How to deep clean a mattress?


Deep cleaning a mattress is an essential task that often gets overlooked. Over time, mattresses accumulate dust, dirt, allergens, and even stains. Regularly deep cleaning your mattress not only helps maintain its longevity but also promotes a healthier sleep environment. In this article, we will explore the steps and techniques involved in deep cleaning a mattress, ensuring a fresh and hygienic sleeping surface.

Step 1: Vacuuming

Materials used: Vacuum cleaner with upholstery attachment.

The first step in deep cleaning a mattress is to thoroughly vacuum it. Start by removing all bedding and pillows from the mattress. Attach the upholstery attachment to your vacuum cleaner and run it over the entire surface of the mattress. Pay close attention to the seams, corners, and edges where dust and debris tend to accumulate. Vacuuming helps remove loose dirt, dust mites, and allergens, creating a cleaner foundation for the subsequent cleaning steps.

Step 2: Spot Cleaning

Materials used: Stain remover, mild detergent, water, clean cloth.

If your mattress has any visible stains, it’s important to spot clean them before proceeding with the overall deep cleaning. Start by checking the manufacturer’s instructions for any specific cleaning recommendations. For general stains, create a mixture of mild detergent and water. Gently blot the stained area with a clean cloth, avoiding excessive moisture. For tougher stains, you can use a stain remover specifically designed for mattresses. Always test the cleaning solution on a small, inconspicuous area first to ensure it doesn’t damage the fabric.

Step 3: Deodorizing

Materials used: Baking soda, sieve or sifter.

Over time, mattresses can develop unpleasant odors. To deodorize your mattress, sprinkle a generous amount of baking soda over the entire surface. Use a sieve or sifter to distribute the baking soda evenly. Let the baking soda sit for at least a few hours, or preferably overnight. Baking soda naturally absorbs odors, leaving your mattress smelling fresh. Once the desired time has passed, vacuum the mattress again to remove the baking soda residue.

Step 4: Steam Cleaning

Materials used: Steam cleaner.

Steam cleaning is an effective method to deep clean and sanitize your mattress. Using a steam cleaner with an upholstery attachment, go over the entire surface of the mattress. The high temperature of the steam helps kill bacteria, dust mites, and other allergens, providing a thorough cleaning. Ensure that you follow the manufacturer’s instructions for your specific steam cleaner model.

Step 5: Drying

Materials used: Fan, sunlight.

After steam cleaning, it’s crucial to allow your mattress to dry completely before using it again. Open windows or use a fan to promote air circulation in the room. If possible, place the mattress in direct sunlight, as sunlight helps eliminate any remaining moisture and acts as a natural disinfectant. Ensure that the mattress is completely dry before putting on clean bedding.


Deep cleaning your mattress is an important task to maintain its cleanliness and extend its lifespan. By following the steps outlined in this article, you can effectively remove dirt, stains, and odors, creating a healthier sleeping environment. Remember to vacuum regularly, spot clean stains, deodorize with baking soda, steam clean, and allow for proper drying. By incorporating these steps into your mattress cleaning routine, you can enjoy a fresh and hygienic sleep surface.
