How To Get Rid Of Mattress Odor: Practical FAQ Guide

If you’re searching for how to get rid of mattress odor, you’re usually facing one of two things: a new mattress smell, or an older mattress that’s picked up musty, sweaty, or spill-related odors. This guide answers the most common questions and gives step‑by‑step, non‑technical advice to help you freshen your mattress safely.

Why Does My Mattress Smell in the First Place?

Odor sources can be grouped into a few common categories:

  • New mattress smell: Many new mattresses have a temporary “factory” or “chemical” scent from materials and packaging.
  • Body odors: Sweat, skin oils, and normal nighttime perspiration can build up over time.
  • Spills and accidents: Drinks, food, or pet accidents can leave lingering smells if not cleaned thoroughly.
  • Moisture and poor airflow: Humidity, damp rooms, or limited airflow around the bed can lead to musty or stale odors.
  • Dust and everyday use: Dust, dander, and general use can cause a mattress to smell less than fresh.

Understanding the likely source helps you decide how to get rid of mattress odor effectively and safely.

How Do I Get Rid of New Mattress Smell?

New mattress odor is common and usually temporary.

Steps to reduce new mattress smell:

  1. Air it out
    Remove all plastic and packaging. Place the mattress in a well‑ventilated room. If possible, open windows and doors for a few hours at a time.

  2. Use a fan
    A fan aimed across the surface can help move air and speed up the fading of the smell.

  3. Short-term baking soda treatment
    Lightly sprinkle baking soda over the surface, leave it for several hours, then vacuum thoroughly using an upholstery attachment.

  4. Give it time
    Many new mattress odors naturally fade over days to a couple of weeks with regular use and ventilation.

If the odor is unusually strong or gets worse, stop using the mattress and consider contacting the retailer or manufacturer for guidance.

How To Get Rid Of Mattress Odor From Sweat or Everyday Use

For general body odors or a mattress that smells “stale,” the focus is on surface cleaning and deodorizing, without soaking the interior.

Step-by-step routine

  1. Strip the bed completely
    Remove sheets, covers, and any protectors so you can access the full surface.

  2. Vacuum thoroughly
    Use a clean upholstery attachment. Vacuum the top, sides, and (if accessible) the underside to remove dust and debris that can hold odors.

  3. Apply baking soda

    • Sprinkle a light, even layer of baking soda over the entire surface.
    • Gently spread it with a clean hand or cloth; do not rub hard.
    • Leave it for at least a few hours; many people find overnight works well.

  4. Vacuum again
    Slowly vacuum all the baking soda. This helps lift both the powder and embedded odors.

  5. Let it breathe
    If you can, leave the mattress uncovered for a bit with windows open or a fan running.

For many people, repeating this process a few times is an effective answer to how to get rid of mattress odor from regular use.

How Do I Treat Specific Spills or Pet Accidents?

For liquid-related smells, it’s important to act quickly but gently.

General guidelines

  • Blot, don’t rub: Use dry, absorbent cloths or paper towels to blot up as much liquid as possible.
  • Avoid soaking the mattress: Excess moisture can move deeper inside and create new odors or damage.
  • Spot clean only:
    • Use a mild soap-and-water solution on a clean cloth.
    • Dab the affected area, then blot with a dry cloth to remove excess moisture.
    • Repeat as needed, keeping the surface only lightly damp.

For lingering odors after the area is dry:

  • Sprinkle baking soda on the specific spot.
  • Leave it for several hours.
  • Vacuum carefully.

If a severe spill or accident leads to a strong, persistent smell that does not improve with basic cleaning and airing out, some sleepers decide to consult a cleaning professional experienced with mattresses.

Can I Use Vinegar, Essential Oils, or Other Home Remedies?

Many people wonder how to get rid of mattress odor using common household items.

  • Vinegar:
    A very diluted vinegar-and-water solution may help with some odors, but it adds moisture and has its own smell. If you choose to use it, apply sparingly to a cloth (not directly on the mattress), blot gently, and follow with thorough air-drying and baking soda.

  • Essential oils:
    A drop or two mixed into baking soda can add a light scent, but oils can sometimes stain or irritate sensitive skin. Use sparingly and test on a small, hidden area first if possible.

  • Strong chemicals or heavy fragrances:
    These can be harsh on mattress materials and may create new odors rather than solving the original issue. They are generally best avoided on the mattress itself.

When in doubt, gentle cleaning, baking soda, and ventilation are the safest starting points.

How Can I Prevent Mattress Odor in the Future?

A few simple habits can greatly reduce the need to figure out how to get rid of mattress odor later:

  • Use a washable mattress protector to limit sweat and spills reaching the mattress.
  • Wash bedding regularly to keep surface odors under control.
  • Let the mattress air out periodically by stripping the bed and opening windows when possible.
  • Avoid eating and drinking in bed to reduce the chance of spills.
  • Ensure good room ventilation and avoid trapping the mattress against damp walls or floors.
