How To Steam Clean A Mattress Looking Like A New


Our beds play a significant role in our daily lives, and even with a sheet and protector covering them, a mattress can become a breeding ground for bacteria and allergens, leading to poor sleep quality, allergies, and other health problems. Ensuring your mattress is cleaned regularly to avoid these issues is important.

A steam cleaner can effectively deep-clean and sanitize mattresses without chemicals by killing dust particles, bacteria, and other allergens. This step-by-step guide will show you how to steam clean a mattress!

Steam Clean A Mattress With 7 Easy Steps

Take it as a DIY project; cleaning your mattress with a steam cleaner can deep clean it and remove any dirt and allergens without losing the mattress’s quality. 

  • Steam cleaner preparation:

Choosing an upholstery and fabric steam cleaner is the first step. Ensure you are familiar with the manufacturer’s instructions regarding operation and safety. Once the steam cleaner has been filled with water, let it heat up according to the instructions. 

  • Clean the mattress with a vacuum:

Clean the mattress thoroughly with a vacuum to remove loose dust, debris, and pet hair before steam cleaning. Pay close attention to seams and crevices when vacuuming the mattress surface with an upholstery attachment or handheld vacuum.

  • Make a small test area:

Ensure that the steam cleaner doesn’t damage or discolor the mattress’s fabric by first testing it on a small, inconspicuous area. This way, you can ensure that the steam cleaner is not too hot for the mattress and not causing any discoloration. If everything looks good, you can clean the rest of the mattress.

  • How to steam clean a mattress:

Steam cleaning of the entire mattress can be done once the test area has dried. 

  1. The first step is to work in sections, starting at the top and moving down. 
  2. This will ensure the entire mattress is cleaned and you don’t miss any spots. 
  3. Steam cleaning is effective because it kills bacteria and dust mites, and it also helps to break down any stains that may be on the mattress. 
  4. Use the steam cleaner’s nozzle to apply steam slowly and sweepingly to the mattress surface. It is important not to soak the mattress in water, as excessive moisture can cause mold or mildew to grow.
  • Check for stains and odors:

While steam cleaning, pay particular attention to areas with stubborn stains or odors. For the steam cleaner to penetrate the stained or odorous area, move it closer to the surface and hold the nozzle over it for a few seconds. This will allow the steam to reach a higher temperature, which is necessary to effectively remove the difficult stains and odors. The high temperature also helps to break down the stubborn molecules and break them up into smaller pieces, making them easier to remove.

  • Allow the mattress to dry:

Before replacing any bedding on the mattress after steam cleaning, it’s important to let it dry thoroughly. You can speed up drying by opening windows or turning on fans. Ensure the mattress is completely dry before using it to prevent mold or mildew growth.

  • Protect the mattress:

Use a mattress protector or encasement to keep your freshly steam-cleaned mattress clean. A mattress protector or encasement will create a barrier between the mattress and potential allergens, dust mites, and other contaminants that can accumulate over time. It will also help prolong the life of the mattress by preventing wear and tear.

Things To Remember 

  • Generally, memory foam and latex mattresses should not be cleaned with a steam cleaner, as the high heat and moisture may damage the materials. 
  • Memory foam and latex mattresses are made with delicate materials that can be easily damaged by high heat and moisture. 
  • Steam cleaners generate a lot of heat and moisture, which could damage the materials and cause them to break down or become brittle. 
  • Check your owner’s manual to find out how to clean your mattress.

How To Start Cleaning Preparations? 

There are a few steps you need to follow before you begin steam cleaning a mattress: 

  • Supplies you will need: 

It is important to ensure you have all the necessary items before you begin steam cleaning. A mild detergent or stain remover can help remove difficult stains, while an upholstery steam cleaner can help clean fabrics and upholstery.

  • Follow the manufacturer’s instructions. 

This will help ensure that you use the steam cleaner correctly and safely to not damage the mattress or cause any harm to yourself. Using the right cleaning products and accessories suitable for your steam cleaner is also important.

  • Keep the area well-ventilated: 

Your home should be well-ventilated when you steam clean. For best results, choose a room with opening windows to allow air to circulate and speed up drying. This is because steam cleaning releases a significant amount of moisture into the air that can cause mold and mildew growth if it is not properly ventilated. 

  • Clear the area and remove the bedding: 

Mattress protectors, pillowcases, and sheets should all be stripped from the mattress. This is necessary to remove any allergens, such as dust mites or pet dander, from the mattress and surrounding area. Removing the bedding also helps to inspect the mattress and identify any bed bugs or other pests that may be present.

  • Mattress vacuuming: 

Use a handheld vacuum or vacuum cleaner with an upholstery attachment to thoroughly clean the mattress. Making steam cleaning more effective, this step removes dust, loose debris, and pet hair.

  • Treat the stain first.

Before steam cleaning your mattress, treat any visible stains. Using a mild detergent or stain remover will help you remove the stains. Steam cleaning should be performed after the treated areas have dried completely.

  • Steam cleaner preparation: 

According to your steam cleaner’s instructions, fill the reservoir with water. Ensure the steam cleaner is properly connected and ready for use. If any attachments or nozzles are required, make sure they are securely attached.


Vacuum the mattress thoroughly before you start the steam cleaning process. This will remove any dirt, dust, and debris that could be trapped in the fibers and potentially damage the mattress. Additionally, using the right amount of water and the cleaner solution is important to ensure the mattress is properly cleaned and not damaged.
