Your mattress might look clean on the surface, but over time it collects sweat, dust, and odors that regular sheets can’t protect against.

If you’ve been wondering how to refresh it without expensive sprays or deep cleaning machines, there’s one simple, natural trick: baking soda.

How It Works

Baking soda (sodium bicarbonate) is a natural deodorizer and moisture absorber.
When you sprinkle it over your mattress, it helps:

Absorb excess moisture from sweat or humidity

Neutralize odors caused by bacteria

Break down dirt and oils trapped in the fabric

It’s gentle, chemical-free, and completely safe for kids and pets.

How to Do It: Step-by-Step

Strip the bed – remove all bedding and pillows.

Sift or sprinkle baking soda evenly across the entire surface of the mattress.

For best results, use a fine-mesh sieve or strainer.

You can add a few drops of essential oil (like lavender or eucalyptus) to the baking soda before sprinkling for a light scent.

Let it sit for at least 30 minutes to 2 hours — or even longer if possible.
The longer it sits, the more odor and moisture it absorbs.

Vacuum it up using the upholstery attachment on your vacuum cleaner.
Make sure to remove all powder residue.

Air it out for a few minutes before remaking your bed.

Bonus Tip

Do this every 2–3 months to keep your mattress fresh and hygienic.
If you live in a humid area, sprinkle baking soda more often to prevent musty smells.
You can also use the same trick on sofas, rugs, and fabric chairs.

Why It Works So Well

Mattresses can’t be washed, so over time they naturally trap body oils, dead skin cells, and moisture.
Baking soda’s natural alkaline properties neutralize acids and odors, while its texture gently lifts grime without damaging fabric fibers.

It’s a zero-cost, zero-effort way to deep clean the one piece of furniture you use most every day.

In Short

A little baking soda can make your mattress smell clean, feel fresh, and last longer — no chemicals, no steam cleaners, no hassle.

Try it once, and you’ll never skip it again. 🌿
