How to Clean a Mattress (The Complete Guide)

Why Cleaning Your Mattress Matters

Health benefits (reduce allergens, dust mites, bacteria): Mattresses collect dead skin, sweat, dust, and dust-mite waste. Regular cleaning lowers allergen levels and helps reduce triggers for sneezing, congestion, and asthma.

Longevity of your mattress: Dirt and body oils break down foam and fabric over time. Cleaning slows that process and can delay replacement.

Better sleep quality: A fresher sleeping surface supports deeper, less interrupted sleep and can improve how rested you feel.

Quick Table ; Estimated Impact of Regular Mattress Care

Approximate, directional estimates — results vary by mattress type, age, and cleaning method.

Issue / Benefit	Typical Problem	Regular Cleaning Impact	Time to See Results	Prevention Tips
Allergens & Dust Mites	Cause sneezing, congestion, worsen allergies and asthma symptoms	60–90% reduction in allergen load	2–4 weeks	Weekly vacuuming + mattress protector
Bacterial / Odor Build-up	Musty, sweaty smell, light bacterial growth from body oils	70–100% odor reduction, 30–80% bacteria reduction	Immediate to 1 week	Monthly deep cleaning + dehumidifier
Deep Stains	Permanent discoloration from urine, blood, vomit if untreated	Often removes or greatly reduces staining	Immediate treatment crucial	Waterproof protector + immediate spot cleaning
Mattress Lifespan	Sagging, breakdown from accumulated oils and dirt	Extends usable life by 1–3 years	6 months to 2 years	Regular rotation + protective covering
Sleep Quality	Restlessness from allergies, odors, and discomfort	10–25% improvement in sleep quality scores	1–3 weeks	Clean bedding weekly + humidity control

What You’ll Need Before You Start

Vacuum cleaner with upholstery attachment
Mild detergent or enzyme cleaner (for biological stains)
Baking soda
Clean cloths, sponges, or paper towels
Spray bottle (optional)
Fan or well-ventilated space for drying
Mattress protector (optional but recommended)

Step-by-Step: How to Clean Your Mattress

Step 1: Strip and Wash All Bedding

Remove sheets, pillowcases, and toppers. Wash on the hottest setting safe for the fabric to reduce re-contamination.

Step 2: Vacuum the Entire Mattress

Use the upholstery tool and go slowly. Focus on seams and crevices. Vacuum sides, top, and underneath (bed frame area).

Step 3: Spot Clean Mattress Stains

Biological stains (urine, sweat, vomit, blood): Blot fresh liquid immediately. Use an enzyme cleaner per label instructions — enzymes break down proteins and lift biological stains without heavy scrubbing. For blood, use cold water; hot water can set the stain.

Baking soda paste: Mix baking soda with a small amount of water to form a paste for stubborn spots. Apply briefly, then blot and dry. Never soak the mattress. Excess moisture can cause mold and mildew.

Step 4: Deodorize with Baking Soda

Lightly and evenly sprinkle baking soda across the mattress. Leave at least 4 hours; overnight (8–24 hours) is better. Baking soda absorbs odors and moisture, and loosens particles for vacuuming.

Step 5: Vacuum Again for Freshness

Thoroughly vacuum up the baking soda and any loosened debris.

Step 6: Flip or Rotate the Mattress (If Applicable)

Rotate 180° (or flip if the mattress is double-sided) according to the manufacturer’s guidance to even-out wear and avoid sagging.

Special Mattress Cleaning Tips

How to remove deep odors

Lightly mist a solution of equal parts white vinegar and water on the affected area, allow to dry, then sprinkle baking soda and vacuum. Test a small hidden area first and use minimal liquid.

How to deal with liquid spills immediately

Remove bedding and blot the spill with absorbent towels.
Sprinkle baking soda to draw out moisture; leave 30–60 minutes and vacuum.
If biological, follow enzyme cleaner instructions.

When to call professional cleaning

Consider professionals for heavy soiling, set-in stains, persistent odors, suspected mold, or pest infestations. They have extraction tools and sanitizing equipment home methods can’t match.

How Often Should You Clean Your Mattress?

Light cleaning: Vacuum surface monthly.
Deep cleaning: Full clean (vacuum, spot-treat, deodorize) every 6 months.
Spot cleaning: As needed—attend to spills immediately.

Preventive Care: Keep Your Mattress Cleaner for Longer

Use a washable mattress protector to block spills and reduce allergens.
Wash sheets and pillowcases weekly.
Keep indoor humidity around 30–50% to limit mold and dust mites.
Implement a no-eating-in-bed rule and limit pets on the mattress if allergies are a concern.
