How To Clean Mattress Cover: Simple Steps for a Fresher Bed

If you’re searching for “How To Clean Mattress Cover”, you’re likely wondering whether it can go in the washer, what products are safe, and how to deal with spills or stains without damaging your mattress. This guide walks through practical, easy-to-follow steps so you can clean your mattress cover with confidence.

What Is a Mattress Cover and Why Does Cleaning It Matter?

A mattress cover (often called a protector, encasement, or zippered cover) is a removable layer that goes over your mattress. It helps shield the mattress from sweat, spills, skin oils, dust, and everyday wear.

Keeping it clean matters because:

  • Build-up of sweat and oils can lead to odors and discoloration.
  • Spills or accidents can soak through if not handled quickly.
  • Dust and debris collect over time, especially in seams and zippers.

Regularly learning how to clean mattress cover helps keep your sleep surface feeling fresher and extends the life of both the cover and the mattress underneath.

Can I Wash My Mattress Cover in the Washing Machine?

In many cases, yes—but it depends on the fabric and construction.

Always start by checking the care label. It should tell you:

  • Whether the cover is machine washable or spot-clean only
  • The recommended water temperature (cold, warm, or hot)
  • Drying instructions (tumble dry low, line dry, no heat, etc.)

If there is a waterproof membrane, high heat can sometimes damage or warp that layer, so following the label is important.

Step-by-Step: How To Clean Mattress Cover Safely

1. Remove and Pre-Treat Stains

Unzip and remove the cover carefully, especially if it’s snug around corners.

For visible stains:

  1. Blot, don’t rub: If the stain is fresh, gently blot with a clean cloth to remove excess liquid.
  2. Use a mild cleaner: Apply a small amount of gentle detergent mixed with water to the stain.
  3. Dab gently: Work from the outside of the stain toward the center.

Avoid harsh chemicals or bleach unless the care label specifically allows them, as they can weaken certain fabrics.

2. Machine Wash (If Allowed)

If the label says it’s machine washable:

  • Water temperature: Use the recommended setting—often cold or warm.
  • Detergent: Choose a mild, liquid detergent and avoid fabric softeners if the cover is waterproof.
  • Cycle type: A gentle or normal cycle is usually sufficient.
  • Load size: Wash the cover on its own or with similarly lightweight items to reduce stress on seams and zippers.

3. Hand Wash for Delicate or Non-Machine Covers

If the label suggests hand washing:

  1. Fill a bathtub or large basin with lukewarm water.
  2. Add a small amount of mild detergent.
  3. Submerge the cover and gently agitate.
  4. Rinse thoroughly until the water runs clear.
  5. Gently press out excess water without wringing.

How Should I Dry a Mattress Cover?

Drying is where many covers can be accidentally damaged, especially those with waterproof layers.

Common recommendations include:

  • Air dry or line dry: Often the safest option to prevent shrinkage and protect membranes.
  • Tumble dry low: If allowed, use low heat and remove promptly to avoid overheating.
  • Avoid high heat: High temperatures can cause waterproof backing to crack, peel, or warp.

Make sure the cover is completely dry before putting it back on the mattress to avoid trapped moisture.

How Often Should I Clean a Mattress Cover?

Frequency depends on use and environment, but many people find this schedule helpful:

  • Every 1–3 months for general maintenance
  • Immediately after spills or accidents
  • More often if you sweat heavily, allow pets on the bed, or don’t use a top sheet

Regular washing keeps build-up to a minimum, making each cleaning easier.

How To Clean Mattress Cover With Specific Issues

What if the Cover Has a Strong Odor?

  • Wash following the care label.
  • 📝 Optional tip: A second rinse cycle can help remove lingering detergent and smells.
  • Air drying in a well-ventilated space can also help odors dissipate.

What If My Mattress Cover Says “Spot Clean Only”?

For non-removable or “spot clean only” covers:

  1. Mix a small amount of detergent with water.
  2. Lightly dampen a cloth with the solution.
  3. Blot the stained area without soaking the fabric.
  4. Wipe with a separate cloth dampened with clean water.
  5. Allow to air dry completely before making the bed.

Avoid saturating the material so moisture doesn’t reach the mattress core.

Common Mistakes to Avoid When Cleaning a Mattress Cover

  • Skipping the care label and guessing at wash/dry settings
  • Using bleach or harsh chemicals that can weaken fabric or damage coatings
  • High-heat drying that may shrink the cover or harm waterproof layers
  • Putting it back on damp, which can trap moisture against the mattress

Being gentle and following recommended instructions usually leads to better long-term results.
