Drying Tips

Proper drying is essential to prevent mold and mildew.

• Dry in direct sunlight if possible.
• Turn the mattress or pillow occasionally while drying.
• Use fans to speed drying indoors.
• Make sure the item is completely dry before covering or using it.

Stains That May Not Come Out

Yellowing caused by:

• Years of oxidation
• Very old sweat stains
• Foam degradation
• Mold damage

may lighten but not disappear completely.

Prevention

• Use a waterproof mattress protector.
• Use pillow protectors under pillowcases.
• Wash bedding weekly.
• Sprinkle baking soda on the mattress every 2–3 months, let it sit for several hours, then vacuum it off.
• Air out mattresses and pillows regularly to reduce moisture buildup.

If your mattress or pillow has black, green, or fuzzy spots, that may indicate mold rather than ordinary yellowing. In that case, cleaning may not be sufficient, and replacement is often the safer option, especially if the mold has penetrated deep into the material.
