How To Get Mold Out Of Mattress: Practical FAQ Guide

If you’re searching for “How To Get Mold Out Of Mattress”, you’re likely worried about strange spots, a musty smell, or whether your bed is still safe to use. This guide walks through what mold on a mattress is, how to respond, and when it may be better to replace the mattress instead of trying to clean it.

What Does Mold on a Mattress Look and Smell Like?

Mold on a mattress often shows up as:

  • Black, green, or gray spots or patches
  • Clusters of tiny dots that may grow or spread over time
  • Musty, damp, or “earthy” odor that doesn’t go away with airing out

Mold tends to form where moisture is trapped: the underside of the mattress, around the edges, or in areas where spills occurred.

If you notice widespread staining, a strong smell, or soft/damaged areas in the mattress, the mold may be more than just surface-level.

Can You Safely Get Mold Out of a Mattress?

Whether you can get mold out of a mattress depends on:

  • How extensive the mold is
  • How deep it has penetrated
  • The type and age of the mattress

Surface-level spots on an otherwise dry, supportive mattress may sometimes be reduced with careful cleaning and thorough drying.

However, if mold is deep inside the mattress, cleaning the surface will not remove what has already grown in the inner layers. In those cases, trying to save the mattress may not be realistic.

Step-by-Step: How To Get Mold Out Of Mattress (For Light Surface Mold)

If the affected area is small and recent, and the mattress is otherwise in good condition, some people choose to attempt gentle cleaning. Work in a well-ventilated area and consider using basic protective gear like gloves and a mask.

1. Move and Inspect the Mattress

  • Take the mattress to a dry, well-ventilated space if possible.
  • Check all sides, seams, and the underside.
  • If mold covers large areas or the smell is strong and widespread, cleaning may not be enough.

2. Vacuum Carefully

Use a vacuum with a hose attachment to gently remove dust and loose particles from the surface. Empty or clean the vacuum canister right away, preferably outside.

3. Spot Clean the Moldy Areas

You can lightly dampen a clean cloth with a mild cleaning solution such as:

  • Diluted gentle detergent and water
  • A mild mix of water and white vinegar

Blot the stained areas rather than soaking them. The goal is minimal moisture so the mattress can dry thoroughly. Avoid harsh chemicals or saturating the foam or padding.

4. Dry the Mattress Thoroughly

Drying is just as important as cleaning:

  • Place the mattress in direct sunlight if possible, or
  • Use fans and open windows in a dry room

The mattress should become fully dry all the way through before being used again. A mattress that remains even slightly damp can encourage mold to return.

When Should You Not Try to Get Mold Out of a Mattress?

There are situations where replacing the mattress is usually the more practical and protective choice:

  • Mold affects large or multiple areas
  • The mattress has been wet for a long time
  • There is a strong, persistent musty smell
  • The mattress is already sagging, damaged, or very old

In these cases, attempts at cleaning may not remove mold from inner layers, and the problem can recur.

How Do You Prevent Mold from Coming Back?

Prevention is often easier than trying to remove mold once it appears. Some useful habits include:

  • Keep the mattress dry: Clean up spills quickly and allow full drying.
  • Use a breathable mattress protector: This helps shield the mattress from moisture and stains.
  • Allow airflow: Avoid blocking the underside of the mattress and, when possible, air it out.
  • Control room humidity: Mold is more likely in damp environments, such as basements or poorly ventilated rooms.

Rotating or lifting the mattress occasionally can also help you spot early signs of mold before it spreads.

Is It Safe to Sleep on a Mattress After Mold?

If you’ve done your best to get mold out of a mattress but:

  • You can still see visible mold, or
  • There’s a lingering musty smell, or
  • You feel unsure about the cleanliness of the inner layers

then continued use may not be advisable from a cleanliness standpoint. At that point, many people choose to retire the mattress for peace of mind.
