upholstery attachment and go slowly over the top and sides. This helps remove dust, hair, and debris that can hold odor.

  3. Apply baking soda
    Lightly sprinkle baking soda over the entire surface. Focus extra on areas where the odor is strongest.

  4. Let it sit
    Leave the baking soda for at least a few hours; many people prefer to leave it on for most of the day. The longer it sits, the more odor it can absorb.

  5. Vacuum again
    Thoroughly vacuum up all the baking soda. Go over each area more than once.

  6. Air it out
    If possible, open windows or increase airflow in the room. Fresh air can help lingering smells dissipate.

This method is gentle for most mattress types and is a good first choice when figuring out how to get odors out of mattress safely.

What if the odor is from a spill or accident?

When a liquid is involved, it’s important to act quickly but carefully.

Fresh spills (drinks, mild stains)

  • Blot, don’t rub
    Use a clean, dry cloth or paper towels to press down on the area and absorb as much moisture as possible. Avoid scrubbing, which can push liquid deeper.

  • Use a mild cleaning solution
    Lightly dampen a cloth with cool water and a small amount of gentle soap. Blot the area—do not soak it.

  • Dry thoroughly
    Press with a dry towel, then allow the area to air dry completely. A fan can help speed this up.

  • Deodorize after drying
    Once dry, use the baking soda method from above on that area.

Pet accidents or stronger odors

For urine or strong organic odors:

  • Blot up as much as possible.
  • Use a mild, non-bleach cleaner recommended for fabrics, applied sparingly to a cloth, then blot.
  • Avoid saturating the mattress; deep moisture can create new odor problems.
  • Follow with baking soda once the area is mostly dry.

Can I use vinegar or other household cleaners on my mattress?

Many people consider vinegar or stronger cleaners when wondering how to get odors out of mattress. Use caution:

  • Vinegar: Some people use a diluted vinegar solution on fabrics, but it can leave its own smell and may not suit all mattress materials. If used, it should be very diluted, lightly applied via cloth (not sprayed heavily), and followed by thorough drying.
  • Harsh chemicals: Bleach and strong solvents can damage mattress fabrics and materials and may leave lingering fumes. These are generally not recommended.
  • Fragrance sprays: These can mask odors temporarily but may not remove the source.

When in doubt, spot-test a tiny hidden area first, and keep moisture to a minimum.

How long does it take to get mattress odors out?

Odor removal is often gradual:

  • Mild, surface smells: Sometimes improved significantly in a day with baking soda and fresh air.
  • Set-in or deep odors: May take multiple deodorizing sessions over several days or weeks to noticeably fade.
  • Persistent strong odors: If smells remain even after careful cleaning and airing, they may be deeply embedded or related to moisture damage.

Patience and repetition are often key.

How can I prevent mattress odors in the future?

A little regular care can help keep smells from building up.

Simple prevention habits:

  • Use a washable mattress protector
  • Wash sheets and pillowcases regularly
  • Let your mattress air out occasionally (strip the bed for a few hours)
  • Vacuum the surface every so often
  • Address spills and accidents right away

These habits can reduce the need for more intensive odor removal later.
