How To Clean a Mattress At Home: Simple Steps and Common Questions

If you’re wondering how to clean a mattress at home without special equipment, you’re not alone. Mattresses collect sweat, dust, spills, and odors over time, and many people aren’t sure where to start. This guide walks through a practical routine you can follow with basic household supplies, plus answers to the most frequent questions about mattress cleaning and stain removal.

Why Bother Cleaning Your Mattress?

A mattress slowly accumulates dust, dead skin, and moisture from everyday use. Over time, this can lead to:

  • Unpleasant odors
  • Visible stains from spills or accidents
  • A surface that simply feels less fresh and inviting

Regularly cleaning a mattress at home helps it feel cleaner, fresher, and more comfortable to sleep on, especially when combined with good bedding care like washing sheets and using a mattress protector.

How To Clean a Mattress At Home: Step-by-Step

1. Strip the bed

Remove all bedding: sheets, pillowcases, mattress protectors, and toppers. Wash them according to their care labels. This gives you full access to the mattress surface.

2. Vacuum the mattress

Use the upholstery attachment on a vacuum to:

  • Go over the entire surface
  • Pay extra attention to seams, edges, and quilting lines

Vacuuming helps remove loose dust and debris before you deal with stains or odors.

3. Spot-clean stains

This is where many people get nervous about how to clean a mattress at home. The key is to:

  • Avoid soaking the mattress
  • Use small amounts of cleaning solution
  • Blot, don’t scrub

Common gentle options include:

  • A small amount of mild dish soap diluted in water
  • A simple paste of baking soda and water for some surface stains

Apply the cleaner lightly to a clean cloth, then dab the stain. Follow by blotting with a separate damp cloth (water only) to lift away residue. Finish with a dry cloth to remove extra moisture.

4. Deodorize with baking soda

Sprinkle a thin, even layer of baking soda over the mattress surface. Let it sit for several hours if possible. Baking soda is widely used to help absorb odors from fabrics and soft furnishings.

Then vacuum thoroughly again to remove the baking soda.

5. Let it air out

If you can, let the mattress air out in a well-ventilated room. Good airflow helps any remaining moisture evaporate before you put your bedding back on.

How Often Should You Clean a Mattress?

There’s no single rule, but many households find this routine helpful:

  • Light refresh (vacuum + airing out): Every 1–3 months
  • Deeper clean (vacuum, spot-clean, baking soda): A few times a year
  • Immediate clean-up: As soon as possible after any spill or accident

The exact frequency depends on how much you use the bed, whether you have pets or small children, and how prone the mattress is to stains and odors.

What About Specific Stains and Spills?

Can I clean fresh spills on a mattress?

Yes, but act quickly:

  1. Gently blot (don’t rub) the spill with an absorbent cloth or paper towel.
  2. Continue blotting until you’ve lifted as much liquid as you can.
  3. Use a small amount of mild cleaner on a cloth to dab the area.
  4. Follow with a damp cloth to remove residue, then a dry cloth.
  5. Allow the area to dry completely.

How do I handle older or set-in stains?

Older stains can be more stubborn. You can:

  • Repeat gentle spot-cleaning several times
  • Allow baking soda to sit longer on the stain before vacuuming

Some stains may never disappear completely, but many can be lightened and freshened with patience and repeated gentle care.

What Should I Avoid When Cleaning a Mattress?

When figuring out how to clean a mattress at home, what you don’t do is just as important as what you do:

  • Don’t soak the mattress – Excess liquid can penetrate deep inside and be slow to dry.
  • Don’t use harsh chemicals that may damage fabric or leave strong residues.
  • Don’t steam clean unless the mattress care instructions specifically say it’s safe.
  • Don’t ignore the care label – Many mattresses include basic cleaning guidance.

How Can I Keep My Mattress Cleaner for Longer?

Prevention helps reduce how often you need deep cleaning:

  • Use a removable, washable mattress protector
  • Wash sheets and bedding regularly
  • Let your mattress air out occasionally by leaving the sheets off for a few hours
  • Address spills and stains as soon as they happen
