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

If you’re searching for “How To Wash a Mattress Pad”, you probably want to clean it properly without shrinking it, damaging the fill, or ruining any special features. This guide walks through when and how to wash different types of mattress pads so you can keep your bed fresh and comfortable.

What Is a Mattress Pad, and Why Does Washing Matter?

A mattress pad is a removable layer that sits on top of your mattress. It may add light cushioning, help protect against stains, or provide a soft surface under your sheets.

Keeping it clean matters because:

It collects sweat, skin oils, dust, and minor spills over time.
A clean pad helps your mattress stay in better condition.
Washing regularly can keep your sleep surface feeling and smelling fresher.

Different pads (quilted, foam, waterproof, fiber-filled, or down alternative) may need slightly different care, which is why “How To Wash a Mattress Pad” is not a one-size-fits-all answer.

How To Wash a Mattress Pad: Step-by-Step Basics

1. Always Start With the Care Label

The care tag is your best guide. It usually tells you:

Machine wash vs. hand wash only
Water temperature (cold, warm, hot)
Dryer recommendations (tumble dry low, no heat, air dry only)
Any “dry clean only” warnings

If the instructions on the tag contradict general advice, follow the label. It is designed for that specific product’s fabric and construction.

2. Pre-Treat Stains Before Washing

Before you wash the whole mattress pad:

Remove it from the bed and shake off loose dust or debris.
Check for visible stains (spills, sweat marks, etc.).
Apply a mild stain remover or gentle detergent diluted with water to stained areas.
Blot with a clean cloth—avoid harsh scrubbing, which can damage fibers or protective coatings.

Machine-Washing a Mattress Pad

Many fabric or quilted mattress pads are machine washable. Here’s a general process.

Recommended Settings

Cycle: Gentle or delicate
Water temperature: Usually cold or warm (check label)
Detergent: Mild, without bleach unless the label says it’s safe

Load it in a front-loading washer or a top-loader without a central agitator when possible. These are usually gentler on bulky items.

Washing Steps

Load the pad loosely so water and detergent can circulate.
Add a small amount of mild detergent; too much can be hard to rinse out.
Select a gentle cycle and recommended temperature.
Add an extra rinse cycle if the pad feels soapy or heavily soiled.

How To Wash a Mattress Pad If It’s Foam or Has Special Features

Not all mattress pads should go in the washing machine.

Foam Mattress Pads

Memory foam or other foam pads are usually not machine washable. Agitation and soaking can cause them to tear or break down.

For foam:

Spot clean only using a mild detergent and water mixture.
Lightly blot the area and avoid soaking the foam.
Let it air dry completely, ideally laid flat, before putting it back on the bed.

Waterproof or Protective Layers

If your mattress pad has a waterproof backing or special barrier, hot water or high heat may crack or warp the layer.

Use cool or warm water, not hot, unless the label allows it.
Choose low heat or air dry in the dryer.
Avoid fabric softeners if the care instructions advise against them, as they may affect absorbency or coatings.

Drying a Mattress Pad Safely

Drying is as important as washing, especially for thicker pads.

Tumble Drying

Many mattress pads can be tumble dried on low heat:

Use low or no heat to help prevent shrinkage and damage.
Add a few clean dryer balls or tennis balls to help fluff quilted pads.
Check periodically so the pad doesn’t overheat or twist into a tight ball.

If the pad comes out slightly damp in thicker areas, you can air dry the rest of the way over a drying rack.

Air Drying

Air drying can be gentler, especially for foam or waterproof-backed pads:

Lay the pad flat to help it keep its shape.
Allow plenty of air circulation around it.
Make sure it is completely dry before putting it back on the mattress to avoid trapped moisture.

How Often Should You Wash a Mattress Pad?

There’s no single rule for how often to wash, but many people find a general pattern helpful:

Every 1–3 months for regular use in typical conditions
More often if there are spills, noticeable odors, or allergies
Immediately after any significant accident or stain

Using a fitted sheet and, optionally, an additional mattress protector over the pad can help extend time between washes.

Common Questions About How To Wash a Mattress Pad

Can I use bleach?

Use only if the care label allows it. Otherwise, bleach can weaken fibers, fade fabrics, or damage special coatings. A gentle detergent is usually sufficient for routine cleaning.

Can I iron a mattress pad?

Most mattress pads are not designed for ironing. Heat from an iron can damage synthetic fibers, melt waterproof layers, or flatten fill.

What if my washer is too small?

If your mattress pad is very thick or oversized:

Do not force it into a small washer; it may not get clean and can strain the machine.
Consider a larger-capacity machine, such as those found in some shared laundry facilities.
For very delicate or bulky pads, professional cleaning may be listed as a recommended option on the label.
