How to Disinfect Your Mattress

Here is a step-by-step guide on how to disinfect a mattress, including the tools and cleaners you will need:

Tools you will need:

Steps to Disinfect:

  1. Remove all bedding and pillows from the mattress.
  2. Vacuum the mattress thoroughly, paying attention to the seams and edges. This will remove dust, dirt, and any loose hair or dander.
  3. Use a steaming machine for upholstery. Hold the nozzle about 6 inches above the mattress and start moving back and forth to cover the entire mattress. Be careful not to oversaturate the mattress with steam.
  4. Let the mattress sit in the sunlight or use a fan to speed up the drying process.
  5. Once dry, you can use a dust mite vacuum to take away the unseen dust mites from your mattress.
  6. Spray your disinfecting surface cleaner or an enzyme cleaner on your mattress.
  7. No need to rinse! Just let it air dry completely.
  8. If you have a portable UV light, you can pass it through the surfaces of your mattress.

Here are some additional tips for drying a mattress after steaming:

  • If you have a memory foam mattress, you may want to avoid using a fan. The fan can dry out the memory foam and make it uncomfortable.
  • If you have a waterbed, you will need to use a special mattress dryer that is designed for waterbeds.
  • Be careful not to oversaturate the mattress with steam. This can cause the mattress to become damp and moldy.

How to Spot Treat Stains on Your Mattress

Now you know how to disinfect your mattress. But what if you’re only looking to treat spot stains and not your whole mattress? Here’s what you need to do based on the type of stain.

The first thing you need to do is to soak up or blot the stain with a microfiber cloth or paper towel. Do this immediately to avoid the stain from setting.


Mix a solution of equal parts vinegar and water in a spray bottle. Spray the affected area with the solution and let it sit for about 15 minutes. By this time, the vinegar will have evaporated. Sprinkle some baking soda on the spot and let it sit overnight. Vacuum the baking soda and you’re done! 

If you have a memory foam mattress, you may want to avoid using baking soda. Baking soda can dry out the mattress and make it uncomfortable.


If the mattress is freshly stained, the blood will soak better onto cloth washed in cold water. Make a paste using baking soda and some cold water. Spread that paste directly on the stain and let it sit for about 30 minutes. You can remove the paste later without scrubbing it. To make your mattress look new, use a mixture of hydrogen peroxide with two parts cold water in a spray bottle. Spray the affected area and let it sit for about 15 minutes. Allow it to air dry.

Baby stains

Babies can leave drool, urine, and poop on the bed by accident. After removing the visible, removable dirt, vacuum it. Then use a baby-safe disinfecting solution and leave it to air dry. If there is visible staining, use Puracy’s Natural Baby Stain Remover on any washable fabric and put it in the washer.

If the stain is directly on the mattress, spray the affected area with the baby stain remover then wait for 15 minutes. Fill a basin with warm water and soak a washcloth in it. Wring the cloth and blot it on the treated spot. Do this repeatedly to “rinse” off the stain remover.


Mild stains like sweat can be treated the same way you treat urine stains. Learn how to disinfect your mattress using vinegar and water on a spray bottle. Follow the instructions on treating urine stains.


When treating mold stains, it’s best to wear hand and eye protection. You can also cover your nose and mouth with a mask. To treat molds, use rubbing alcohol on a cloth and gently rub the stained surface. Sometimes, mold problems may be deeper than they look. Consult with a professional for proper disinfection. Don’t forget to wash the bedsheets and pillowcases in high temperatures.

Pet Stains

It’s not impossible for pets to leave unsightly stains and odors. For urine stains, follow the same steps mentioned under “urine”. You can also add a drop of liquid detergent or a mild dish soap to the mixture. Vacuum the area until it’s fresh again.

How to Remove Odor From the Mattress

Unwanted odors on a mattress can be caused by various sources, such as sweat, spills, body oils, pet dander, or even mildew. Here's a step-by-step guide on how to remove these odors.

To make sure the odors are removed, you can disinfect the mattress using the methods stated in the previous section and use the following steps as a guide:

  • Identify the source 
  • Determining the source of the odor is the first step in disinfecting your mattress. Is it due to sweat, spills, pet dander, or something else? This will help you choose the appropriate treatment.

  • Basic preparations
  • Before you start using an antibacterial disinfectant, remove all bedding and covers from the mattress. Open windows and doors to ensure good ventilation in the room.

  • Vacuuming
  • Thoroughly vacuum the mattress using an upholstery attachment to remove loose dirt, dust, and debris. Pay special attention to seams, crevices, and corners.

  • Use the appropriate disinfecting method
  • Disinfect your mattress using the steps mentioned in the previous section, depending on the type of stain you’re dealing with. Use baking soda or cornstarch as a natural deodorizer by sprinkling a generous amount on the mattress to neutralize any odors. Then vacuum the baking soda.

  • Sunlight treatment to kill the bacteria
  • If possible, place the mattress in direct sunlight for a few hours. Sunlight can help kill bacteria and freshen the mattress. Make sure to flip the mattress to expose both sides.

  • Use a mattress protector
  • Consider using a mattress protector to prevent future odors and stains. These protectors are easy to get in the washer and can add an extra layer of defense against spills and allergens.

    How to Get Rid of Parasites From Your Mattress

    Parasites are tiny organisms that can live in your mattress and cause a variety of health problems. Some of the most common parasites found in mattresses include bed bugs, dust mites, ticks, and fleas. These problems are easily avoidable if you know how to disinfect your mattress routinely.

    If you think you may have parasites in your mattress, there are a few things you can do to find and treat them:

    1. Look for signs of infestation

    Bed bugs and ticks leave behind dark spots of excrement, while dust mites leave behind tiny white specks. Fleas may also leave behind small, red bumps on your skin.

    2. Vacuum your mattress thoroughly

    Use a vacuum with a hose attachment to get into all the nooks and crannies of your mattress.

    3. Sprinkle baking soda on your mattress

    Baking soda is a natural desiccant that can help to kill parasites. Let the baking soda sit on your mattress for 24 hours, then vacuum it up.

    4. Use a mattress protector

    A mattress protector can help to prevent parasites from getting into your mattress in the first place.

    5. Call a professional exterminator

    If you have a severe infestation, you may need to call a professional exterminator to get rid of the parasites.
