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

If you’re searching for How To Wash a Mattress, you’re likely dealing with spills, stains, or just wondering how to keep your bed fresh over time. While you can’t simply throw a mattress into a washing machine, you can clean it thoroughly and safely at home with the right approach.

This guide explains how to wash a mattress step by step, what to avoid, and how to handle common issues like stains and odors.

Can You Actually Wash a Mattress?

You can’t fully wash a mattress with water the way you wash sheets or clothing. Most mattresses are made of foam and layered materials that can be damaged by soaking or heavy moisture.

Instead, when people ask How To Wash a Mattress, they usually mean:

  • How to surface clean it
  • How to remove stains and spills
  • How to deodorize and freshen it
  • How to maintain it so it lasts longer

Think of it as deep spot-cleaning and refreshing, not full immersion washing.

How To Wash a Mattress: Step-by-Step

1. Start by Stripping and Vacuuming

Remove everything from the bed:

  • Sheets, pillowcases, and blankets
  • Mattress protector or pad
  • Any decorative pillows or covers

Wash all bedding according to its care labels.

Then, use a vacuum with an upholstery attachment to clean the entire surface of the mattress, including:

  • Top
  • Sides
  • Seams and edges

This helps remove dust, crumbs, hair, and loose debris before you use any moisture.

2. Treat Spills and Fresh Stains

For fresh liquid spills:

  1. Blot, don’t rub. Use a clean, dry cloth or paper towels to press and soak up as much liquid as possible.
  2. Work from the outside of the stain inward to avoid spreading it.
  3. Avoid scrubbing, which can push liquid deeper into the mattress.

For general stains (non-specific):

  • Mix a small amount of mild liquid detergent with cool water.
  • Dip a clean cloth into the solution, wring it out well, and dab gently on the stain.
  • Follow with a second cloth dampened with plain water to remove soap residue.
  • Blot with a dry towel to remove moisture.

Important: Keep the mattress as dry as possible. Lightly damp, not wet.

3. Deodorize the Mattress Surface

To handle general odor and freshen the surface:

  • Lightly sprinkle baking soda over the entire top of the mattress.
  • Let it sit for at least 30–60 minutes; longer is fine if you can leave it all day.
  • Vacuum the baking soda thoroughly.

Baking soda is commonly used to help absorb odors and moisture from soft surfaces.

4. Spot Cleaning for Common Problems

How do I clean sweat or body stains?

  • Use a mix of mild detergent and water or a small amount of gentle upholstery cleaner designed for fabrics.
  • Apply sparingly with a cloth, blotting rather than soaking.
  • Rinse the area with a damp cloth and blot dry.

How do I clean urine from a mattress?

  • Blot up as much as possible while it is still fresh.
  • Use a lightly damp cloth with mild detergent or a gentle fabric-safe cleaner.
  • Follow with baking soda over the area once it is only slightly damp, let it sit, then vacuum.

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

How do I handle vomit or other biological stains?

  • Wear disposable gloves if desired.
  • Remove any solid material carefully.
  • Blot liquid with paper towels or cloth.
  • Clean with a mild detergent and water solution, then deodorize with baking soda once the area is only slightly damp.

5. Let the Mattress Dry Completely

After cleaning, proper drying is essential:

  • Allow the mattress to air dry in a well-ventilated room.
  • Open windows or use a fan to speed up drying.
  • If possible, stand the mattress on its side to improve airflow.

Do not put bedding back on until the mattress is fully dry to the touch. Trapped moisture can lead to unwanted odors and material damage.

How Often Should You “Wash” a Mattress?

When thinking about How To Wash a Mattress regularly, focus on a routine:

  • Vacuum the surface every 1–3 months.
  • Spot clean stains as soon as you notice them.
  • Deodorize with baking soda a few times a year, or as needed.
  • Use a washable mattress protector to reduce how often deeper cleaning is required.

What Should You Avoid When Washing a Mattress?

To protect your mattress:

  • Do not soak it or pour water directly onto it.
  • Avoid steam cleaners unless the manufacturer says they are safe for your specific type.
  • Skip harsh chemicals like strong bleach or solvents that may damage the materials or cover.
  • Avoid leaving the mattress damp or wet for long periods.

Always check the label or care instructions that came with your mattress. Different materials (like foam, hybrid, or latex) may have specific guidance.
