How to Clean a Memory Foam Mattress: A Comprehensive Guide

Memory foam mattresses have become increasingly popular in recent years thanks to their superior support and comfort. However, to keep your investment in tip-top shape, knowing how to clean a memory foam mattress properly is essential. In this blog post, we'll walk you through the process step-by-step, including how to get stains out of a memory foam mattress. With our expert tips, you can maintain the freshness, longevity, and performance of your mattress for years to come.

The Importance of Regular Memory Foam Mattress Cleaning

Why Clean Your Memory Foam Mattress?

Memory foam mattresses are known for their ability to conform to your body's shape, providing excellent support and reducing pressure points. However, over time, sweat, dead skin cells, and allergens can accumulate on the mattress surface, leading to an unhygienic sleep environment. Regular cleaning not only helps maintain the mattress's comfort and support but also prevents the buildup of allergens and bacteria.

How Often Should You Clean Your Memory Foam Mattress?

To keep your memory foam mattress fresh and hygienic, it's recommended to perform a deep clean at least twice a year. In addition, consider spot cleaning or addressing stains as they occur. This way, you can prevent permanent damage to your mattress and prolong its lifespan.

Cleaning a Memory Foam Mattress: Step-by-Step Guide

Gather Your Supplies

Before you start cleaning your memory foam mattress, make sure you have the following items on hand:

  • A vacuum cleaner with a soft brush attachment
  • Baking soda
  • A clean cloth
  • Mild laundry detergent
  • Distilled white vinegar (optional)
  • A spray bottle (optional)

Step 1: Strip Your Bed

Remove all bedding, including sheets, pillowcases, and mattress protectors. Launder these items according to their care labels to ensure a fresh, clean sleep environment.

Step 2: Vacuum the Mattress

Using the soft brush attachment, gently vacuum the entire mattress surface. Pay special attention to seams and crevices, where dirt and allergens tend to accumulate. Vacuuming helps remove dust, dead skin cells, and other debris, maintaining a clean and healthy sleep surface.

Step 3: Deodorize with Baking Soda

Sprinkle a generous amount of baking soda over the mattress, covering the entire surface. Allow the baking soda to sit for at least 30 minutes (or longer for a deeper clean) to absorb odors and moisture. Once the time is up, vacuum the baking soda off the mattress, ensuring no residue remains.

How to Get Stains Out of a Memory Foam Mattress

Address Stains Immediately

The key to removing stains from a memory foam mattress is to tackle them as soon as possible. Blot any excess liquid with a clean, dry cloth before the stain has a chance to set. Avoid rubbing the stain, as this can cause it to spread and penetrate deeper into the mattress.

Cleaning Solutions for Stain Removal

For most stains, a solution of mild laundry detergent and water works well. Mix a small amount of detergent with warm water in a spray bottle, and lightly mist the stain. Using a clean cloth, gently dab the stain until it lifts. Be careful not to oversaturate the mattress, as excessive moisture can damage the memory foam.

Distilled white vinegar can be an effective alternative for tougher stains, such as urine or blood. Mix equal parts vinegar and water in a spray bottle, and apply the solution to the stain. Allow it to sit for a few minutes before gently dabbing the area with a clean cloth. Repeat as necessary until the stain is removed.

Drying Your Memory Foam Mattress

Once you've finished spot cleaning, it's crucial to ensure your memory foam mattress is completely dry. Moisture can lead to mold and mildew growth, which can damage your mattress and pose health risks. Use a clean, dry cloth to blot any excess moisture to speed up the drying process. Additionally, you can use a fan or open a window to increase airflow and promote quicker drying.

Preventing Stains and Maintaining a Clean Memory Foam Mattress

Use a Mattress Protector

Investing in a high-quality mattress protector is one of the best ways to keep your memory foam mattress clean and stain-free. These waterproof, breathable covers help prevent spills, sweat, and allergens from penetrating the mattress, making maintaining a clean sleep environment easier.

Rotate Your Mattress Regularly

To promote even wear and prolong the lifespan of your memory foam mattress, rotate it 180 degrees every three to six months. This practice helps prevent uneven compression and ensures a consistently comfortable sleeping surface.

Maintain a Clean Sleep Environment

In addition to cleaning your memory foam mattress, take steps to maintain a clean sleep environment overall. Wash your sheets and pillowcases weekly, and clean your pillows and mattress protector according to their care labels. Regular cleaning helps minimize allergens and bacteria, promoting a healthier sleep experience.


A clean memory foam mattress not only provides a more comfortable and supportive sleep surface but it also contributes to a healthier sleep environment.

By following our expert cleaning tips and maintaining a regular cleaning schedule, you can extend the life and performance of your memory foam mattress for years to come. So, invest time in cleaning your mattress, and enjoy the benefits of a fresh, hygienic, and comfortable sleep.
