How To Clean Foam Mattress Topper? Comprehensive Guide Update 06/2024

To enhance the comfort of a mattress, mattress toppers are a popular and cost-effective option. Mattress toppers are susceptible to spills, body oils, sweat, and other impurities because they sit above the bed, just below the sheets. Using this article, you’ll learn how to clean mattress toppers without harming their internal parts.

Latex and memory foam are two of the most popular materials used in mattress toppers, but feathers and wool are also widespread. When cleaning these materials, care must be taken because they can absorb moisture and cleaning solutions. We’ll show you how to completely and safely clean a memory foam mattress topper and other types of toppers.

How to Clean a Mattress Topper

Depending on how filthy they are, the best method for cleaning mattress toppers may vary. In most cases, baking soda cleaning is all you need to freshen and deodorize. White vinegar or an enzyme cleaner may be necessary if there is a liquid spill.

The delicate foams and other fill materials used in mattress toppers can be damaged or even discolored by aggressive cleaning solvents.

Basic Mattress Topper Cleaning

If you want to clean your mattress topper on a regular basis, follow these steps:

  1. Bedding should be stripped and cleaned in a washing machine.
  2. The topper must be moved with two people, as thinner foam can easily be destroyed when removed from the mattress and placed on the floor or a flat surface.
  3. Use the handheld attachment on your vacuum to completely clean the topping.
  4. Using a small amount of baking soda, cover the top of the topper completely.
  5. Baked-soda-covered topper should sit for at least eight hours.
  6. Remove the baking soda from the topping by vacuuming it well.
  7. Steps 3-6 can be repeated on the other side of the topper if desired.

A vacuum cleaner and baking soda are all that is needed for this procedure, which is fast and easy. Baking soda’s particular ability to neutralize odors and draw moisture out makes it a great deodorizer. The topping should be cleaned and reapplied two to three times per year, or as needed, to keep it looking new. Simply vacuum the topper each time you wash your sheets for an even faster clean.

Your mattress topper may require a more thorough cleaning in some circumstances. Immediately clean up any liquids that have been spilled or are likely to be spilled and use a mild cleaner to remove odors and minimize the risk of lasting stains. Using this method, you may thoroughly clean your mattress topper.

  1. Bedding should be stripped and cleaned in a washing machine.
  2. Using a towel or paper towels, gently soak up any moisture that has accumulated on the topper. To remove excess moisture, gently blot with a paper towel. In order to avoid forcing any moisture further down into the cap, do not rub.
  3. Place the mattress topper on the floor after gently removing it from the mattress.
  4. When in doubt, blot dry and sprinkle baking soda on the mattress before following the instructions in our guide to mattress cleaning.
  5. Shake the ingredients in a spray container until they’re thoroughly combined.
  6. Apply a mist of mattress topper spray to the trouble spots.
  7. Use a cloth to gently wipe up any remaining wetness.
  8. Allow the mattress topper to set for at least eight hours with a thick layer of baking soda on top.
  9. Baking soda can be removed with a vacuum.
  10. Look for stains and/or odors that need to be addressed. Steps 6 through 9 can be repeated as many times as necessary.
  11. Let the topping dry completely before using. This procedure can be sped up by opening the windows, using a fan, or turning up the heat.

It’s possible to clean mattress toppers with a simple solution of water and white vinegar. Vinegar, despite its pungent odor, is an excellent cleaning agent and can help to mask unpleasant odors. The vinegar smell can be reduced by sprinkling some baking soda on the surface after cleaning with the cleanser.

A professional enzyme cleanser may be more effective than a vinegar and water solution for cleaning biological spills and stains. If you go this method, make sure to read the directions on the product packaging and just use a small amount of the cleaner. Mattress toppers can be stained or damaged by cleaning agents in some situations.

A Step-by-Step Guide

Vinegar and baking soda are two of the most common chemicals in cleaning products that are both powerful and easy to use. In addition to the items listed above, you’ll require the following for mattress pad cleanup:

  • A sanitized spray bottle would be ideal.
  • The use of a towel for wiping up any spills (or two for cleaning up a fresh liquid stain).
  • The absence of something.

Remove the mattress pad from the box spring and set it on a flat area before you begin working on your bed makeover.

Step 1: Prepare Your Vinegar Solution

Studying several household cleaning products, experts found that vinegar solutions are most effective the day after they’re produced. Make a fresh vinegar cleaning solution before you begin washing your mattress topper to remove bacteria, germs, and stains.

Your clean spray bottle should be filled with one part white vinegar and one part water. Essential oils can have a profound effect on your sleep quality, so use them sparingly if you want to get a good night’s rest.

Step 2: Soak Up Fresh Liquid Stains with a Towel

In order to avoid spreading the stain further, dab up any remaining liquids with a towel before applying your cleaning solution to a freshly stained mattress topper. Do not attempt to re-use the damp cloth towel afterward; instead, toss it into the washing basket.

Step 3: Spray the Mattress Topper

In order to remove the stain from your mattress pad, spray it with your freshly-made vinegar cleaning solution. Make sure the mattress is dampened completely, but not so much that it’s soaked through.

Cleaning your foam topper may be a good idea if you’ve never done so. Managing a fresh stain outside of your regular cleaning plan merely necessitates attention to the stain itself.

After you’ve soaked the pad fully, use a new towel to remove any remaining water. Keep in mind that the next procedure will take care of any remaining moisture.

Step 4: Sprinkle Baking Soda and Wait

Sprinkle baking soda liberally over your mattress topper (or just the trouble spot) and let it sit for at least eight hours. The baking soda needs time to sit, so start this job early in the day so you can relax on your bed that night..

Step 5: Vacuum, Re-Assemble, and Enjoy!

Use a handheld vacuum cleaner to clean your mattress topper and reassemble your bed after the baking soda has absorbed any remaining liquid and odors. Let the good times roll with a nice night’s sleep and a new foam mattress topper, then!

How to Get Stains Out of a Mattress Topper

If your topper has already been stained, you may need to use a different method of cleaning. Stains can be removed using the following method:

  1. To clean, select a cleaning agent (see below).
  2. To use, dab a clean cloth with a small amount of the solution.
  3. Apply a solution-soaked cloth to the affected area and wipe it gently.
  4. Clean the stain with a cold-water-soaked cloth apart from the discolored area.
  5. Continue until the desired result is achieved.
  6. At least 8 hours after applying baking soda, wait for the baking soda to suck out the moisture.
  7. The mattress should be vacuumed and air-dried to remove any dirt or stains.

Mattress coverings can be cleaned using a variety of products, including vinegar and baking soda.
As a result of the application of commercially available enzyme cleaners, biological stains like blood, sweat and urine can be effectively cleaned. Near the laundry detergent, enzyme cleansers may be purchased in most supermarkets.

Soap and water mix – You can also use a tiny amount of soap and water mix as an alternative. Clean the topper using simply the foam that forms on the surface of the sudsy mixture.

Dilute white vinegar in water 1:1 to remove certain stains as well.

Diluting a mixture of hydrogen peroxide and water may be more effective at removing stubborn stains, such as blood (1:1). If everything else fails, use peroxide cautiously, and only if all other methods have proven ineffective.

Depending on how stubborn the stain is, you may need to try several different cleaning solutions.

When using a cleaner, it is best to use a minimal amount and blot rather than soak. However, if the stain is well ingrained, you may need to use extra cleanser and allow it to soak in for a longer period of time before attempting to remove it. Use plenty of baking soda thereafter and give plenty of time for the mattress topper to dry completely if you choose this way.

Use a mattress protector to keep your mattress clean and stain-free. Waterproof mattress covers are an excellent option for anyone who has pets or small children.

Ways to Extend the Life of Memory Foam Mattress Toppers

Memory foam mattress toppers typically last between three and four years, but with appropriate care, they can last even longer. Because the thinner ones wear out more quickly, their durability depends on the thickness of the material. You may extend the life of your mattress toppers by using fitted sheets and mattress protectors.

Fitted sheets

If you have a mattress topper, certain fitted sheets have deep enough pockets to hold it as well as your mattress. With a 16-inch deep pocket fitted sheet, a 12-inch mattress and a 4-inch height topper may be readily accommodated. If your mattress and topper are different depths, you’ll need a fitted sheet to fit both. Thinner toppers have a firmer feel than thicker ones, which tend to be plusher.

Dust mites and other indoor allergens might build up on your mattress topper if you use fitted sheets. To prevent a buildup of dirt, wash them periodically.

Mattress Protectors

Avoid stains on your mattress by using a mattress protector. It is easy to protect yourself from liquid spills because they are composed of waterproof material. A light detergent and a machine are all that’s needed to clean a mattress protector.
