How To Wash Mattress Pad: Simple Steps for a Fresher Bed

If you’re searching for “How To Wash Mattress Pad,” you’re likely wondering whether it can go in the washing machine, what settings to use, and how to avoid damaging it. This guide walks through the basics in a clear, FAQ-style format so you can clean your mattress pad with confidence.

What is a mattress pad, and does the material matter for washing?

A mattress pad is a thin layer that sits on top of your mattress to add light cushioning and protect the surface from everyday wear. Common fill and fabric types include:

  • Cotton or cotton-blend
  • Polyester or microfiber
  • Down or down-alternative
  • Foam or fiberfill
  • Pads with waterproof backing

When deciding how to wash mattress pad properly, the material and care label matter most. Many fabric and fiberfill pads are machine-washable, while some foam pads and specialty designs may require spot cleaning only.

Can I put my mattress pad in the washing machine?

In many cases, yes—but you should always confirm with the care tag first.

General guidelines:

  • Machine-washable pads: Most cotton, polyester, and down-alternative pads
  • Usually not machine-safe: Solid foam pads, pads with complex quilting or delicate attachments, or those clearly labeled “spot clean only”

If the tag allows machine washing, use:

  • A large-capacity washer if possible, so the pad can move freely
  • Gentle or delicate cycle
  • Cold or warm water (avoid hot unless the label specifically allows it)

Step-by-step: How To Wash Mattress Pad safely

Here’s a simple process most fabric and fiberfill pads can follow, assuming the care label allows machine washing.

1. Read the care label

Check for instructions like:

  • Water temperature (cold, warm, or hot)
  • Recommended cycle (gentle, normal)
  • Whether dryer use is allowed
  • Any “do not” warnings (no bleach, no fabric softener, no iron, etc.)

2. Pre-treat stains

If you see spills or spots:

  • Gently blot, don’t scrub, to avoid pushing stains deeper
  • Use a mild stain remover or diluted detergent on the area
  • Let it sit for a few minutes, then move to the wash

3. Load and choose detergent

  • Place the pad in the drum evenly; avoid overloading
  • Use a small amount of mild liquid detergent
  • Avoid heavy-duty detergents, bleach (unless the label allows), or strong additives that can wear down fibers

4. Select the right settings

  • Cycle: Gentle or delicate
  • Spin: Medium to high spin to remove extra water (lower if pad is more delicate)
  • Temperature: Follow the tag; when in doubt, cold is safest

How should I dry a mattress pad?

Drying is just as important as washing for keeping the pad fluffy and intact.

Can I put it in the dryer?

If the label allows machine drying:

  • Use low heat or air dry setting
  • Add a couple of clean tennis balls or dryer balls to help redistribute fill and reduce clumping
  • Pause partway through to shake and fluff the pad, then finish drying

Avoid high heat, which can:

  • Damage synthetic fibers
  • Shrink natural fabrics
  • Weaken waterproof layers or backing

Air-drying tips

If the pad must be air-dried or you prefer it:

  • Lay it flat on a clean surface or drying rack to help it keep its shape
  • Flip and rotate periodically so it dries evenly
  • Allow plenty of time; mattress pads can hold more moisture than regular bedding

Always make sure the pad is completely dry before putting it back on the bed to help prevent trapped moisture and musty odors.

How often should I wash a mattress pad?

How often you wash depends on how frequently it’s used and whether it’s exposed to spills.

As a general guideline:

  • Regular use, no spills: Every 1–3 months
  • If there are spills or accidents: As soon as possible after the incident
  • Guest rooms or rarely used beds: A few times a year, or before and after extended use

Using a fitted sheet over the pad and washing sheets regularly can reduce how often you need to deep clean the pad itself.

What if my mattress pad is waterproof or has a special backing?

Many people searching how to wash mattress pad are especially concerned about waterproof pads.

For these:

  • Check that machine washing and drying are allowed
  • Choose cold or warm water (hot can damage waterproof membranes)
  • Avoid bleach, strong chemicals, and high heat in the dryer
  • Be sure the backing does not stick together during drying—pause and separate layers if needed

If the label says spot clean only, follow those directions instead of machine washing.

How do I spot clean a non-washable mattress pad?

For foam pads or any pad marked “spot clean only”:

  1. Mix a small amount of mild detergent with cool water
  2. Lightly dab the stained area using a clean cloth—do not saturate
  3. Blot with a dry towel to remove excess moisture
  4. Allow the pad to air dry completely, away from direct heat or strong sunlight

Avoid soaking foam or dense pads, as they can be difficult to dry thoroughly.
