Why Does Mould Grow on Outdoor Cushions?

Mould thrives in damp, warm environments, making outdoor cushions the perfect breeding ground. Common causes of mould growth on cushions include:

  • Poor air circulation

  • Storage in damp or dark areas

  • Spills and organic matter left uncleaned

Preventing mould growth is key to maintaining the longevity of your outdoor cushions. Let’s dive into how to clean mould off outdoor cushions and keep them in top shape.

Step-by-Step Guide: How to Clean Mould Off Outdoor Cushions

Step 1: Brush Off Loose Mould

Take your cushions outdoors and use a soft-bristled brush to remove any visible mould spores. Brushing should be done gently to avoid spreading spores in the air.

Step 2: Apply a Cleaning Solution

  • Vinegar Method: Mix equal parts white vinegar and water in a spray bottle. Spray the solution generously over the affected areas and let it sit for 15-20 minutes.

  • Detergent Method: Mix mild detergent with warm water and scrub the mouldy spots with a soft brush.

  • Baking Soda Boost: For tough stains, sprinkle baking soda over the cushions before applying vinegar.

Step 3: Scrub and Rinse

Using a brush or sponge, gently scrub the moulded areas to lift the stains. Rinse the cushions thoroughly with a hose or a bucket of clean water to remove all residue.

Step 4: Dry in Sunlight

Sunlight is a natural mould killer. Place the cushions in direct sunlight and allow them to dry completely. Ensure they are fully dry before using or storing them to prevent future mould growth.

Step 5: Prevent Future Mould Growth

  • Store cushions in a dry, well-ventilated area.

  • Use waterproof covers to protect against moisture.

  • Clean spills immediately and dry cushions promptly.

  • Air out cushions regularly to prevent dampness.
