How to Remove Yellow Stains from Mattress

Are there yellow stains on your mattress? They’re more common than you might think, especially if your mattress has been around for a while. Even the best mattresses can develop these unsightly and unhygienic stains over time if not adequately protected and regularly cleaned.

Wondering what causes these yellow stains and how to get rid of them? Keep reading to discover how to clean these stains and learn when it might be time to replace your old, stained mattress.

What Causes Yellow Stains on a Mattress?

The yellow stains on your mattress can be caused by various factors. The primary culprit is often oxidation due to the mattress’s aging process. However, there could be other reasons for the unsightly stains on your mattress. Let’s explore the most common causes:

  1. Natural Oxidation: As mattresses age, they naturally undergo decay, mainly due to oxidation caused by exposure to oxygen in the air. This process gives the aging mattress a yellowish tint. These yellow stains from oxidation don’t have a smell and persist even with regular cleaning. To slow down oxidation, it’s advisable to keep the mattress away from moisture and direct sunlight.
  2. Urine: Both human and pet urine can lead to smelly yellow stains on your mattress. It’s crucial to clean fresh urine promptly to prevent it from penetrating deeper into the mattress. Once dried, it becomes challenging to remove both the stains and the odors. Untreated urine stains may also result in mold and mites, further deteriorating the mattress.
  3. Sweat and Body Oil: Over time, everyone sweats and releases natural body oils during sleep. While sweat stains may not appear immediately, they accumulate and form unsightly stains over time. The accumulated sweat provides an ideal environment for bacteria to grow, leading to unpleasant odors along with the staining. Regularly washing and changing your bedding can help prevent these smelly sweat stains.
  4. Vomit: Similar to urine, vomit from humans and pets can cause smelly yellow stains if not cleaned up promptly. It’s essential to remove as much as possible before dabbing the area to eliminate excess moisture. Disinfect the area with rubbing alcohol and use a few drops of essential oil to get rid of unpleasant odors.
  5. Rust: Water and sweat reaching the coils of spring or hybrid mattresses may cause the springs to rust. Rust stains are distinguishable by their darker color and orange tinge. They may also have a faint metallic smell.
  6. Water Stains: Spilling water on your mattress without immediate cleanup can result in light yellow-beige stains. While these stains are odorless, they can eventually lead to mold and more yellow stains if not addressed promptly.

How to Clean Yellow Stains from a Mattress

Once you’ve successfully dealt with the yellow stains on your mattress, it’s crucial to follow up with a thorough cleaning to prevent lingering odors and potential bacterial growth.

1. Vacuuming: Start by vacuuming the entire mattress using the upholstery attachment to eliminate any dust or dirt. This step is especially important if you’ve used baking soda, ensuring all residue is effectively removed.

2. Sanitizing: Consider using a mattress sanitizing spray to eliminate bacteria or germs. You can find these sprays at most home goods stores, or you can create your own by mixing equal parts water and rubbing alcohol with a few drops of essential oil for a pleasant fragrance.

3. Drying: After treating your mattress, ensure it’s completely dry before remaking the bed. A damp mattress can lead to mold and mildew, causing more significant problems. Speed up the drying process by using a fan, dehumidifier, or simply allowing the mattress to air dry for 24 hours.

Taking these steps will not only help maintain a fresh and clean mattress but also contribute to a healthier sleep environment.

Is Sleeping on a Mattress with Yellow Stains Safe?

No, it’s not safe to sleep on a mattress with yellow stains. While some yellowing can occur naturally over time, if your mattress smells odd or has noticeable stains, it could pose health risks. If you experience allergies like sneezing, coughing, or itching during sleep, your stained mattress may be the culprit.

Mold and dust mites could be thriving on these stains, potentially triggering allergic reactions, lung inflammation, and asthma attacks. If your mattress has persistent stains and your allergies persist, it’s no longer safe for sleep.

When It’s Time to Replace Your Mattress

Yellow stains from natural oxidation are generally harmless, but other factors can lead to serious health problems. Consider replacing your mattress if:

  1. There are permanent dips in your mattress.
  2. You regularly wake up with aching muscles.
  3. You haven’t cleaned your mattress for an extended period.
  4. You experience breathing issues while sleeping.

Yellow Stains as a Sign to Change Mattresses:


While some yellow stains can be cleaned, others are permanent. Cleaning can only do so much for a tired, stained mattress. If your mattress has stubborn yellow stains despite your efforts, it’s time to replace it with a new one.

A good replacement mattress will provide proper support for your body and ensure a restful night’s sleep. Explore options with your preferred mattress manufacturer to find the type that best suits your sleeping needs.
