How to Remove Odor From a Mattress

From a mattress cleaner to home remedies, getting rid of mattress odors can be easy.

Just like your clothing, a mattress can get smelly from repeated use. Unlike your clothing, you can’t just throw a mattress into the washing machine.

This can be a problem when you have pets, a sweaty sleep partner, a partner who smokes, or possibly a child who isn’t yet potty trained.

So how do you deodorize a mattress?

The question is trickier than it may seem. This is because harsh chemicals can potentially leave you breathing in unhealthy fumes when you sleep. Instead, you'll want a milder solution that is still effective. Here are some helpful tips we’d recommend trying every six months:

NOTE: Always first check with your mattress manufacturer for a list of safe cleaning methods. Also, try any new cleaning method on a small portion of the mattress (like a corner) before using it on the entire mattress:

Vacuuming the Mattress:

After completely stripping the bed, a good first step is to vacuum the mattress with a high quality, powerful vacuum using the upholstery attachment. Make sure to get into all the seams and crevasses, and give the sides a good once-over as well. For an extra thorough job, flip the mattress over and vacuum the bottom.

Distilled White Vinegar:

Instead of a chemical mattress cleaner, many have found great results mixing equal parts water and distilled white vinegar in a spray bottle. Lightly spray the surface of the mattress just enough to dampen it, but not enough to saturate it. Then let it air dry over the course of a day.

Baking Soda:

A popular method to remove odor from a mattress is to sprinkle baking soda on it. Use as much as you want, and make sure to evenly distribute it over the entire top surface of the mattress. Let it sit for a day, and if you can, open the curtains to let some direct sunlight help the baking soda work its magic. Then in the evening, vacuum it up.

Corn Starch:

Lots of people swear by corn starch as a means to clean urine from a mattress, including its smell. Simply sprinkle the cornstarch over the spot where the accident occurred, and top it off with a few drops of water. Wait five minutes, then remove the cornstarch and blot the spot with a paper towel.

In addition, many recommend corn starch used in conjunction with the baking soda. Simply sprinkle them on at the same time, and the baking soda will remove odors while the cornstarch absorbs body oils. After letting them sit for the day, vacuum them up before bed.

Launder the Bedding:

While you are cleaning the mattress, throw all the sheets, pillowcases, etc. into the washing machine. Wash them on the highest allowable temperature setting, then tumble dry for at least 30 minutes to ensure dust mites and other unwanted creatures are killed.

Use a Waterproof Mattress Encasement:

One of the best ways to get odors out of a mattress is to prevent them from getting in. A waterproof mattress protector guards against odor-causing surface stains from spills and accidents. In addition, a mattress encasement prevents spilled liquids from seeping deep into the mattress fibers where smelly mold and mildew can grow.
