Pillowcases and pillow cores come into contact with dirt and grime daily, and over time, they may start to show signs of yellowing. It’s important to address this issue to prevent skin and respiratory problems.

How to Clean Yellowed Pillow Cores

During sleep, sweat, excess oil, and cosmetics can seep directly into the pillow core through the case. Additionally, dust and dead skin cells can accumulate, causing the core to become musty and discolored over time.

To clean yellowed pillow cores, try the following methods:

Use Baking Soda and White Vinegar

These common household ingredients are effective in removing yellow stains and neutralizing odors.

Mix 1/2 cup of baking soda with 1/2 cup of white vinegar in a warm water basin and stir well.

Soak the pillow cores in the mixture for 30-60 minutes.

Gently scrub the stained areas with a soft brush.

Rinse the cores with clean water and dry them in the sun.

Use Detergent and Warm Water

This convenient method uses readily available laundry detergent.

Mix detergent into a basin of warm water (approximately 40°C).

Soak the pillow cores for 30-40 minutes to loosen the stains.

Hand-wash or machine-wash the cores on a gentle cycle.

If hand-washing, rinse with water after cleaning and dry in the sun.

Use Lemon and Salt

This natural, chemical-free method is ideal for those with sensitivities to cleaning agents. However, it is best suited for lightly stained or faintly yellowed pillow cores.

Mix lemon juice and salt to form a thick paste.

Apply the paste to the stained areas of the pillow core.

Let it sit for about 20 minutes, then wash with warm water and dry.

Use a Steam Washer

This modern approach effectively kills bacteria and deep-cleans without the use of chemicals.

Place the pillow cores in a steam washer.

Select the appropriate setting for cleaning pillows.

Dry the cores after the cycle is complete.

Notes on Cleaning Pillow Cores

To ensure optimal cleaning and maintain the shape of your pillow cores, keep the following in mind:

Read the Care Label: Some pillow cores, especially memory foam ones, may not be suitable for soaking or machine washing.

Avoid High Temperatures: Excessive heat can deform the core or affect the fabric’s quality.

Ensure Complete Drying: Incompletely dried cores can develop odors and bacteria. Sun-drying or machine-drying is recommended.

Regular Cleaning: Wash pillow cores at least once every 2-3 months to maintain hygiene and prolong their lifespan.

Replace When Necessary: If your pillow core becomes lumpy, develops an odor, or is difficult to clean, consider replacing it for a better night’s sleep and improved health.
