Outdoor cushions are a fantastic way to add comfort, style, and personality to your garden or patio furniture. But exposure to the elements rain, pollen, bird droppings, food stains, and UV rays can quickly make even the best cushions look worn out. Fortunately, with the right care and a consistent cleaning routine, you can keep your outdoor cushions looking fresh, vibrant, and long-lasting.
Here we walk you through the best way to clean outdoor cushions, remove common stains, and share tips for maintaining their appearance year after year.
Why Cleaning Outdoor Cushions Matters
Outdoor cushions are an investment in your comfort and outdoor aesthetic. Dirty or mouldy cushions look unappealing and can harbour allergens, bacteria, and mildew. Regular cleaning:
- Extends the life of your cushions
- Maintains colour and fabric integrity
- Prevents unpleasant odours
- Keeps your outdoor space guest-ready
What You’ll Need to Clean Outdoor Cushions
Before you start, gather the following supplies:
- Mild detergent or dish soap
- Warm water
- White vinegar (for mould/mildew)
- Soft-bristled brush or sponge
- Garden hose or spray bottle
- Bucket
- Microfibre cloths or towels
- Optional: Fabric protector spray (e.g., Scotchgard)

Step-by-Step: How to Clean Outdoor Cushions
1. Check the Manufacturer’s Care Label
Before cleaning, always read the care label or manufacturer instructions. Some outdoor cushions come with removable, machine-washable covers, while others require spot cleaning.
If you’re buying new cushions, consider custom options with washable covers like the ones offered at The Cushion Guys—for easier maintenance.
2. Brush Off Loose Dirt & Debris
Use a soft-bristled brush to remove dirt, leaves, pollen, and debris from the cushion surface. Don’t forget the seams and corners, where debris tends to accumulate.
3. Mix a Cleaning Solution
In a bucket, mix:
- 1 tablespoon of mild detergent
- 1 litre of warm water
For tougher stains or mildew:
- Add ½ cup of white vinegar to the solution.
Avoid using harsh bleach or chemicals, especially on dyed or patterned fabrics they can fade colours and weaken fibres.
4. Spot Clean or Scrub the Entire Cushion
Dip a sponge or brush into the cleaning solution and gently scrub the cushion. Focus on stained or dirty areas, but it’s usually best to clean the entire surface to avoid watermarks.
Let the solution sit for 5–10 minutes to break down grime, but don’t let it dry out.
5. Rinse Thoroughly
Use a garden hose on a low-pressure setting to rinse the cushions. Be sure to remove all soap residue leftover soap can attract more dirt.
If your cushions have removable covers, you can machine wash them on a gentle cycle using cold water and mild detergent.
6. Blot Excess Moisture & Dry Completely
After rinsing, press a clean towel or microfibre cloth against the cushion to absorb excess moisture. Then, let the cushions air-dry completely in a sunny, well-ventilated area.
Avoid direct sunlight for prolonged periods this can cause fading. Never use a tumble dryer unless the care label says it’s safe.

How to Remove Specific Stains
Here are tips for common outdoor cushion stains:
- Mould or Mildew: Scrub with a mixture of 1 part white vinegar to 3 parts water. Let it sit for 10 minutes before rinsing.
- Bird Droppings: Let it dry, scrape off the excess, then blot the area with soapy water.
- Food & Grease Stains: Use a dish soap solution and dab gently with a cloth.
- Tree Sap: Dab with rubbing alcohol, then rinse thoroughly. Test a hidden area first.
Ongoing Maintenance Tips
Once your cushions are clean, keep them looking new with these care habits:
1. Store Cushions When Not in Use
Invest in storage boxes, a shed, or weatherproof cushion bags to protect your cushions during heavy rain or throughout the winter months in the UK.
2. Use Waterproof Covers
High-quality outdoor cushion covers are your first defence against water, UV rays, and dirt. Some, like those from The Cushion Guys, are made with durable water- and UV-resistant fabrics ideal for year-round use.
3. Apply Fabric Protector
After cleaning and drying, consider spraying cushions with a fabric protector like Scotchgard. This helps repel stains and makes future cleaning easier.
4. Rotate & Flip Cushions
To prevent uneven fading or wear, rotate and flip your cushions regularly especially if only one side gets sun exposure.
When to Replace Outdoor Cushions
Even with proper care, there comes a time when cleaning isn’t enough. Signs you may need to replace your outdoor cushions include:
