How to Clean Your Mattress and Keep It Brand New

Last Updated: June 12, 2022

What’s inside your mattress? Learn how to clean your mattress and keep it looking — and feeling — brand new for longer with our quick ‘n’ easy guide.

The average person spends a whopping third of their life sleeping — or attempting to sleep. In that time, your mattress comes into contact with sweat, body oil, dirt, dead skin cells, various body fluids, pet dander, as well as dust and allergens from your surroundings.

Regardless of how clean you and your sheets are, oils and debris still make their way inside your mattress. Once inside, they create odors and provide a warm home for microscopic organisms to breed and feast. Ick.

We’ve put together an in-depth guide with the best ways to clean your mattress and keep it feeling brand new.

What you’ll need to clean your mattress

How to clean your mattress

1. Wash your sheets

First things first, wash your bedsheets with a plant-based detergent. If it’s been a few months — or you’ve never done it before — wash your pillows, too.

2. Vacuum

Vacuum the entire mattress to remove any dust and debris. Make sure to get the sides of the mattress, and pull the fabric taut to get any particles that are hanging out in the crevices.

3. Spot clean

  1. Mix a few drops of natural dish soap in a bowl filled with water.
  2. Dip a microfiber cloth into the mixture and dab any areas that need a lil’ TLC, like darkened spots or spots with sweat stains.
  3. Dip another cloth into a bowl filled with clean water and dab away the soapy mixture.
  4. Repeat until all stains are removed and let the mattress air dry.

4. Deodorize

Sprinkle a fine layer of baking soda over the surface of your mattress. Baking soda absorbs odors and moisture, and helps keep your mattress fresh. Let the baking soda sit for three to five hours.

Pro tip: pop open the windows to allow extra air flow while the baking soda does its job.

5. Vacuum, pt. 2

Vacuum the baking soda off of your mattress. That’s it! Your mattress is fresh, clean, and ready to be slept on.

Grove Tip

Hydrogen peroxide for gnarly stains

For extra icky stains — like blood, urine, and vomit — mix equal parts hydrogen peroxide and water in a small bowl. Take a clean microfiber cloth and dab the stained area with the hydrogen peroxide mixture. Let the mattress air dry and repeat the process if the stain remains.
