Can You Wash a Mattress? Safe Cleaning Tips and What to Avoid

If you’re wondering “Can You Wash a Mattress?”, you’re not alone. Spills, sweat, dust, and everyday use can make a mattress feel less than fresh, and many people want to know if they can simply wash it like other bedding. This guide explains what you can and cannot do, plus safe ways to keep your mattress clean and in good condition.

Can You Wash a Mattress with Water?

In most cases, you should not “wash” a mattress in the traditional sense.

Mattresses are not designed to be soaked with water or put in a washing machine. Excess moisture can:

  • Soak deep into the layers
  • Lead to lingering dampness
  • Potentially cause odors or material damage

However, you can clean a mattress safely using dry or lightly damp methods, spot cleaning, and regular maintenance.

What Is the Safest Way to Clean a Mattress?

Instead of asking “Can You Wash a Mattress?” it’s more accurate to ask how to clean it without damaging it.

Basic Mattress Cleaning Steps

  1. Strip the bed
    Remove sheets, pillowcases, and mattress protector, and wash them according to their care labels.

  2. Vacuum the surface
    Use a handheld or upholstery attachment to vacuum the entire mattress surface, including seams and edges. This helps remove dust, crumbs, and loose debris.

  3. Spot clean stains

    • Use a small amount of mild detergent mixed with water.
    • Lightly dampen a clean cloth with the solution (do not soak it).
    • Blot the stain gently, working from the outside in.
    • Follow with a second cloth dampened with plain water to remove residue.
    • Finish by blotting with a dry towel.

  4. Deodorize (optional)
    Lightly sprinkle baking soda over the surface, let it sit for several hours, then vacuum it up. Many people find this helps neutralize mild odors.

  5. Let it air out
    If possible, let the mattress sit uncovered for a few hours in a well-ventilated room so any remaining moisture can evaporate.

Can You Wash a Mattress with a Steam Cleaner?

Some people consider steam cleaning when asking, “Can You Wash a Mattress?”

Steam cleaning may be used cautiously on some mattresses, but there are important points to consider:

  • Check the care instructions on your specific mattress type.
  • Too much steam can overheat or oversaturate materials.
  • Some foams and comfort layers are more sensitive to heat and moisture.

If steam is used, it should be done lightly and evenly, allowing plenty of time for the mattress to dry fully afterward.

Can You Hose Down or Soak a Mattress?

No — soaking a mattress is not recommended.

Using a garden hose, submerging a mattress, or pouring large amounts of water onto it can:

  • Cause the inner layers to retain moisture
  • Make it difficult or nearly impossible to dry completely
  • Potentially lead to odors or material breakdown

If a mattress becomes heavily soaked (for example, from a major spill), gently blotting, careful spot cleaning, and extended drying time in a well-ventilated space are usually the safest approaches.

How Do You Clean Different Types of Mattresses?

While the general rule is the same — do not fully wash or soak — some details differ:

Foam and Hybrid Mattresses

  • Particularly sensitive to excess moisture
  • Best cleaned with light spot cleaning and vacuuming
  • Avoid harsh scrubbing or saturating the foam

Innerspring Mattresses

  • Often have fabric and padding over coils
  • Can be vacuumed and spot cleaned
  • Still should not be soaked or machine washed

In all cases, checking any tags or manufacturer guidance can provide helpful care details.

How Often Should You Clean Your Mattress?

You don’t need to deep clean your mattress constantly, but regular light care helps:

  • Vacuuming every few months
  • Promptly treating spills and stains
  • Airing out the mattress when you change bedding

Using a removable, washable mattress protector can make everyday care much easier and reduce the need for more intensive cleaning.
