How to Deep Clean a Mattress (Because You Should Every 6 Months)


Who else is up for a whole new level of spring cleaning? We’re going to show you how to deep clean a mattress, so open those windows, roll up your sleeves, and get ready. The mattress is usually disregarded when it comes to cleaning, but it gets more use on a daily basis than most of our furniture. It’s time to start deep cleaning your mattress twice a year if you haven’t already. So, here’s how to clean a mattress deep.

Why should you clean your mattress deep?

When it comes to safeguarding beds from sweat, spills, and dust, sheets and mattress pads aren’t airtight. Consider this: sheets and pillowcases are washed every couple of weeks (every two weeks is ideal). So, if you’ve never cleansed your mattress, think about what’s underneath the surface, inside, and on top of it. Yikes.

Some allergies, colds, and illnesses have been linked to bedding and mattresses, according to studies. One-week-old Amerisleep reports sheets already contain more bacteria on them than a bathroom doorknob. According to one study, certain feathery pillows create ideal circumstances for fungus growth. According to another study, just changing from one side to the other in the middle of the night can release trapped dust and dirt particles into the air. Well…shoot.

The good news is that about to show you how to deep clean a mattress so you don’t have to worry about bacteria, skin cells, pet dander, dust mites, fungus, and more!

How to Clean a Mattress deep

This is the typical procedure for you if your mattress has no specific stains, odors, or pests to deal with.

  1. Remove the mattress pad or protector, as well as all of your bedding. (Invest in a mattress pad if you don’t already have one.) They may not be able to keep everything out, but they do provide some protection against mites and pathogens.)
  2. Using a newly sanitized upholstery vacuum attachment, vacuum the top and sides of the mattress. Slowly move in circles to collect as much as possible.
  3. Sprinkle a layer of baking soda on top of the mattress and let it sit for several hours. Add some sunlight if you can and leave it for a full 24 hours. Baking soda eliminates moisture, deodorizes, and breaks up dirt and grime. Mattress Insider recommends using a whole one-pound package of baking soda if this is your first time deep cleaning your mattress.
  4. With the attachment, vacuum once again to remove all of the baking soda.
  5. Open the windows or use a fan to ventilate the room.
  6. Clean the box spring and bed frame. Vacuum fabric headboards and wipe clean metal and wood frames.
  7. Replace the clean linen on the bed (which has been washed in hot water and dried on high heat as recommended by the Centers for Disease Control and Prevention).

Voila! This type of deep cleaning should be done every six months.

How can you get stains out of your mattress?

The addition of stains makes things a little more difficult, but not by much. You’re only adding a step or two to the clean deep cleaning process. You can spot clean the mattress before dusting it with baking soda and allowing it to sit overnight (or for a few hours).

  1. First, wipe out any remaining moisture with a clean cloth if the stain is fresh or still wet. Blot instead of rubbing.
  2. Choose or create the stain remover that is best suited to your stain. For example, removing stains from bodily fluids requires completely different solutions than removing stains from wine or tea.
  3. The solution should be sprayed onto a clean towel. According to Architectural Digest, don’t spray the cleaner (or water) straight on the mattress. You don’t want any moisture to accumulate on your mattress.
  4. To soak the stain, dab the towel on it. Avoid rubbing or circling the cloth. All you want to do is blot up and down. Rubbing the stain into the fibers simply makes it worse.
  5. Wet a new cloth with water and ring it out to make sure it isn’t damp or dripping (again, the less moisture the better).
  6. To soak the stain and the cleaner, dab the wet cloth against the stain.
  7. Allow to dry completely before adding the baking soda and vacuuming again.

Enzymatic cleansers and cold water are your best allies when dealing with body fluid (pet mishaps, menstrual stains, flu disaster). If you don’t have an enzymatic cleaner on hand, you may make your own with common household products. A spray bottle filled with equal parts water and vinegar works wonders on odorous stains like pet urine.

Hard-to-remove stains from food, beverages, or art supplies may benefit from steam cleaning. Steam cleaning can easily take the place of the second vacuuming stage. Use a steam cleaner that is designed for fabrics and porous surfaces. Dust mites may be killed by water or steam at temperatures above 70 degrees Fahrenheit, which is obviously a major benefit.

In general, hydrogen peroxide, distilled white vinegar, baking soda, laundry detergent, and dish soap can be mixed together to make effective remedies for a wide range of stains. Before dousing a whole piece of your mattress with your homemade (or store-bought!) cleaner, test it on a tiny area first. Isn’t it nice? You can use it whenever you want.

Pro tip: Regardless of the source, the sooner you address the stain, the easier it will be to totally remove it.

What is the best way to get rid of a mattress odor?

As previously noted, an enzymatic cleaner is great for removing lingering odors from an old spill, accident, or pet. Vinegar and water should suffice, but if you’re stuck for ideas, try this mixture from Mattress Insider:

  • 1 teaspoon distilled water
  • 1 teaspoon of vinegar
  • 1 teaspoon dishwashing liquid
  • 2 teaspoons of baking soda
  • 1 disinfectant drop

After that, spot treat the area with a significant amount of baking soda and leave it to sit overnight if possible before vacuuming it up. If the stench is caused by sweat or body odor, combine cornstarch and baking soda. Cornstarch, according to Mattress Insider, is good in drying up oils.

It’s absolutely fine to add a few drops of your favorite essential oil to these combinations or during the baking soda phase.

If necessary, professionals are available.

Some companies, such as Stanley Steamer, offer deep mattress cleaning. If you’ve done everything and still can’t figure out why an odor or stubborn stain persists, it might be worth investing in a professional cleaning before tossing your mattress out.

Here are a few more pointers on how to clean a mattress.

Because vacuuming is such an important element of a mattress deep clean, you may need to invest in one that is up to the task. According to Consumer Reports, the Dyson V6 Mattress Handheld Vacuum is nearly three times as effective as a conventional vacuum at sucking up dust.

Leave your sheets off for a few hours the next time you change them to allow your mattress to breathe. This is perfect if you can prop it up near a sunny, open window.

Warm, damp environments are ideal for mites, germs, fungi, and mold. Some of these small terrors can be killed by lowering the temperature in your bedroom by a few degrees.

Have you ever sat in bed with your laptop open? Have you ever slept with your phone next to your pillow? Those technological devices may also contain harmful germs and bacteria. Before climbing beneath the covers with them, wipe them down with disinfection wipes or sprays that contain at least 70% alcohol.

Mattresses from companies like Sleep Number and Casper may come with their own instructions for deep cleaning. Check with your manufacturer to ensure you don’t miss any important procedures or cautions.
