How to Clean a Yellowed Mattress: Effective and Natural Methods

Even the best mattresses can turn yellow over time. If you've noticed yellow stains on your bed, you're not alone. Sweat, body oils, moisture, and dust are the main causes of this discoloration. In addition to being unsightly, these stains can harbor bacteria and allergens that can be harmful to your health and sleep quality.

In this article, discover simple and effective methods for cleaning a yellowed mattress and keeping it clean, healthy and durable.

Why Does a Mattress Turn Yellow?

Before moving on to cleaning, it's helpful to understand the common causes of yellowing:

• Perspiration and natural sebum
• Dead cells and mites
• Humidity and poor ventilation
• Aging of materials, especially foam
• Prolonged exposure to UV rays

These elements accumulate over time, especially on the surface and edges of the mattress.

Steps to Clean a Yellowed Mattress

1. Vacuum thoroughly

Remove all bedding and vacuum the mattress with a brush attachment. Remember:

• The complete surface
• Seams and corners
• The underside of the mattress if possible

This removes dust, dirt and dander before wet cleaning.

2. Clean stains with vinegar and baking soda

Prepare a natural solution:

• 1 cup white vinegar
• 1 tablespoon of baking soda
• 1 cup of warm water

Spray lightly on the yellowed areas (do not soak the mattress), then dab with a clean microfiber cloth. The vinegar degreases and disinfects, while the baking soda neutralizes odors.

Leave on for 30 minutes before wiping.

3. For deep stains: hydrogen peroxide

For old brands:

• 1 cup of hydrogen peroxide (3% hydrogen peroxide)
• 1 tablespoon of dishwashing liquid
• 1 tablespoon of baking soda

Apply this mixture to the stains with a spray bottle or sponge. Let it lather for 10 minutes, then dab with a damp cloth. Very effective on memory foam mattresses.

4. Deodorize with dry baking soda

Sprinkle dry baking soda over the entire mattress. Let it sit for 4 to 6 hours (or overnight for best results), then vacuum thoroughly.

This absorbs moisture and neutralizes odors naturally.

Specific advice for a Morphea mattress

If you own a Morphea mattress (hybrid or memory foam), you already have an advantage: these models use certified, breathable materials that are more resistant to deep stains.

To maintain them:

• Use the removable cover: Most Morphea mattresses come with a machine-washable cover.
• Air regularly: let the mattress breathe without sheets for a few hours every 2-3 months.
• Turn it over every 3 to 6 months: this distributes wear and limits humidity.

Preventing Mattress Yellowing

• Protect it with a waterproof mattress protector
• Wash your sheets every week
• Control humidity with a dehumidifier if necessary
• Avoid letting pets sleep on it (hair and sebum make stains worse)

When should the mattress be replaced?

If your mattress is more than 8 years old and remains yellowed despite regular cleaning, it may be time to replace it. Prolonged moisture and bacteria can deteriorate the foam, affect your sleep, and cause allergies.
