How To Wash The Mattress: Simple Steps for a Cleaner Bed

If you’re searching for “How To Wash The Mattress,” you’re likely wondering how to clean it deeply without damaging the materials. While you can’t usually put a mattress in a washing machine or soak it in water, you can safely freshen, spot-clean, and sanitize it at home with the right method.

This guide explains how to wash the mattress surface, what to avoid, and how to handle stains and odors.

Can You Actually “Wash” a Mattress?

Most mattresses are not designed to be fully washed with water. Excess moisture can:

  • Damage foams or fillings
  • Encourage mold or mildew inside the mattress
  • Shorten the mattress’s usable life

When people ask How To Wash The Mattress, they usually mean:

  • How to clean the surface fabric
  • How to remove stains, spills, and odors
  • How to freshen the mattress periodically

So the goal is controlled, surface-level cleaning rather than soaking.

How To Wash The Mattress: Step-by-Step Surface Cleaning

1. Prepare the mattress

  1. Strip all bedding, including protectors and pads.
  2. Check the mattress label for care instructions. Some specify which cleaners are safe.
  3. Open windows if possible to help with drying.

2. Vacuum thoroughly

Use a vacuum with an upholstery attachment to gently clean:

  • The entire top surface
  • Seams and crevices
  • Sides of the mattress

This removes dust, crumbs, pet hair, and loose debris before you introduce any moisture.

3. Spot-clean stains (not soak)

For most fresh stains:

  1. Blot, don’t rub with a dry cloth or paper towel to absorb as much as possible.
  2. Mix a small amount of mild liquid detergent with cool water.
  3. Dampen (do not soak) a clean cloth with the solution.
  4. Gently blot the stained area, working from the outside in.
  5. Use a second cloth dampened with plain water to blot away detergent residue.
  6. Finish with a dry cloth to remove excess moisture.

For older or stubborn stains, you can repeat the process, always keeping the mattress as dry as possible.

How To Handle Specific Mattress Stains

Sweat and general discoloration

  • Lightly spray or dab a mix of water and mild detergent or a gentle upholstery cleaner.
  • Blot with a dry cloth and let air-dry completely.

Food and drink spills

  • Blot immediately to remove liquid.
  • Use mild detergent and water as above.
  • Avoid hot water, which can set some stains.

Urine or other strong odors

  • Blot thoroughly first.
  • A solution of water and a small amount of gentle detergent can help with initial cleaning.
  • After cleaning, sprinkle baking soda over the area, leave for several hours, then vacuum to help with lingering odors.

If odors remain after several attempts, many people choose to use a mattress protector going forward to prevent new penetration.

How To Deodorize and Freshen the Mattress

Even without visible stains, a mattress can hold everyday odors.

  1. After vacuuming, sprinkle a light, even layer of baking soda across the surface.
  2. Leave it for several hours or, ideally, most of the day.
  3. Vacuum thoroughly to remove the baking soda.

This simple step is often enough to make the mattress feel fresher.

How Often Should You “Wash” or Deep-Clean a Mattress?

You don’t need to deep-clean frequently. Many sleepers find this schedule manageable:

  • Light refresh (vacuum + baking soda): every 3–6 months
  • Spot-clean stains: as soon as they appear
  • Check for odors or dampness: especially after spills or humid weather

Using a removable, washable mattress protector reduces how often you’ll need to wash the mattress surface.

What Should You Avoid When Cleaning a Mattress?

When learning How To Wash The Mattress, knowing what not to do is just as important:

  • Do not soak the mattress or pour water directly on it.
  • Avoid harsh chemicals like strong solvents or bleach, which can damage fabrics and foams.
  • Don’t use a steam cleaner unless the mattress care label clearly allows it; steam can force moisture deep inside.
  • Don’t put mattresses in direct intense heat (like hairdryers on high or heaters very close) to dry them. Gentle air-drying is safer.

If a large spill has soaked deeply into the mattress and it stays wet for a long time, the damage may be difficult to fully reverse at home.

How Do You Dry a Mattress After Cleaning?

Drying well is a key part of How To Wash The Mattress safely.

  • Press with dry towels to absorb as much moisture as possible.
  • Let the mattress air-dry completely before putting bedding back on.
  • Improve airflow with a fan, open windows, or, if possible, move the mattress to a drier room.
  • If one area was cleaned heavily, you can lean the mattress against a wall so air reaches both sides.

The mattress should feel completely dry to the touch, without cool or damp spots.
