How Do I Wash a Mattress? A Simple Guide to Cleaning and Care

If you’re asking “How Do i Wash a Mattress”, you’re not alone. Mattresses can’t just be tossed in the washing machine, so it’s natural to wonder how to clean them properly without causing damage. This FAQ-style guide explains what “washing” a mattress really means, how to do it safely, and what to avoid.

Can I Actually Wash a Mattress?

When people search “How Do i Wash a Mattress”, they’re usually asking how to get it fresh, clean, and odor-free.

You generally cannot fully wash a mattress with water like clothing or bedding. Most mattresses are made with foams, fibers, and metals that:

  • Absorb water deeply
  • Take a long time to dry
  • Can develop odors or damage if soaked

Instead of soaking, you clean a mattress using surface cleaning, spot-treating, and deodorizing. The goal is to keep it clean without letting moisture seep too far inside.

What Should I Do Before Cleaning My Mattress?

1. Check the mattress label

Look for any care instructions on the tag. Some mattresses have specific cleaning guidelines, such as:

  • “Spot clean only”
  • “Do not use harsh chemicals”

Following the label helps avoid accidental damage.

2. Strip the bed completely

Remove:

  • Sheets
  • Mattress protector or pad
  • Blankets and pillows

Wash all washable bedding according to its care labels. Clean bedding helps keep your mattress cleaner for longer.

How Do I Wash a Mattress on the Surface?

This is the basic routine for regular mattress cleaning.

Step 1: Vacuum thoroughly

Use a vacuum with an upholstery attachment to remove:

  • Dust
  • Crumbs
  • Loose debris

Pay extra attention to seams and edges, where buildup often collects.

Step 2: Deodorize with baking soda (optional)

Lightly sprinkle dry baking soda over the surface. Let it sit for at least 15–30 minutes, then vacuum it up. Many people use this step to help their mattress smell fresher.

Step 3: Spot-clean stains (not soak)

If you’re wondering “How Do i Wash a Mattress” because of a spill or stain, focus on spot-cleaning:

  1. Blot, don’t scrub
    Use a clean, dry cloth or paper towel to absorb as much liquid as possible.

  2. Use a gentle cleaner
    Common options include a small amount of mild dish soap diluted in water. Apply it sparingly to a cloth rather than pouring it directly on the mattress.

  3. Dab the stain
    Gently dab the area, working from the outside in. Avoid saturating the fabric.

  4. Remove excess moisture
    Blot again with a dry cloth until the area feels only slightly damp.

  5. Let it air dry fully
    Allow the mattress to dry in a well-ventilated room before putting bedding back on.

How Do I Handle Different Types of Stains?

Can I Wash Out Liquid Spills?

For drinks or other liquids:

  • Act quickly to blot up as much as you can
  • Use a small amount of mild soapy water on a cloth
  • Avoid hot water, which can sometimes set stains

What About Odors?

For general odors:

  • Baking soda on the surface, left for a few hours, then vacuumed, is a common approach
  • Good room ventilation can help the mattress air out

Is It Safe to Use Strong Cleaners?

It’s usually best to avoid harsh chemicals, excessive moisture, or steam on a mattress. These can:

  • Break down some fabrics and foams
  • Leave strong smells
  • Introduce more moisture than the mattress can handle

How Often Should I Clean My Mattress?

You don’t need to ask “How Do i Wash a Mattress” every month, but regular, light maintenance goes a long way.

A common routine is:

  • Vacuum every few months
  • Spot-clean stains as soon as they appear
  • Air out the mattress when changing bedding by leaving it uncovered for a short time

Using a mattress protector can make cleaning easier because it takes the brunt of spills and dust.

What Should I Avoid When “Washing” a Mattress?

To keep your mattress in good condition, it’s usually best to avoid:

  • Soaking or saturating it with water
  • Using a carpet cleaner or steam cleaner directly on it
  • Scrubbing aggressively, which can damage the cover
  • Leaving it damp or wet for long periods

The key idea: clean the surface gently and keep the inside as dry as possible.
