Among natural remedies, lemon is one of the most effective for removing yellow stains. In addition to being environmentally friendly, it has strong bleaching properties.
Mix the juice of three lemons with one cup of warm water. With a sponge soaked in the solution, scrub the stains, then dry with a clean cloth. Finally, let the mattress air dry or use a hair dryer to dry faster.

Laundry detergent for stubborn stains

For particularly stubborn stains, washing powder is a reliable helper. Prepare a solution of hot water and washing powder (follow the dosage instructions on the packaging). Use a cloth dipped in the solution to clean the stains, then use another cloth dampened with clean water to remove any detergent residue. Allow the pillow or mattress to air dry.

Hydrogen peroxide + baking soda

Hydrogen peroxide has strong bleaching properties. Combined with baking soda, which has a disinfecting effect, this method is extremely effective for yellowed pillows and mattresses.
Mix 4 tablespoons of baking soda with 500 ml of peroxide. Pour the solution into a spray bottle and spray the affected areas. Then sprinkle generously with baking soda and leave to act for at least 6 hours. After drying, vacuum up the residue.

How to prevent yellow spots

A yellowed mattress or pillow usually means that the material is not “breathing” well. To maintain a fresh look and prevent stains, it is advisable to air out your mattress twice a year. Exposing it to direct sunlight helps kill dust mites, a major allergen.

Also, for good health, ventilate your bedroom for at least 15 minutes a day. This will freshen the air and help your bedding stay cleaner.

To reduce excessive sweating while sleeping and thus avoid stains, choose breathable fabrics. The best choices for sheets, pillowcases and mattress protectors are cotton, linen and bamboo.
