How To Remove Mattress Smell: Simple Steps for a Fresher Bed

If you’re searching for “How To Remove Mattress Smell”, you’re likely dealing with a new mattress odor, a musty smell, or lingering scents from spills or sweat. This guide explains why mattresses smell, what’s normal, and how to safely freshen your mattress at home.

Why Does My Mattress Smell in the First Place?

Smells can come from several sources, and understanding the cause helps you choose the right solution.

Common reasons your mattress smells

  • New mattress odor (“off-gassing”)
    Many foam and hybrid mattresses release a temporary smell from manufacturing and packaging. This is often strongest right after unboxing and usually fades with fresh air.

  • Musty or damp smell
    This often happens when moisture reaches the mattress: spills, high humidity, or poor ventilation.

  • Sweat and body odors
    Over time, sweat, skin oils, and natural body odors can build up, especially without a mattress protector.

  • Food, drink, or pet accidents
    These can leave both stains and persistent smells if not cleaned quickly.

How To Remove Mattress Smell: Step-by-Step

Below is a general routine that works for many types of mattress odors. Always check your mattress care tag first and avoid soaking the mattress.

1. Air out the mattress

If you’re wondering how to remove mattress smell from a new bed, ventilation is usually the first and most effective step.

  • Remove all bedding.
  • Open windows to improve airflow.
  • If possible, stand the mattress up on its side to expose more surface area.
  • Let it air out for several hours, or longer if the smell is strong.

Fresh air and time often reduce new mattress and mild musty odors significantly.

2. Use baking soda to absorb odors

Baking soda is a common household choice to neutralize mattress smells.

  1. Lightly sprinkle dry baking soda over the entire surface of the mattress.
  2. Gently rub it in with your hand to help it reach the fabric.
  3. Leave it for at least a few hours; many people prefer to leave it on all day.
  4. Vacuum thoroughly using an upholstery attachment.

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

3. Spot clean any obvious source of odor

If an accident or spill caused the smell, target that area.

  • Blot (don’t rub) fresh spills with a clean, dry cloth.
  • Mix a small amount of mild dish soap with water to create a light, sudsy solution.
  • Dampen (but do not soak) a cloth in the solution and gently dab the spot.
  • Follow with a clean, damp cloth to remove soap residue.
  • Blot dry and let the area air out completely.

Avoid harsh chemicals or heavy saturation, which can damage materials and trap new moisture inside.

How To Remove Mattress Smell from Specific Situations

New foam or hybrid mattress smells

For “factory” or “off-gassing” type smells:

  • Unbox in a well-ventilated room.
  • Remove all plastic wrapping promptly.
  • Let the mattress breathe, uncovered, for a day or more if needed.
  • Use baking soda if the smell lingers.

Musty or damp odors

Musty smells usually signal trapped moisture.

  • Air the mattress in a bright, dry room.
  • Run a fan or use a dehumidifier to speed drying.
  • Use baking soda after it’s dry to absorb remaining odor.

If the mattress has stayed damp for a long time or the musty smell is very strong, many people choose to have it professionally assessed or consider replacement, especially if comfort or cleanliness are affected.

Smells from sweat, pets, or everyday use

For routine body odor or light pet smells:

  • Vacuum the mattress surface regularly to remove dust and debris.
  • Use baking soda deodorizing sessions every few months.
  • Spot clean any fresh accidents right away to prevent lingering odor.

What Should I Avoid When Trying To Remove Mattress Smell?

When deciding how to remove mattress smell, it’s helpful to know what can cause more harm than good:

  • Do not soak the mattress. Excess water can lead to deeper odors or material damage.
  • Avoid strong chemical cleaners unless your care label says they’re safe.
  • Skip heavy fragrances that only mask the smell. Strong perfumes can mix with existing odors instead of removing them.
  • Be cautious with heat. High-heat devices can damage certain mattress materials.

How Can I Prevent Mattress Smells in the Future?

Prevention makes ongoing odor control much easier:

  • Use a removable, washable mattress protector to block sweat and spills.
  • Wash sheets and bedding regularly.
  • Let the mattress air out occasionally by stripping the bed for a few hours.
  • Keep the bedroom reasonably ventilated and dry.
