Before taking such measures, instead, focus on inexpensive cleaning tips to make them look their best. Here are some methods to implement once a month to treat them effectively. This also applies to cushions and pillows.
What causes yellow pillows?
As you can imagine, the main and most frequent reason is still perspiration. And for good reason: your pillow will gradually and irreversibly turn yellow every night because of this. Body sweat penetrates the pillow’s fibers before appearing on the surface. But while perspiration remains the most common cause, other factors, such as saliva, also come into play.

The fluids we secrete contribute to the yellowing of the pillow that absorbs them. Furthermore, this discoloration isn’t just an aesthetic concern, as it’s evidence that bacteria and dust mites have taken up residence deep within the fibers. This is natural, since these creatures thrive in damp environments, which can lead to conditions like asthma, allergies, or rhinitis.
