The Sissonne Guide: How to Wash & Care for Outdoor Cushion Covers

The Sissonne Guide: How to Wash & Care for Outdoor Cushion Covers

A luxurious outdoor space is defined by its comfort. Staple pieces like sofas and dining chairs are transformed by plush, high-quality cushions that invite you to sit and stay a while. But because they live outside, even the most durable fabrics require periodic care to stay fresh, hygienic, and vibrant.

While our custom-fit protective covers are your first line of defense against the elements, we know that life happens. Whether it’s a splash of red wine during a dinner party or the aftermath of a stormy week, sometimes a deep clean is necessary.

Here is the expert guide to maintaining the pristine look of your Sissonne Outdoor cushion covers.

Why Outdoor Fabrics Need Special Care

Outdoor cushions face a unique set of challenges that your indoor furniture never sees. Understanding these enemies is the first step to defeating them.

1. The Sun vs. The Fabric

Have you ever seen a rust-colored cushion turn pink, or navy blue fade to purple? That is the result of UV degradation on "garment-dyed" fabrics (where color is painted onto the surface).

  • The Sissonne Difference: We exclusively use solution-dyed acrylics, The color isn't just a coating; it is integrated into the liquid fibre before it is even spun into yarn. 

2. The Stain Spectrum

  • Organic Stains: Bird droppings and pollen are acidic and can eat away at fabrics if left to sit.

  • Oily Stains: Sunscreen and body lotions can leave invisible residues that attract dirt over time.

  • The Party Aftermath: Red wine, salad dressing, and chocolate are inevitable guests at any good gathering.

3. Moisture and Mildew

While Sissonne fabrics are water-repellent, dirt trapped in the weave can hold moisture, which breeds mildew. Keeping the fabric clean prevents mould from finding a home.

The Cleaning Toolkit: What You Need

You don't need a chemistry set to clean your cushions. Most issues can be solved with simple household items or specialized performance cleaners.

The Essentials

  • Mild Dish Soap: Gentle and effective for 90% of cleaning jobs.

  • Soft-Bristle Brush: Essential for agitating the fabric without damaging the weave.

The Natural Alternatives

  • White Vinegar: Great for killing mildew spores.

  • Baking Soda: A powerhouse for neutralizing odors and lifting deep-set stains.

  • Borax: An eco-friendly mineral that boosts cleaning power against stubborn grime.

3 Proven Methods to Clean Your Cushions

Method 1: The Hand Wash (Recommended for Routine Cleaning)

This is the safest way to refresh your covers without removing them from the foam core.

  1. Brush Off: Remove loose dirt and debris with a soft brush.

  2. Mix Solution: Combine 1/4 cup of mild dish soap with a gallon of lukewarm water.

  3. Scrub: Use a soft-bristle brush to work the solution into the fabric.

  4. Soak: Let the soapy mixture sit on the fabric for 15 minutes to break down grime.

  5. Rinse: Rinse thoroughly with a hose until the water runs clear. Do not skip this step! Residual soap attracts more dirt.

  6. Air Dry: Stand the cushions on their edge to dry completely.

Method 2: Machine Washing (For Deep Cleans)

Most Sissonne Outdoor cushion covers are removable and machine washable.

  1. Remove & Close: Take the covers off the foam cores and zip them back up. This prevents the zipper from snagging or breaking in the drum.

  2. Wash: Use a delicate cycle with cold water and a mild, color-safe detergent.

  3. No Softeners: Never use fabric softener; it coats the fibers and ruins the water-repellent finish.

  4. Air Dry Only: Never put outdoor covers in the dryer. The heat can shrink them, making it impossible to get them back on the foam.

Method 3: Spot Cleaning (For "Opps" Moments)

Spilled a drop of wine? Act fast.

  1. Blot: Use a clean, dry cloth to blot (don't rub!) the liquid.

  2. Spray: Apply a cleaning solution (soap/water) to the spot.

  3. Agitate: Use a soft sponge or brush to gently work the cleaner into the stain.

  4. Rinse & Dry: Rinse the spot with water and air dry.

The Golden Rule of Drying

Proper drying is just as important as washing.

  • Air Dry Only: We cannot repeat this enough. Heat destroys the specialized coatings on outdoor fabrics.

  • The "V" Shape: When drying cushions, stand them up on their side (like a V). This allows water to drain out of the zipper end and lets air circulate around the entire cushion, speeding up the drying process.

  • No Direct Sun: While drying, keep covers out of direct, scorching sunlight to prevent uneven drying or water spots.
