Understanding Mildew on Outdoor Cushions

Mildew is a type of fungus that thrives in warm, damp conditions, often forming on outdoor cushions that are exposed to the elements. It presents as a thin, dusty layer of grey or white spots and can sometimes turn black or pink.

Causes:

• Humidity: High levels of moisture in the air can encourage mildew growth.
• Lack of Air Circulation: Cushions piled together or stored without proper ventilation may develop mildew.
• Organic Material: Spores feed on organic material on cushions, like pollen or spilled food.

Prevention:

• Proper Storage: Keep cushions dry and store them in well-ventilated areas during off-seasons.
• Regular Cleaning: Wipe down cushions with a mild soap and water solution routinely.
• Protective Covers: Use water-resistant covers to minimize exposure to moisture.

Adapting these practices can help curb the growth of mildew on your outdoor cushions.

Safety Precautions Before Cleaning

Before you begin the process of removing mildew from your outdoor cushions, it's essential to take some safety precautions:

• Wear Protective Gear: Protect your skin and lungs.

  • Gloves: To prevent skin irritation from cleaning agents.
  • Mask: To avoid inhaling mildew spores and cleaning fumes.
