People can remove the yellow stains from their pillow using an item costing as little as 4p from Asda.
While it's recommended that households should be washing their pillows a minimum of twice a year, cleaning yellow stains from a pillow can be difficult. These stains are caused by sweat.
But the more someone sweats, the more that moisture seeps through the pillowcase and onto their pillow, causing the stains. People with oily hair or those that go to bed with wet or damp hair may also discover yellow stains on their pillow.
