Outdoor cushions take a beating in Greece — blazing summer sun, sea salt air, dusty sirocco winds, and the occasional olive-tree stain are all part of the deal. The video above shows the cleaning process in action; this article breaks it into clear, repeatable steps so you can apply the same method to your villa terrace, holiday rental, or hotel pool area. A thorough clean once or twice a season keeps colours vivid, prevents mould from taking hold, and extends the life of your cushions by years.
Why Outdoor Cushions Need Special Care
Most outdoor cushion fabric — Sunbrella, polyester, olefin — is treated to resist fading and moisture, but that treatment wears down over time if dirt and salt are left to sit. In coastal and island settings, airborne salt deposits create a film that traps humidity against the fabric even when cushions feel dry to the touch. Regular cleaning is not just cosmetic: it removes the salt and organic matter that feed mildew spores.
In holiday rentals and hotel settings, neglected cushions are one of the first things guests photograph and mention in reviews. A clean, well-maintained terrace signals that the whole property is cared for — making this a simple, high-ROI maintenance task.
What You Need Before You Start
You need mild dish soap or a purpose-made outdoor fabric cleaner, warm water, a soft-bristle brush (a nail brush or soft scrubbing brush works well), a bucket, and access to a hose. For mould or mildew patches, a diluted solution of white vinegar (1 part vinegar to 4 parts water) or a very diluted bleach mix (1 tablespoon of bleach per litre of water, only for colourfast, non-Sunbrella fabric) will be needed. Avoid pressure washers on full power — the jet can break down stitching and force water deep into foam cores where it stays for days.
5 Steps to Clean Outdoor Cushions
- 1
Brush off dry debris first
Take the cushions off the furniture and stand them on their edge. Using a dry soft-bristle brush, sweep away loose dust, dried leaves, sand, and any surface dirt. Doing this dry prevents debris from turning into muddy streaks once water is introduced. Pay attention to piping seams and zipped edges where grit accumulates.
- 2
Mix your cleaning solution and pre-soak
Fill a bucket with warm water and add a few drops of mild dish soap, or measure out your fabric cleaner according to the label. Lay the cushion flat on a clean paved surface and pour or spray the solution generously over the fabric. Let it sit for 10 to 15 minutes — this loosens embedded dirt, pollen, and salt deposits before you scrub.
- 3
Scrub gently in circular motions
Using your soft-bristle brush, work the soapy water into the fabric with gentle circular strokes. Focus extra attention on any stained patches, mould spots, or discoloured seams. For mould, apply your vinegar solution directly to the affected area, let it sit for five minutes, then scrub. Avoid scrubbing so hard that you raise the fabric pile or damage the weave.
- 4
Rinse thoroughly with clean water
Use a hose on a gentle setting to rinse all soap and cleaner out of the cushion. Start from the top and work downward so you push residue off rather than back into the fabric. Squeeze the cushion lightly along its edges to help expel soapy water from the foam core. Incomplete rinsing leaves a detergent residue that actually attracts new dirt faster.
- 5
Dry completely before storing or replacing
Stand the cushions on their edge or prop them against a wall in a well-ventilated, shaded spot. Direct harsh midday sun can fade fabric — morning or late-afternoon sun is ideal. Allow at least four to six hours of drying time, or longer for thick cushions; the foam core holds moisture longer than the fabric surface suggests. Do not zip covers closed or stack cushions until they are fully dry — trapped moisture is the primary cause of mildew.

FAQ
- Can I put outdoor cushion covers in the washing machine?
- Many outdoor cushion covers with removable zips can be machine-washed on a gentle cold cycle, but always check the care label first. Sunbrella and most branded performance fabrics are machine-washable without bleach. Avoid hot cycles, which can shrink or warp covers, and always air-dry rather than tumble-drying.
- How do I get rid of black mould spots that won't scrub off?
- For stubborn mould on colourfast fabric, mix one tablespoon of white vinegar with one litre of warm water, apply directly to the spots, and leave for 15 to 20 minutes before scrubbing. On light-coloured or non-Sunbrella fabric you can try a very diluted bleach solution (1 tablespoon per litre), but test a hidden area first. If mould has penetrated deep into the foam core, the insert may need replacing.
- How often should outdoor cushions be cleaned in Greece?
- For a private home used seasonally, a thorough clean at the start of summer and again at the end — before storage — is usually sufficient, with a quick hose-down after dusty or windy weather. Holiday rentals and hotel properties benefit from a light clean between guest turnovers and a deep clean monthly during peak season (June to September), when salt, sunscreen, and heavy use accelerate soiling.
