How To Get Stains Out Of Mattress With Baking Soda: Simple FAQ Guide
If you’re wondering how to get stains out of mattress with baking soda, you’re not alone. Accidents happen, and mattresses are hard to wash in the traditional way. Baking soda is a common household ingredient that can help lift stains and reduce odours without harsh chemicals.
Below you’ll find clear, step‑by‑step answers to the most common questions about using baking soda for mattress stains.
What makes baking soda useful for mattress stains?
Baking soda is a mild abrasive and natural deodorizer. On mattresses, it can help:
- Absorb moisture from fresh spills
- Loosen light surface stains
- Neutralize lingering odours
It works best on fresh or mild stains and as part of a broader cleaning routine, rather than as a miracle fix for every type of damage.
How do I get fresh stains out of a mattress with baking soda?
For new spills or stains (like a drink or a small accident), act quickly:
Blot, don’t rub
- Use a clean, dry cloth or paper towels.
- Gently press to soak up as much liquid as possible.
- Avoid scrubbing, which can push the stain deeper.
Apply a gentle cleaning solution (optional but helpful)
- Mix a small amount of mild dish soap with cool water.
- Lightly dab the stained area with a cloth dampened in this solution.
- Blot again with a clean, dry cloth to remove excess moisture.
Sprinkle baking soda generously
- Cover the damp, stained area with a thick layer of baking soda.
- The baking soda helps draw out moisture and odour from the mattress.
Let it sit
- Allow the baking soda to sit for at least several hours, or ideally overnight.
- The longer it sits, the more moisture and odour it can absorb.
Vacuum thoroughly
- Use a vacuum with an upholstery attachment.
- Go slowly to remove all the baking soda from the surface and crevices.
If the stain is still visible, you can repeat the process once more.
Can baking soda remove old or set-in stains?
Baking soda alone may not fully remove deep, old, or heavily set-in stains, but it can still help improve their appearance and smell.
For older stains:
- Lightly mist the area with water or a mild soap-and-water mix.
- Sprinkle a generous amount of baking soda over the damp area.
- Gently press the baking soda into the fabric with your hand or a soft brush.
- Let it sit for 8–12 hours if possible.
- Vacuum well.
You may see lightening of the stain and less odour, but very dark or long‑standing stains might not disappear completely. In those cases, baking soda is often used as a first step before considering more targeted stain treatments or professional cleaning.
How To Get Stains Out Of Mattress With Baking Soda for Different Stain Types?
Can I use baking soda for sweat or general yellowing?
Yes, baking soda is commonly used to freshen a mattress that has mild yellowing from sweat or age.
- Lightly spray the surface with water (do not soak).
- Sprinkle baking soda over the discoloured areas.
- Leave for several hours.
- Vacuum thoroughly.
This can help brighten the surface slightly and reduce odour, though heavy yellowing may only improve, not vanish.
What about food or drink stains?
For spilled drinks or food:
- Blot up as much as you can immediately.
- Use a mild soapy water solution to gently dab the spot.
- Apply baking soda on the damp area and let it sit.
- Vacuum once it’s fully dry.
Avoid hot water, which can sometimes set certain stains more firmly into the fabric.
Is baking soda safe for all mattress types?
Baking soda is generally considered gentle and suitable for most mattress materials, including foam and hybrid designs, as long as you:
- Avoid soaking the mattress with water
- Allow plenty of drying time
- Vacuum thoroughly to remove residue
If your mattress has a care label, check any special cleaning instructions. Some covers are removable and washable, while others should only be spot cleaned.
How long should baking soda stay on a mattress?
For basic deodorizing, some people leave baking soda on for 1–2 hours. For stain treatment, longer is usually better:
- Fresh stains: several hours or overnight
- Older stains or strong odours: 8–12 hours
The key is to let the baking soda dry fully and absorb moisture before you vacuum it away.
How often can I clean my mattress with baking soda?
Many sleepers use baking soda:
- As needed for spills or accidents
- Every few months to freshen the surface
Sprinkling a light layer of baking soda over the whole mattress, letting it sit for a few hours, and vacuuming can help control general odours and minor surface discoloration over time.
