Memory foam turns yellow because it is just a natural part of memory foam's ageing process and it is nothing to be concerned over. The colouration is caused by the oxidation of the material and it is not toxic or harmful in any way.It is simply a sign of entropy, of the inexorable path of time.
Yellowing is a very common sign of normal oxidation with current memory foam. Nothing to be alarmed about!
Pre-treating your mattress with a sprinkling of baking soda can refresh its surface. Applying a cleaning solution with hydrogen peroxide, water, and soap along with another round of baking soda can help get rid of yellow stains. Products designed for upholstery cleaning may eliminate or reduce yellow discoloration.
Polyurethane foams will discolor if oxidized. Oxides of nitrogen from tow motor emissions, gas fired furnaces or pollution can cause a foam to oxidize and become yellow. This phenomenon may be more observable in the winter when warehouses are closed up and gas furnaces are in operation.
Using harsh chemicals such as bleach will damage the foam materials. Instead, use a homemade solution of 1 part mild detergent and 2 parts water shaken in a spray bottle until dissolved. Lightly spray the mixture on the mattress. You only need enough to make the fabric surface lather slightly.
Sun Exposure: Sunlight is a natural revitalizer for memory foam. Place your topper in direct sunlight for a few hours. The sun will help to evaporate any moisture trapped in the foam, which can be a cause of lumpiness.
While we always advise against using hydrogen peroxide because it can affect the color and integrity of your memory foam mattress or mattress cover, sometimes a stronger solution is needed to get tough stains out.
Mix 1 part white vinegar and 1 part water and spray the area generously. Sprinkle some baking soda on top and leave it to sit overnight or for at least eight hours. Once it's dry, vacuum the residue and check the stain. If it's still visible, repeat the process until you're satisfied with the result.
Mattresses can turn yellow due to natural processes such as sweat from the human body, skin rashes and friction from clothes. Such stains accumulate over time and form noticeable yellow stains on the surface of the mattress. Sweating in particular is the main cause of yellow stains on the mattress.
White clothes can turn yellow due to a variety of factors, such as using too much detergent and fabric softener, oxygenation, deodorant stains, washing with well water or long-term storage.
You can make your own natural memory foam mattress cleaner by mixing 1 part water with 1 part white vinegar or you can purchase a natural memory foam mattress cleaner. Always spot test your cleaner on a small area of the mattress first to ensure it won't damage the foam.
The optimal option is acetone or even nail polish remover.
Quality sleep is essential for our overall health, and a good mattress plays a crucial role in ensuring a good night's sleep. Experts recommend replacing your mattress every 6 to 8 years, but there are factors can influence this timeframe.
Hydrogen Peroxide and Dish Soap: Mix a solution of 1 part hydrogen peroxide and 1 part dish soap. Lightly dampen a clean cloth or sponge with the solution and gently blot the stained area. Rinse the area with a damp cloth to remove any residue, and allow it to dry completely.
It can be easy to think you have dirty pillows or mattresses when you see yellow stains but the most common reason for yellow stains on mattresses and pillows is often sweat and sebum. The average adult can lose between 500-700ml of sweat per night, and if you're a hot sleeper that could be even more.
containing polyurethane may cause yellow discoloration of the entire foam block. This is because the polyurethane material itself has a property of turning yellow, depending on UV irradiation, temperature, and humidity. You can rest assured that being yellowing is a natural phenomenon.
Natural Oxidation
Yellow stains from oxidation don't have a smell and persist despite regular cleaning. Oxidation is natural and will eventually happen to any mattress, especially memory foam ones. However, you can slow oxidation down by keeping your mattress away from moisture and out of direct sunlight.
Without a mattress protector in place, yellow stains caused by sweat, body oils, urine, dust, dirt and other debris will begin to build up. Hydrogen peroxide is a powerful cleaning solution that helps shift stubborn stains in minutes. However, if you don't use it properly, you could cause lasting damage to your bed.
Memory foam turns yellow because it is just a natural part of memory foam's ageing process and it is nothing to be concerned over. The colouration is caused by the oxidation of the material and it is not toxic or harmful in any way.It is simply a sign of entropy, of the inexorable path of time.
The reason for the colour change is oxidation of the surface of the memory foam mattress as it reacts with oxygen in the air. This is like metals tarnishing, or vegetables discolouring when cut and left in the air too long.
Clean stains with laundry detergent and water
Some manufacturers suggest using water mixed with gentle laundry detergent or dish soap, but check the manufacturers' care instructions first. This is because harsh chemicals can break down the memory foam inside.
Mix one part baking soda and two parts cool water to form a paste. With a cool, damp cloth, apply the paste to the stained area of the mattress and lightly dab, working the paste into the stain. Let the paste dry for 30 minutes. Repeat the process with a cool, damp cloth.
Memory foam mattresses are an investment that can last for years with proper care. People should clean stains when they occur to prevent them from becoming permanent. Cleaning a mattress is possible using everyday household ingredients, such as white vinegar, baking soda, and dishwashing soap.
