How To Wash Your Mattress: A Simple, Step‑by‑Step Guide

If you’re wondering how to wash your mattress without damaging it, you’re not alone. Mattresses can’t go in the washing machine, but you can clean, refresh, and care for them safely with a clear process and the right tools. This FAQ walks you through what to do, what to avoid, and how to handle common messes.

What does “washing” a mattress actually mean?

When people search “How To Wash Your Mattress”, they usually mean:

  • Removing surface dirt, dust, and crumbs
  • Treating spills, stains, and odors
  • Freshening the mattress so it feels cleaner and more comfortable

Because mattresses contain foam, fabric, and sometimes springs, they should never be fully soaked or saturated with water. Instead, “washing” your mattress means gentle surface cleaning and spot-treating, using minimal moisture and careful drying.

How To Wash Your Mattress: Step‑by‑Step

1. Prepare the bed

  1. Strip all bedding: sheets, blankets, pillowcases, and any protectors.
  2. Wash bedding according to its care labels.
  3. If you use a mattress protector, clean it as directed before putting it back on.

2. Vacuum the surface

Use the upholstery attachment on a vacuum:

  • Go over the entire top surface slowly.
  • Pay extra attention to seams, tufts, and edges where dust can collect.
  • If possible, vacuum the sides as well.

Why this matters: Regular vacuuming helps remove debris and keeps the surface cleaner before you deal with stains or odors.

3. Spot-clean stains (without soaking)

Stains are usually the biggest concern when asking how to wash your mattress. The key rule: treat small areas with as little liquid as possible.

General approach:

  1. Lightly dampen a clean cloth with cool water and a small amount of gentle, diluted cleaner.
  2. Blot, don’t scrub. Press on the stain, lifting from the outside in.
  3. Use a second cloth, dampened with plain water, to blot away any residue.
  4. Finish with a dry cloth, pressing to remove extra moisture.

Avoid:

  • Pouring cleaner directly on the mattress
  • Using very hot water (which can set some stains)
  • Harsh chemicals that may damage fabrics or foams

Always check the mattress label for any specific care warnings.

4. Deodorize the mattress

For general odors:

  1. Lightly sprinkle baking soda over the dry mattress surface.
  2. Let it sit for at least 30–60 minutes; longer contact time can help with lingering smells.
  3. Vacuum thoroughly to remove the baking soda.

This helps freshen the mattress without adding moisture, which is important for long‑term care.

5. Let it dry completely

After any spot cleaning:

  • Allow the mattress to air dry fully before putting bedding back on.
  • Open windows or use a fan to improve airflow.
  • If one area is damp, focus airflow there.

A mattress that isn’t fully dry can feel unpleasant and may not wear as well over time.

How often should you clean or “wash” your mattress?

How often you follow a full how to wash your mattress routine depends on use and personal preference, but many sleepers find this helpful:

  • Light refresh (vacuum and deodorize): every 1–3 months
  • Spot cleaning: as soon as a spill or stain occurs
  • Deeper surface clean: 1–2 times per year, or when the mattress looks or smells less fresh

Using a removable mattress protector can reduce how often you need deeper mattress cleaning.

Can you clean different mattress types the same way?

Most basic steps are similar, but there are a few considerations:

  • Foam mattresses: Especially sensitive to soaking. Use very minimal liquid and blot gently.
  • Hybrid or innerspring mattresses: Usually have more airflow inside, but still should not be saturated.
  • Pillow‑top designs: Be cautious with seams and tufting; extra layers can hold onto moisture longer.

When in doubt, follow the manufacturer’s care instructions printed on the label or included with the mattress.

What should you avoid when washing your mattress?

To keep your mattress in good condition, avoid:

  • Soaking or steam‑saturating the mattress
  • Bleach or very strong chemicals on fabrics or foams
  • Aggressive scrubbing, which can wear down the surface
  • Closing it up damp with bedding on top, which slows drying

Keeping liquids to a minimum and focusing on blotting, not rubbing, helps protect both comfort and appearance.
