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

If you’re searching for “How To Clean a Bed Mattress”, you’re likely dealing with stains, smells, spills, or just general buildup from everyday use. This guide walks you through exactly how to clean a mattress safely at home, using common household supplies and gentle methods that work for most mattress types.

What Does It Mean to “Clean” a Bed Mattress?

Cleaning a bed mattress usually involves three main goals:

  • Removing surface dirt and dust
  • Treating stains from sweat, spills, or accidents
  • Reducing odors so the mattress smells fresh again

Most people can handle basic mattress cleaning at home by vacuuming, spot-cleaning, and deodorizing. Deep issues like severe mold, large fluid spills, or structural damage may be better handled by a professional or by replacing the mattress.

How To Clean a Bed Mattress: Step-by-Step

1. Strip the Bed and Check the Care Instructions

Remove all bedding, including mattress protectors and pads. If your mattress has a care tag, read it first. It may tell you:

  • Which cleaning methods are safe
  • Which chemicals to avoid
  • Whether you should keep moisture to a minimum

When in doubt, always choose the gentlest option.

2. Vacuum the Mattress Thoroughly

Use a vacuum with an upholstery attachment to remove dust, crumbs, and hair:

  • Go over the entire surface slowly
  • Pay attention to seams, edges, and tufted areas
  • Vacuum both the top and sides

This simple step can make the rest of the cleaning more effective.

3. Deodorize With Baking Soda

To freshen up odors:

  1. Lightly sprinkle dry baking soda over the entire surface.
  2. Let it sit for at least 30–60 minutes; longer is fine if you have time.
  3. Vacuum up the baking soda completely.

Baking soda helps to absorb smells, especially from sweat and general use.

How Do You Remove Common Mattress Stains?

When learning how to clean a bed mattress, stains are usually the biggest concern. Always spot clean instead of soaking the mattress.

General Rules for Mattress Stain Removal

  • Blot, don’t scrub – scrubbing can push stains deeper.
  • Use a small amount of liquid; too much can lead to dampness inside the mattress.
  • Test any cleaner on a small, hidden spot first.

Sweat and Body Oil Stains

Sweat stains often show up as yellowish patches.

  1. Mix a mild solution of lukewarm water and a small amount of gentle liquid soap.
  2. Lightly dip a clean cloth in the mixture and dab the stain.
  3. Follow with a cloth dampened with plain water to remove residue.
  4. Blot dry with a dry towel.

Food and Drink Spills

If something spills:

  1. Act quickly: blot as much liquid as possible with a clean towel.
  2. Use a mild soap-and-water solution and dab the area.
  3. Blot with a clean, damp cloth, then dry thoroughly.

Urine or Other Strong Odor Stains

For odor-causing stains:

  1. Blot up as much as possible first.
  2. Use a gentle cleaning solution suitable for fabrics, applied with a cloth.
  3. After cleaning, allow extra time for thorough drying, as leftover moisture can worsen smells.

Avoid harsh chemicals unless the care instructions explicitly say they are safe.

How Often Should You Clean Your Mattress?

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

  • Vacuum: about every 1–3 months
  • Spot clean stains: as soon as they appear
  • Deodorize with baking soda: a few times a year or as needed

Using a washable mattress protector can reduce the amount of cleaning your mattress itself will need.

Can You Steam Clean a Mattress?

Steam cleaning is sometimes mentioned in discussions of how to clean a bed mattress, but there are important cautions:

  • Too much moisture or heat can damage certain foams or fabrics.
  • Moisture that seeps deep inside may dry slowly, which can lead to problems over time.

If you’re considering steam, make sure it’s recommended for your specific mattress type and use low moisture with plenty of drying time.

How Do You Dry a Cleaned Mattress Safely?

After any wet cleaning:

  • Blot up as much moisture as possible with dry towels.
  • Let the mattress air dry in a well-ventilated room.
  • If possible, use a fan or open windows to speed up drying.

Do not put bedding back on until the mattress feels completely dry to the touch.
