Can You Wash a Pillow Top Mattress Cover? Care, Cleaning, and What to Know

If you’re wondering “Can You Wash a Pillow Top Mattress Cover?” you’re not alone. Many people want to keep their bed fresh and clean but worry about damaging the comfort layers on top of the mattress. This guide answers common questions about washing, spot cleaning, and protecting a pillow top mattress cover.

What Is a Pillow Top Mattress Cover, Exactly?

A pillow top mattress cover usually refers to the soft, padded layer sewn onto the top of a mattress. It’s often permanently attached and filled with foam or fiber for extra cushioning.

It’s important to distinguish this from a removable mattress protector or topper:

  • A pillow top mattress: the plush layer is part of the mattress itself.
  • A removable cover/protector: zips or slips off and is made to be washed.

This difference matters for how you clean it.

Can You Wash a Pillow Top Mattress Cover in the Washing Machine?

In most cases, you cannot machine wash a non-removable pillow top mattress cover. The top layer is usually sewn to the mattress and not designed to go in a washer. Submerging the mattress or saturating the pillow top with water can:

  • Damage the internal foam or padding
  • Lead to clumping or uneven comfort
  • Increase the risk of mold or mildew inside the mattress

If your pillow top has a removable zippered cover, then the answer to “Can You Wash a Pillow Top Mattress Cover?” depends on the care label. Many removable covers are machine-washable on a gentle cycle, but some may require hand washing or spot cleaning instead.

How Do You Safely Clean a Pillow Top Mattress Cover?

If the pillow top is non-removable, focus on surface cleaning, not soaking.

Basic cleaning steps

  1. Vacuum regularly
    Use a handheld or upholstery attachment to gently remove dust, crumbs, and debris from the surface.

  2. Spot clean stains

    • Mix a small amount of mild detergent with cool water.
    • Lightly dampen a clean cloth; do not soak it.
    • Blot (don’t scrub) the stained area.
    • Use a second cloth with plain water to remove detergent residue.
    • Let the mattress air dry completely before making the bed.

  3. Deodorize with care
    Many people lightly sprinkle baking soda over the top, leave it for several hours, then vacuum it up. This can help with general odors without saturating the mattress.

What If the Pillow Top Cover Is Removable?

If your pillow top mattress has a zippered, removable cover, you have more options, but you still need to proceed carefully.

Check before washing

  • Look for a care tag along the seams or zipper.
  • Follow listed instructions for water temperature, cycle type, and drying method.

If the tag says the cover is machine-washable, common guidance includes:

  • Use cold or warm water, not hot.
  • Choose a gentle cycle.
  • Avoid bleach or harsh chemicals.
  • Use a mild detergent.

Drying is just as important:

  • Many covers are best air-dried flat or over a line.
  • If machine drying is allowed, use low heat to reduce shrinkage or damage.

How Often Should You Clean a Pillow Top Mattress Cover?

How often you clean depends on whether the cover is removable and how it’s used.

  • Non-removable pillow top:

    • Vacuum every few weeks or monthly.
    • Spot clean spills and stains as soon as possible.

  • Removable, washable cover:

    • Many people wash it every 1–3 months, or more often if spills, allergies, or pets are a concern.

Using a separate mattress protector over the pillow top can make cleaning easier, since protectors are usually designed for regular machine washing.

Common Mistakes to Avoid

⚠️ Some actions can shorten the life of a pillow top mattress cover:

  • Soaking the mattress with water or cleaner
  • Using strong chemicals like bleach or solvent-based spot removers
  • Scrubbing aggressively, which can damage the fabric and stitching
  • High-heat drying of removable covers when the label advises low heat or air drying
  • Ignoring care tags, which provide the best guidance for that specific material
