How to Combat Yellowing of Pillows

Do you ever wonder why your pillow's filling turns yellow and stains the pillowcase after a period of use, even if you carefully cover it with an outer pillowcase? We all know how important it is to have a good night's sleep, and maintaining hygiene and aesthetics of your pillow is key. Let's take a look at what is causing this, and how we can potentially fix it.


Pillows are an essential item that we use on a daily basis. Therefore, it is crucial to maintain their hygiene and aesthetics for a comfortable sleep experience. If you pay attention, you will notice that pillow fillings often turn yellow and stain the pillowcases over time, even with careful use of outer pillowcases. So, what causes this phenomenon? And how can it be fixed? Let’s explore the reasons and solutions.

The Causes of Yellow Stains on Pillows and How to Handle Them

The main cause of yellow stains on pillows is sweat. Specifically, the pillow filling absorbs sweat from the scalp, face, and other dirt during use. Over time, these accumulated dirt particles form yellow stains on the pillows.


This phenomenon occurs in everyone. However, individuals who sweat excessively during sleep may notice thicker and darker yellow stains on their pillows compared to others. The main culprit behind these stains is urea, a chemical found in sweat. Over time, urea breaks down and transforms into ammonia, resulting in the formation of these stains.

It is important to note that these yellow spots on pillows do not indicate the presence of mold. They are natural, but it is advisable to remove them early to ensure fresh and aesthetically pleasing pillows.

  • Spray a pre-treatment onto the pillow to remove the stains and leave it for 15 minutes.
  • Use a toothbrush to remove any debris from the pillow.
  • Dissolve a spoonful of OxiClean (or other oxygen bleach) in hot water in a bathtub, sink, or washbasin overnight.
  • The next day, wash and air-dry the pillow as usual.
