How To Wash a Mattress Protector (with Washer)?

Washing a mattress protector is important to ensure a clean and hygienic sleep surface. Here are the steps to wash a mattress protector using a washing machine:

Remove the Bedding and Read the Label

Before you begin, remove all bedding from the mattress protector and read the label to check for any specific washing instructions. Some mattress protectors may need to be washed in a certain way, such as with a certain temperature of water or detergent.

Inspect and Treat Stains

Take a close look at the mattress protector and treat any stains with a stain remover before washing. 

Select and Add the Detergent

Choose a mild detergent that is suitable for washing a mattress protector. Follow the instructions on the detergent label to determine the correct amount to use.

Select the Water Temperature and Washer Cycle

Set the washing machine to a warm or cold water temperature, depending on the washing instructions for the mattress protector. Select a gentle or delicate cycle to ensure the mattress protector is not damaged during the wash.

Select a Drying Method

Once the wash is complete, it's time to dry the mattress protector. You can either tumble dry it on low heat or hang it up to dry.

Solutions for Specific Stains

Accidents happen, and it's common for a mattress protector to become stained. Here are some solutions for specific stains on a mattress protector:

Urine Stains

Combine one quart of lukewarm water, half a tablespoon of ammonia, and one tablespoon of dish soap. Let it soak for 30 minutes, rinse in cool water, then machine wash.

Blood Stains

Soak the stain in cold saltwater for a few minutes, then blot with a sponge before tossing it into the washing machine.

Coffee or Tea

Oxygen spray or enzyme cleaners are the most effective in removing coffee or tea stains.

How To Wash a Non-Machine Washable Mattress Protector?

If you have a non-machine washable mattress protector, it can be more difficult, but not impossible, to keep clean. Here are some steps to follow to wash a non-machine washable mattress protector properly.

Vacuum the protector: First, use a vacuum cleaner to remove any debris from the surface of the mattress protector. Be sure to pay extra attention to corners and crevices where dirt and dust can accumulate.

Pre-treat stains: If you notice any stains on the mattress protector, use a stain remover or a mixture of water and mild detergent to pre-treat the stain. Rub the solution into the stain and let it work for 10 to 20 minutes before moving on to the next step.

Hand wash the protector: Fill a clean sink or basin with warm water and add a small amount of mild detergent. Put the mattress cover in water and use a soft-bristled brush or sponge to scrub it gently.

Rinse and dry: Once you have finished scrubbing the protector, rinse it thoroughly with clean water to remove all soap residue. Wring out any excess water and hang the protector to dry in a well-ventilated area. Don't let the protector dry in direct sunlight or in a dryer, as this can cause it to shrink or change color.

How Often Should You Wash Your Mattress Protector?

You should wash your mattress protector every month. If you sweat a lot at night or have allergies, you should wash your mattress protector more often to keep allergens and bacteria from building up.

What Is a Mattress Protector?

A mattress protector is a protective cover placed over a mattress to protect it from dirt, stains, and wear and tear. Made of natural or synthetic fibers, there are three main types:

  • Fitted: This fitted sheet type slides over and tucks beneath the mattress.
  • Zippered: The protector fully encases the bed and zips closed.
  • Elastic: Elastic straps hold the protector down to each corner of the bed.

Why Do You Need a Mattress Protector?

There are several reasons why you might need a mattress protector:

  • To protect your investment: A mattress is a significant investment, and a mattress protector can help extend its lifespan by protecting it from spills, stains, and other types of damage.
  • To prevent allergens: A mattress protector can help prevent allergens like dust mites, mold, and pet dander from accumulating in the mattress, which can help reduce the risk of allergies or asthma.
  • To keep the mattress clean: A mattress protector can help keep it clean by protecting it from spills and stains. This can cut down on how often you have to clean the mattress and make it last longer.
  • To protect against bed bugs: A mattress protector provides an additional layer of protection against bed bugs. They can be virtually impossible to eliminate once they infest a mattress.

Things you need to pay attention to:

Clean a Mattress Protector by Hand:

Hand-cleaning a mattress protector is especially helpful for people who are sensitive to chemicals or who like to clean in a more natural way.

Get Your Mattress Protector Ready

Before you start cleaning, make sure to remove any dirt or debris that may be visible on the surface of the protector. You can shake it out or use a vacuum cleaner to remove loose particles.

Use a Wet Cloth with Warm Water and Baking Soda

When your mattress protector is prepared, it's time to start cleaning. Using a wet cloth, gently wipe down the surface of the protector. For added cleaning power, mix a small amount of baking soda with warm water and use this solution to scrub away any stains or dirt.

Make Sure to Air Dry the Mattress Protector 

After you have finished cleaning, it is important to let your mattress protector dry completely before putting it back on the bed. Dry your mattress protector for at least 24 hours. This will prevent any mold or mildew from forming on the surface. 

Wash a Mattress Protector with Machine:

Machine-washing a mattress protector is a great way to keep it clean and fresh. Here are the steps to follow to ensure the best results:

Get the Mattress Protector Ready and Begin Spot Cleaning

Before starting the washing process, removing any dirt or stains from the mattress protector is important. This can be done by spot cleaning with a mild detergent or using a stain remover.

Place Mattress Protector in Your Laundry Bag

To protect the mattress protector during the wash, it's best to put it in a laundry bag. This will help prevent any damage from occurring during the wash.

Wash on a Delicate Cycle with Cold Water

When machine washing a mattress protector, it's best to use a delicate cycle and cold water. This assists to preserve the quality of the fabric and ensure that it stays in good condition for as long as possible.

After the wash is complete, take the mattress protector from the laundry bag and allow it to air dry. This will help prevent any shrinkage or damage to the fabric.

Can a waterproof mattress protector go in the dryer?

Most of the time, it is better to let a waterproof mattress protector air dry than to use a dryer. Dryer heat can damage the waterproof layer, causing it to become less effective.

If you need a dryer, it is best to use the lowest heat setting and remove the protector as soon as it is dry to prevent any potential damage.

When should you wash a mattress protector?

It's best to wash a mattress protector once a month, or more often if it gets dirty or gets wet from an accident or spill.

When should I replace a mattress protector?

Mattress protectors should usually be replaced every one to two years, or sooner if they get damaged or no longer protect your mattress well. When your mattress protector shows signs of peeling or cracking of the waterproof layer, noticeable wear and tear, or if it no longer fits properly on your mattress, then it's time to replace it.
