How to Wash Mattress Protector

A mattress protector is a removable bedding item that fits around your mattress or is placed on top of it.

It works to protect your mattress and keep all the fluids, dead skin cells, dust mites and other debris away from your mattress. A mattress protector will hold all threats at bay and get dirty instead of your mattress.

Using a mattress protector can extend the life of your mattress by 5-10 years, depending on the type of the mattress protector you are using and the very quality of your mattress.

Washing Your Mattress Protector

These are the steps for washing a mattress protector:

Remove the Protector from Your Bed

First of all you need to remove your mattress protector from your bed. Use its elastic sides to remove it and start from the corners. However, if you are using an encasement style protector, you have to unzip it and then take it off.

Check for Open Seams

Before you wash your mattress protector, you should check if there are any open seams. If you start washing your mattress protector and the seams are opened, the feathers from it and other stuff, depending on what the protector is made of, can jam your washing machine.

This will also ruin your protector. So, inspect it thoroughly to see if there are any open seams and try to repair them before you do the washing.

Pretreat Stains

To ensure that all the stains will be gone, you can place a gentle detergent directly on the stains and let it sit for some time before you put the protector it in the washing machine.

Let the detergent soak into the stains for at least 15 minutes. This will make the stains come out easier when washing the protector.

Wash Your Mattress Protector

Most mattress protectors usually have a fabric surface and plastic backing and can be washed in a standard washing machine and then tumble dried.

However, you need to do this really carefully as the plastic can easily deform and break apart from the top fabric if you use bleach or a harsh detergent or you set the temperature too high.

How high you should set the temperature will depend on the type of your mattress protector and what’s written on its label. So always check the label before washing the protector.

If there are no labels, it is always safer to wash the protector in a lukewarm or even cold water and with a small amount of gentle detergent.

Rinse the Mattress Protector Twice

To get all the detergent out of your mattress protector, you should rinse it twice. This means that you will need to leave your mattress protector in the washing machine and run it once again when the cycle is complete, but this time without detergent.

Dry Your Mattress Protector

If you want to tumble dry your mattress protector, you should do tumble dry it with your other laundry and on a low heat setting or stop the dryer every 20 minutes and break up its content if you are tumble drying it alone without other laundry that could help with breaking up its content.

If you don’t do this, the content from your mattress protector will be dried in lumps and this will ruin the initial smoothness of your mattress protector.

Remove the protector from the dryer as soon as the cycle is complete to prevent any wrinkling.

How Often to Wash Your Mattress Protector

Since your mattress protector will act as a protective barrier against your mattress and as it will accumulate all the dirt, dead skin cells, bacteria, and other debris and absorb all fluids instead of your mattress, it needs to be washed at least every two months.

But if you are prone to allergies or if you have pets that sleep in your bed with you, then you will need to wash it more often. And, if you accidentally spill something on your mattress protector and you see a stain there, you should wash it immediately to stop the stain from setting.

Can You Dry Clean Your Mattress Protector

You should never dry clean or iron a waterproof mattress protector as this can damage the waterproof membrane of the protector.


Mattress protector is a bedding item that protects your mattress from dirt, dust, dead skin cell, sweat, accidental spills, etc. and significantly prolongs its lifetime.

As a mattress protector serves as a protective barrier, it will quickly become dirty and you need to wash it regularly to keep it smelling fresh and so it can effectively protect your mattress. How exactly you are going to wash your mattress protector will depend on its type.
