How to clean a used mattress?


Cleaning a used mattress is an essential task to ensure a healthy and hygienic sleeping environment. When purchasing a second-hand mattress, it is crucial to clean it thoroughly to remove any dirt, allergens, or bed bugs that may be present. In this article, we will explore the step-by-step process of cleaning a used mattress to help you maintain a clean and comfortable sleeping surface.

Step 1: Vacuuming

Materials used: Vacuum cleaner with upholstery attachment, baking soda.

The first step in cleaning a used mattress is to thoroughly vacuum it. Start by attaching the upholstery attachment to your vacuum cleaner. Use the attachment to vacuum the entire surface of the mattress, paying extra attention to the seams and crevices where dust and dirt tend to accumulate. This will help remove any loose debris and dust mites.

Step 2: Spot Cleaning

Materials used: Mild detergent, warm water, clean cloth or sponge.

After vacuuming, it’s time to spot clean any stains or spills on the mattress. Create a solution of mild detergent and warm water. Dip a clean cloth or sponge into the solution and gently blot the stained area. Avoid saturating the mattress with water, as it can lead to mold or mildew growth. Continue blotting until the stain is lifted, then allow the mattress to air dry.

Step 3: Deodorizing

Materials used: Baking soda.

To remove any odors from the mattress, sprinkle a generous amount of baking soda over the entire surface. Baking soda is a natural deodorizer and will help absorb any unpleasant smells. Leave the baking soda on the mattress for at least a few hours, or overnight if possible. Then, vacuum the mattress again to remove the baking soda residue.

Step 4: Disinfecting

Materials used: Rubbing alcohol, spray bottle.

To disinfect the mattress and kill any remaining bacteria or bed bugs, fill a spray bottle with rubbing alcohol. Lightly mist the entire surface of the mattress with the alcohol, focusing on areas that may be more prone to bacteria buildup, such as the corners and edges. Allow the mattress to air dry completely before moving on to the next step.

Step 5: Mattress Protector

Materials used: Mattress protector.

To maintain the cleanliness of your mattress in the long run, consider using a mattress protector. A mattress protector acts as a barrier against spills, stains, and allergens, helping to extend the lifespan of your mattress. Choose a waterproof and hypoallergenic mattress protector that fits your mattress size.


Cleaning a used mattress is a crucial step in ensuring a healthy and hygienic sleeping environment. By following the step-by-step process outlined in this article, you can effectively remove dirt, stains, and allergens from your mattress. Regular cleaning and maintenance will not only prolong the life of your mattress but also contribute to a better night’s sleep.
