Can I Wash a Mattress Protector? How to Clean It Safely and Effectively

If you’re wondering “Can I wash a mattress protector?”, you’re not alone. Many people are unsure whether their protector should go in the washing machine, how often it needs cleaning, or if washing will damage waterproof layers or special fabrics. This guide walks through the key questions so you can clean your mattress protector confidently and keep your sleep surface fresh.

What Is a Mattress Protector and Why Does Cleaning Matter?

A mattress protector is a removable layer that fits over your mattress to help shield it from spills, sweat, dust, and everyday wear. Some are fully waterproof, some are quilted, and others focus on adding a light comfort layer.

Regular cleaning matters because it helps:

  • Remove buildup of sweat, skin oils, and dust
  • Keep odors down and the sleep surface feeling fresh
  • Protect your mattress so stains and moisture don’t reach it

A clean protector is usually easier and cheaper to refresh than a stained mattress.

Can I Wash a Mattress Protector in the Washing Machine?

In most cases, yes — you can wash a mattress protector in a washing machine, but the exact method depends on the material and care label.

What should I check before washing?

Always start with the care label attached to the protector. It typically tells you:

  • Whether it’s machine washable or hand-wash only
  • The recommended water temperature (cold, warm, or hot)
  • If it should be tumble dried, line dried, or air dried flat
  • Any do-not-use notes (such as bleach, fabric softener, or ironing)

If you cannot find the label, using a gentle cycle with cold or warm water is usually the safest default.

How Should I Wash a Waterproof Mattress Protector?

Many modern protectors have a waterproof or water-resistant backing, often with a thin protective membrane. To protect this layer:

Basic steps for washing a waterproof protector

  1. Pre-treat spots
    Dab any visible stains with a mild detergent and cool water. Avoid harsh scrubbing that could damage the backing.

  2. Use a gentle cycle
    Choose a delicate or gentle cycle with cold or warm water, not hot, to help preserve the waterproof layer.

  3. Use mild detergent
    A small amount of liquid detergent is usually best.

    • Avoid bleach unless the care label clearly says it’s safe.
    • Avoid fabric softeners, which can leave residue on some materials.

  4. Wash it separately or with light items
    Washing it alone or with lightweight linens can prevent stretching or twisting.

Can I put a waterproof mattress protector in the dryer?

Often you can, but low heat is key:

  • Use low heat or air-dry settings to help prevent the waterproof membrane from cracking or peeling.
  • Remove promptly to reduce wrinkles and avoid overheating.
  • If uncertain, air drying over a clothesline or drying rack is the most cautious option.

How Often Should I Wash a Mattress Protector?

How often you wash depends on how much use and exposure it gets.

As a general guideline:

  • Every 1–2 months for regular use
  • More often (every 2–4 weeks) if:
    • You sleep hot or sweat a lot
    • You share the bed with children or pets
    • There has been a spill or nighttime accident

If there’s a spill, stain, or accident, it’s best to wash the protector as soon as possible to help prevent odors and permanent marks.

What if My Mattress Protector Is Not Machine Washable?

Some specialty or heavily padded protectors may be spot-clean only or recommend hand washing.

For these:

  • Spot clean:
    Use a cloth with mild detergent and cool water. Blot rather than rub.
  • Hand wash:
    Gently move the protector through a tub or basin of water with mild detergent, then rinse thoroughly.
  • Dry completely:
    Lay flat or hang to dry fully before putting it back on the bed.

If the label mentions dry cleaning, follow that instruction to avoid shrinking or damaging materials.

Common Mistakes to Avoid When Washing a Mattress Protector

To keep your protector in good condition, try to avoid:

  • Very hot water: Can shrink fabrics or weaken waterproof layers.
  • High heat drying: May cause cracking or peeling in protective coatings.
  • Strong bleach or harsh chemicals: Can damage fibers and backing.
  • Overloading the washer: Can twist or stretch elastic edges and fitted corners.

Being gentle usually extends the usable life of the protector.

Can I Wash a Mattress Protector With Sheets?

You can, but with some care:

  • Wash it with lightweight items like sheets and pillowcases, not heavy blankets or towels.
  • Avoid overcrowding to let water and detergent move freely.
  • Follow the strictest care instructions among the items in the load (for example, if the protector requires cold water, use cold for everything in that cycle).
