Do You Wash Mattress Protectors? How Often and How to Do It Right

If you’re wondering “Do You Wash Mattress Protectors?”, you’re not alone. Mattress protectors sit quietly under your sheets, catching spills, sweat, and everyday wear—so it’s natural to ask whether they should be washed, how often, and if frequent washing will damage them.

This FAQ-style guide explains if, when, and how to wash mattress protectors, plus simple care tips to help them last longer.

Do You Wash Mattress Protectors at All?

Yes, you should wash mattress protectors regularly.

Even though they don’t touch your skin directly, mattress protectors collect:

  • Body oils and sweat
  • Dust and lint
  • Skin flakes
  • Occasional spills or crumbs

Over time, this build-up can make the protector less comfortable and may reduce its effectiveness. Washing helps keep your sleep surface fresher and maintains the protector’s performance.

How Often Should You Wash a Mattress Protector?

How often you wash depends on how you use your bed, but a common guideline is:

  • Every 1–2 months for general use
  • More often (every 2–3 weeks) if:
    • You sleep hot or sweat heavily
    • You share the bed with pets
    • You frequently eat or drink in bed
  • Immediately after spills or accidents

If you’re unsure, checking your protector monthly and washing when it looks or feels less fresh is a practical approach.

How Do You Wash Mattress Protectors Safely?

Most modern protectors are designed to be washable, but they can be sensitive to heat and harsh cycles, especially if they have a waterproof backing.

General Washing Steps

  1. Read the care label first
    This is the most important step. Follow any specific temperature, cycle, and drying instructions printed on the label.

  2. Use a gentle cycle
    A cold or warm gentle cycle is usually suitable. Hot water can sometimes damage waterproof layers or shrink fabrics.

  3. Choose mild detergent
    Use a liquid, mild detergent. Avoid bleach or strong chemicals unless the care label clearly allows it.

  4. Do not overload the washer
    Give the protector room to move so it washes and rinses evenly.

  5. Zip it up if it has a zipper
    Closing any zippers can help the protector keep its shape and avoid snagging.

Can You Put a Mattress Protector in the Dryer?

In many cases, yes—but with care.

  • Low heat or tumble dry low is typically recommended.
  • High heat can damage waterproof membranes or elastic edging over time.
  • If you want to be extra cautious, air-dry or line-dry the protector until it is completely dry before putting it back on the bed.

Always check the label: if it says “air dry only” or “no tumble dry”, follow that guidance to avoid peeling, cracking, or warping of the backing.

What If the Mattress Protector Is Waterproof?

Waterproof protectors often have a thin protective layer on one side. These need a bit of extra care:

  • Avoid hot water and high-heat drying, which can cause the waterproof layer to break down.
  • Use a gentle cycle and mild detergent.
  • Skip fabric softeners if possible, as they may leave residue on the surface.

For waterproof models, washing too hot or too often can shorten their life. Gentle, regular care is usually best.

Do You Need to Wash a New Mattress Protector Before Using It?

Many people prefer to wash a new mattress protector once before first use.

A pre-wash can:

  • Remove any light manufacturing residues
  • Soften the fabric for better comfort
  • Freshen the overall feel and smell

If the label allows machine washing, a gentle first wash is usually fine.

What If the Protector Has a Stain or Spill?

If something spills, treat it quickly:

  1. Blot, don’t rub
    Gently blot up excess liquid with a clean cloth.

  2. Pre-treat the spot
    If allowed by the care label, apply a small amount of mild detergent or stain remover to the area before washing.

  3. Wash promptly
    Run a gentle cycle soon after the spill to help prevent long-term staining or odors.

How Long Do Mattress Protectors Typically Last?

Lifespan depends on material quality, how often you wash, and how you dry them.

  • Careful washing on gentle cycles and low-heat drying can help extend their usable life.
  • Signs a protector may need replacing include thinning fabric, peeling waterproof layers, or stretched-out edges that no longer fit snugly.

Do You Wash Mattress Protectors With Other Laundry?

You can usually wash mattress protectors with similar items, such as:

  • Sheets
  • Pillowcases
  • Lightweight blankets

Avoid washing with heavy items like towels or jeans that may create extra friction and wear. Keeping loads balanced and not overfilled helps the protector clean evenly and hold its shape.
