How to Remove Yellow Stains on a Mattress: A Comprehensive Guide

Waking up to the sight of yellow stains on a mattress can be quite alarming. But fear not! This guide will provide you with practical solutions to effectively deal with these stains and rejuvenate your mattress, ensuring it remains clean and hygienic.

As mattresses age, they naturally accumulate wear and tear, often resulting in unsightly yellow stains. These stains can originate from a variety of sources such as sweat, body fluids, dust, and the passage of time itself. It’s essential to address them promptly to uphold a healthy sleeping

Understanding the Cause of Yellow Stains

Before delving into cleaning solutions, it’s crucial to identify the root cause of the stain. Here are some common culprits:

  • Sweat and Body Fluids: Areas of frequent contact can lead to yellowish discolouration caused by sweat and bodily fluids.
  • Urine: Neglected urine stains can gradually turn yellow and emit unpleasant odours if not promptly addressed.
  • Dust and Dirt: Accumulated dust and grime over time can contribute to a yellowing effect on the mattress surface.
  • Age: With time, mattresses naturally degrade, leading to a general yellowing due to material breakdown.

Signs to Look For:

  • Color: The hue of yellow can provide insights. Light yellow tones may hint at sweat or dust accumulation, while deeper shades could imply urine stains or aging effects.
  • Odor: The persistent scent of urine is a clear indicator of a urine stain.
  • Location: Stains located near the head and foot of the mattress often stem from sweat, whereas those in the middle may indicate urine accidents

Preparing the Mattress for Cleaning

Essential Steps Before Cleaning

  • Bedding Removal: Remove all sheets, blankets, and mattress covers. Launder them in hot water with suitable detergent.
  • Vacuuming: Use a vacuum cleaner to meticulously clean the entire mattress surface, including crevices and seams, to eliminate loose dirt and dust.
  • Moisture Removal: If any moisture persists, promptly attend to it. Gently blot the affected area with a clean, absorbent cloth to prevent additional staining.

Natural Cleaning Solutions

Natural Stain Removal Methods

For minor yellow stains, environmentally-friendly cleaning remedies crafted from common household ingredients can prove quite effective.

  • Baking Soda: This multipurpose powder serves as a natural deodorizer and gentle abrasive. Sprinkle baking soda directly onto the stain and let it sit for several hours, ideally overnight, to absorb odours and lift dirt. Vacuum thoroughly afterwards.
  • Vinegar: The acidic properties of white vinegar aid in neutralizing certain stains. Combine equal parts white vinegar and water in a spray bottle. Lightly spray the affected area, allowing it to sit for 15 minutes. Blot with a clean, damp cloth, and allow the mattress to air dry completely.

Important Note:

Before applying any cleaning solution, it’s essential to conduct a patch test on an inconspicuous area of the mattress to ensure it doesn’t cause discolouration.

Enzyme Cleaners

Enzyme Cleaners for Tough Stains

When dealing with organic matter-based stains such as sweat or urine breakdown, enzyme cleaners provide a potent solution.

  • Enzyme cleaners: These natural products contain enzymes that break down organic materials, effectively removing stains and persistent odours. Follow the manufacturer’s instructions for application and rinsing.

Spot Treatment

Applying the Cleaning Solution

After identifying the stain and selecting your preferred cleaning approach, it’s time for precise action:

  • Apply the selected solution: For natural cleaning methods, employ a spray bottle to lightly mist the stained area or form a paste using baking soda mixed with a small amount of water. Follow the product instructions when applying the enzyme cleaner.
  • Gently agitate: If utilizing a paste or baking soda, softly brush the cleaning agent into the stain using a soft brush. Refrain from vigorous scrubbing, as it may harm the mattress fabric.

Patience is Key:

Let the cleaning solution sit on the stain for the prescribed duration, typically 15-30 minutes for natural remedies and according to the instructions provided for enzyme cleaners.


Removing Cleaning Residue

Following the stain treatment, it’s essential to eliminate any remaining cleaning product residue:

  • Vinegar Rinse: Combine one tablespoon of white vinegar with one cup of water. Dip a clean cloth into the solution, ensuring it’s thoroughly wrung out. Delicately wipe the area to remove any remnants of the cleaning solution.

Deep Cleaning for Stubborn Stains

  • Cleaning Paste: Baking Soda and Hydrogen Peroxide Paste: Form a paste by mixing baking soda and hydrogen peroxide (3 parts baking soda to 1 part hydrogen peroxide). Apply the paste directly onto the stain and let it sit for several hours. Use a soft brush to gently scrub the area, then rinse thoroughly with clean water.  Warning: Avoid mixing hydrogen peroxide with vinegar, as it can produce a harmful gas.
  • Professional Cleaning Services: For stubborn stains or those resistant to DIY approaches, professional mattress cleaning services are recommended. Experts possess the knowledge and tools to effectively tackle deep-seated stains and ensure a comprehensive cleaning.

Drying and Airing

Preventing Mold and Mildew Growth

After completing the cleaning process, thorough drying is essential to prevent the growth of mould and mildew:

  • Air Circulation: Ensure proper air circulation by opening windows and doors.
  • Fan Assistance: Employ fans to accelerate the drying process.
  • Sun Exposure (Optional): If weather permits, briefly expose the mattress to direct sunlight for extra drying effectiveness. Caution: Avoid prolonged sun exposure, as it may harm the mattress fabric.

Preventing Future Stains

Preventing Yellow Stains from Returning

  • Mattress Protection: Consider investing in a waterproof and breathable mattress protector. This layer shields against spills, sweat, and dust, significantly minimizing the risk of stains.
  • Regular Maintenance: Vacuum the mattress surface regularly to eliminate dust and allergens.
  • Moisture Management: If you suspect moisture issues such as condensation or leaks, address them promptly to prevent further staining and potential mould growth.


Dealing with yellow stains on a mattress can be effectively managed with the right strategy. By identifying the stain’s origin, selecting the appropriate cleaning technique, and ensuring thorough drying, you can rejuvenate your mattress to a clean and hygienic condition. Remember, prompt stain treatment and implementing preventive measures such as mattress protectors are essential for maintaining a healthy sleep environment.
