How To Clean Bed Mattress: Simple Steps for a Fresher Sleep Surface

If you’re searching for “How To Clean Bed Mattress,” you’re usually dealing with spills, stains, odors, or just everyday buildup. This guide walks through what to do step by step, plus answers the most common questions about mattress cleaning and stain removal.

Why Does Cleaning Your Mattress Matter?

Over time, mattresses collect dust, sweat, dead skin cells, and occasional spills. Even if your bed looks clean, it can still hold odors and buildup you can’t see.

Regular cleaning helps:

  • Keep your sleep surface fresher and more comfortable
  • Reduce odors from sweat or accidents
  • Extend the usable life of the mattress materials

You don’t need special tools or harsh chemicals to learn how to clean bed mattress properly—most methods use simple household products.

How To Clean Bed Mattress: Step-by-Step

1. Strip the Bed and Let the Mattress Air Out

  • Remove sheets, blankets, and covers.
  • Wash bedding according to the fabric instructions.
  • If possible, open a window or allow airflow around the mattress for a bit.

Letting your mattress air out helps reduce moisture and light odors.

2. Vacuum the Surface Thoroughly

Use a vacuum with an upholstery attachment to:

  • Go over the entire top surface
  • Pay extra attention to seams, tufts, and edges
  • If safe, vacuum the sides as well

This removes loose dust, crumbs, and debris so you’re not scrubbing them deeper in later.

3. Treat Fresh Spills and Stains Promptly

If a spill just happened:

  • Blot, don’t rub. Use a clean, dry cloth or paper towel to absorb as much liquid as possible.
  • Work from the outside of the spill inward to avoid spreading.
  • Avoid soaking the mattress; too much liquid can penetrate deep and dry slowly.

4. Use a Mild Cleaner for Spot Cleaning

For most stains (like food, drink, or sweat):

  • Mix a small amount of mild liquid soap with cool water.
  • Lightly dampen a cloth with the solution (do not saturate).
  • Gently blot the stain, lifting it from the fabric.
  • Follow with a clean, damp cloth to remove soap residue.
  • Blot dry with a dry towel.

Avoid harsh cleaners or anything that leaves a heavy residue, as these can affect the feel and smell of the mattress.

5. Deodorize With Baking Soda

To freshen and reduce light odors:

  1. Sprinkle a thin, even layer of baking soda over the mattress surface.
  2. Let it sit for at least 15–30 minutes; some people prefer a few hours.
  3. Vacuum the baking soda thoroughly.

Baking soda helps absorb odors and leaves the surface smelling more neutral.

How Do I Clean Specific Types of Stains?

Sweat and General Yellowing

  • Lightly mist or dab with a mix of water and a small amount of mild soap.
  • For lingering odor, follow with baking soda and vacuum after it sits.

Mild Food or Drink Spills

  • Blot immediately, then clean gently with soapy water on a cloth.
  • Avoid hot water, which can set some stains.

Bodily Fluids (Urine, Vomit, Blood)

These can be more stubborn:

  • Blot up as much as possible.
  • Use a gentle cleaning solution and avoid scrubbing aggressively.
  • Allow extra drying time and consider repeating baking soda and vacuuming.

If stains or odors remain strong, many people choose to consult a professional cleaning service.

How Often Should I Clean My Mattress?

You don’t need to deep-clean every week. As a general guideline:

  • Light cleaning (vacuuming + baking soda): every few months
  • Spot cleaning: whenever spills or stains occur
  • Full inspection: when you rotate or flip (if your mattress is designed for that)

Pairing regular mattress cleaning with fresh, washed bedding and a removable mattress protector can make the whole process easier over time.

What Should I Avoid When Cleaning a Mattress?

To keep your mattress in good condition, avoid:

  • Soaking the mattress with water or cleaner
  • Bleach or strong chemicals, unless your mattress care instructions explicitly allow them
  • Steam cleaning if the manufacturer advises against moisture or heat
  • Vigorous scrubbing, which can damage fabric and push stains deeper

Always check any care tag or manufacturer guidelines if you have them.

When Is It Time to Stop Cleaning and Consider Replacement?

Cleaning can help with surface stains and mild odors, but it won’t fix:

  • Deep sagging or loss of support
  • Persistent, strong odors that return after cleaning and airing
  • Visible damage to the internal materials

If your mattress is older and discomfort or structural issues are the main concern, cleaning alone may not restore its feel.
