How To Clean Mattress With Baking Soda And Vinegar: Step‑By‑Step FAQ

If you’re searching for how to clean mattress with baking soda and vinegar, you’re likely dealing with stains, smells, or just general mattress freshness. This guide walks through exactly how to do it safely and effectively, with clear answers to the most common questions.

What does cleaning a mattress with baking soda and vinegar actually do?

Using baking soda and vinegar on a mattress is a simple home method that can:

  • Help lift light stains from the surface
  • Neutralize odors from sweat, spills, or everyday use
  • Freshen the mattress between deeper cleanings

Vinegar acts as a mild, acidic cleaner that can help break down some types of stains. Baking soda helps absorb moisture and odors. Together, they create a basic surface refresh, not a full restoration for heavily damaged mattresses.

How To Clean Mattress With Baking Soda And Vinegar: Basic Step‑By‑Step

Here is a straightforward process many people use at home:

  1. Strip the bed
    Remove all sheets, protectors, and bedding so the mattress surface is fully exposed.

  2. Vacuum the mattress
    Use the upholstery attachment to remove dust, crumbs, and loose debris. Focus on seams and crevices.

  3. Spot‑treat stains with vinegar

    • Mix equal parts white vinegar and cool water in a spray bottle.
    • Lightly mist the stained area (do not soak the mattress).
    • Gently blot with a clean, white cloth. Avoid scrubbing hard, which can spread the stain.

  4. Apply baking soda

    • While the treated areas are still slightly damp, sprinkle a thin, even layer of baking soda over the surface.
    • For odor‑heavy spots, you can very gently work the baking soda in with your fingertips.

  5. Let it sit
    Allow the baking soda to rest on the mattress for at least a few hours. Many people leave it for most of the day. The longer it sits, the more odor and moisture it can absorb.

  6. Vacuum again
    Thoroughly vacuum up all the baking soda. Go slowly to remove as much powder as possible.

  7. Allow to air dry
    Let the mattress air out completely before putting bedding back on. Good airflow and time are important so no moisture gets trapped.

Is it safe to use vinegar directly on a mattress?

In small amounts, diluted white vinegar is commonly used on mattresses, but there are a few points to keep in mind:

  • Use lightly, never soak the mattress. Excess liquid can get trapped inside and be difficult to dry.
  • Always test a small, hidden area first to make sure there is no discoloration.
  • Avoid using vinegar on materials that are clearly labeled as “dry clean only” or that come with specific cleaning instructions from the manufacturer.

If your mattress has a care tag, it’s helpful to check it before using any cleaning method.

Can baking soda and vinegar remove all types of mattress stains?

Not always. Baking soda and vinegar may help with:

  • Light sweat stains
  • Some food or drink stains (especially if cleaned quickly)
  • General odor buildup

However, they may not fully remove:

  • Old, deeply set stains
  • Certain colored liquids
  • Stains that have been scrubbed or treated with multiple products in the past

In those cases, this method can still reduce discoloration and smells, but the stain may remain faintly visible.

How long should I leave baking soda on the mattress?

For most situations:

  • Minimum: 1–2 hours
  • Better: 4–8 hours
  • Overnight: Often preferred if the odor is strong and you have the time

The longer the baking soda stays on the surface, the more moisture and odor it can absorb, as long as the room is reasonably dry and well‑ventilated.

Will my mattress smell like vinegar afterward?

A light vinegar smell is common right after cleaning, but it usually fades as it dries. Baking soda also helps neutralize the odor.

To reduce lingering smell:

  • Use diluted vinegar, not full‑strength
  • Keep windows open or fans running for better airflow
  • Make sure the mattress is fully dry before remaking the bed

If a slight scent remains, it typically becomes weaker over the next day or so.

How often should I clean my mattress with baking soda and vinegar?

For general freshness, many people:

  • Use baking soda and vacuuming every few months
  • Reserve vinegar spot‑treatments for visible stains or specific spills

Light, regular maintenance often makes stains easier to address if they happen later.

Are there any mistakes to avoid with this cleaning method?

A few common issues to watch for:

  • Using too much liquid: Soaking the mattress with vinegar or water can trap moisture inside.
  • Not vacuuming thoroughly: Leftover baking soda can feel gritty and may work its way into sheets.
  • Skipping drying time: Putting bedding back on a damp mattress can create a stuffy, unpleasant smell over time.
  • Ignoring the care label: Some mattresses have specific cleaning instructions that should take priority.
