Memory foam is a viscoelastic polyurethane foam that is a very soft, moldable material used chiefly for all bedding accessories- mattress, pillow, topper, etc. It offers exceptional cushioning and is highly responsive.
Memory foam conforms to the body and acts effectively in pressure relief. Naturally, you may be owning one or more products made out of memory foam as it is a popular choice as a bedding staple.
However, over time, you may have noticed the discoloration of memory foam in your product – from white to yellow. It may raise the alarm in your mind.
Does it mean the product has gone wrong or something? Should I do away with the product? How to get yellow stains removed from my beddings? Etc.
Need an answer to the questions mentioned above? You are at the right place. Read on.
Why Does Memory Foam Turn Yellow?
While it’s natural for many of you to have these worries, but relax. Firstly, you don’t need to be alarmed, as slight discoloration of memory foam is natural and something that’s part of memory foam’s aging process. It is not harmful and toxic in any way.
Several factors contribute to the change in color in memory foam. A memory foam turns yellow mainly due to oxidation. Factors such as exposure to UV light, pollution, emissions, etc., are responsible for expediting the oxidation process of all foam.
Further high temperatures also lead to oxidation in the basic components of memory foam. One more reason for the discoloration can be attributed to the presence and use of flames retardant chemicals during the construction of products made out of memory foam.
Some other reasons for the appearance of yellow stains on memory foam products include food or drink spillage, sweating and body oil, vomit or urination by a child, pet dander, molds/ mildew, dead skin, dust mites, etc. Most of such causes may leave a lingering smell.
Usually, the changed color of memory foam is permanent, and the whole process of oxidation takes time. Although this natural process can’t be withdrawn, it is possible to slow it down.
Again, some DIY tricks can also help us to get the yellow stains out of the foam if the cause is other than oxidation.

Important Tips to Prevent Memory Foam Turning Yellow
We have already discussed how to remove yellow stains from memory foam beddings. However, it is always better to prevent the problem than its occurrence.
We can slow down the natural process of yellowing your memory foam mattress and prevent other causes that lead to discoloration.
Some ways can prevent your memory foam products from turning yellow
1. Using waterproof Mattress Protector
Buying and using a mattress protector on any mattress is the best way to extend its life. A waterproof mattress protector saves the mattress from those occasional spillages, peeing, and others.
Otherwise, you can use a large waterproof fitted bedsheet. It will help you cover the whole bed easily. Using such waterproof and washable covers & protectors prevent your memory foam mattress or topper from getting wet.
2. Evade direct exposure to sunlight
Ensure that the memory foam is exposed to direct sunlight. If you have to dry/air the mattress or pillow or topper, keep it outside under a shade and not more for 5-6 hours—direct exposure with quicken the oxidation process.
Also, exposure to light will compromise the lifespan of memory foam as it may damage the internal structure of the material.
3. Regular cleaning of Your Memory Foam
Improper cleaning of memory foam products can cause yellow stains on foam. Body Oil, sweat, dead skin, and mold can develop in these circumstances.
At times the spots will get strong if left untreated. Avoid eating on your mattress. Eating on the bed will lead to dropping food and cause yellow stains.
4. Opt for certified memory foam products
While buying a memory foam product, especially mattresses, it is recommended to check the certification. Buying a CertiPUR-US ensures its premium quality.
A certified Memory Foam has to undergo severe testing and is non-toxic. They are free from any harmful flame retardants. In such a case, the performance of the foam product will remain as is, even in the middle of noticing discoloration.
Cleaning memory foam can be challenging without the proper information. Following instructions/ rules of cleaning and maintain memory foam bedding is thus very important.
Proper upkeep of memory foam beddings enhances its performance and its durability. It is advised to read the care instruction provided by the brand for care and maintenance of the products. It saves you from the risk of unknowingly ruining your memory foam.
Most of the items required to clean the foam and remove yellow stains are conveniently found either in your house or online. What is crucial is not to neglect the lightest stains; otherwise, the spots can become permanent.
