How to Deep Clean Your Mattress

Mattresses are the most hardworking furniture in your home, yet they are rarely cleaned despite housing skin cells, dust mites, and sweat. A proper deep clean twice a year refreshes the sleep surface, extends the lifespan of the mattress materials, and significantly improves indoor air quality in your bedroom. Done well, a mattress cleaning feels like a reset button for your sleep hygiene. It is not about harsh scrubbing or saturating the fabric, but rather about gentle extraction and odor management. By the time you are finished, you will have a sanitized, neutral-smelling bed that feels significantly lighter and fresher to the touch.

1. Strip and launder everything. Remove all linens, mattress protectors, and pillows. Wash bedding in the hottest water setting the fabric allows to kill bacteria and dust mites.
2. Extract hidden dust thoroughly. Use your vacuum's upholstery attachment to go over the entire top surface of the mattress. Focus on the seams and tufting, as these areas collect the most dust and skin cells.
3. Blot stains with restraint. Mix a mild solution of dish soap and cold water. Dab the stain with a clean white cloth, using as little moisture as possible to prevent mold growth in the foam.
4. Neutralize odors naturally. Sift a thin, even layer of baking soda across the entire surface of the mattress. Use a soft-bristled brush to gently work the powder into the fabric without damaging the top layer.
5. Remove all baking soda traces. Once the baking soda has sat, use the upholstery tool to vacuum every inch of the mattress again. Ensure no white powder remains in the crevices.
6. Rotate and refresh underside. Rotate your mattress 180 degrees to ensure even wear across the springs or foam core. Repeat the vacuuming and deodorizing process on the underside.
