Outdoor furniture has to put up with a lot—rain, heat, salt air, dust, bird droppings, and the occasional spilled drink. The good news is that with a simple routine, your cushions can stay cleaner, fresher, and more comfortable for longer.
This outdoor furniture cushions care guide covers how to clean, protect, and refresh outdoor cushions, plus how to prevent mould, fading, and waterlogging—without overcomplicating things.
If you're setting up or upgrading an outdoor space, it’s worth understanding how different materials perform long-term. Our complete guide to outdoor bean bags in Australia explains UV resistance, waterproof ratings, and what to look for in durable outdoor fabrics.
What outdoor cushions are made from
Outdoor cushions come in a range of fabrics, and your cleaning method should match the material. Common cushion covers include acrylic, PU-coated polyester, cotton canvas, and olefin. Each one handles water, UV, and cleaning chemicals differently, so always check the care label first.
If you're choosing new cushions or covers for an exposed patio, it's worth prioritising fabrics designed for outdoor performance. Olefin is popular for outdoor use because it holds colour well and resists moisture. Learn more in what olefin fabric is.
If your outdoor space is fully exposed, it helps to understand how different fabrics cope with sun, moisture, and long-term wear. This guide to outdoor seating materials for Australian conditions breaks down what to prioritise.
Prevent damage before it starts
Most cushion problems come from three things: too much sun, repeated soaking, and slow drying. Fix those and you’ll dramatically extend cushion life.
Sun protection
UV exposure fades fabric and can weaken stitching over time. If your setup is in full sun, rotate cushions occasionally so one side doesn’t take all the exposure. When cushions aren’t in use, move them to shade, or store them indoors.
If your outdoor area is permanently exposed, consider a fabric protector that’s compatible with your cushion fabric and follow label directions.
Rain and snow protection
Water-resistant is not the same as waterproof. Even outdoor-rated cushions can absorb moisture if they’re repeatedly saturated or stored while damp.
- Bring cushions inside during prolonged wet weather.
- If they get soaked, stand them upright to drain, then air dry completely.
- Avoid stacking damp cushions—this traps moisture and encourages mildew.
Stop mould and mildew early
Mildew needs moisture plus grime. Keeping cushions clean and dry is your best prevention. If you do see mildew, treat it promptly. Use this guide: how to remove mould from fabric.
Some outdoor fabrics use antimicrobial treatments to slow mould and bacteria growth, but they don’t replace drying and cleaning habits. If you’re curious about how those treatments work, read what antimicrobial treatment is.
How to clean outdoor cushion covers and inserts
Before deep cleaning, remove loose debris. This prevents dirt from turning into muddy paste when you add water.
Step 1: Remove surface debris
Use a soft brush or a vacuum with an upholstery attachment to lift dirt, sand, and crumbs. Pay attention to seams and piping where grit collects.
Step 2: Spot clean first
For spills, blot (don’t rub) with a damp cloth. Then use mild soap and water. Rinse with clean water and blot dry. Treating spots early reduces the chance of permanent staining.
For greasy food stains, use a targeted approach based on fabric type. This article helps: how to remove oil stains.
Step 3: Wash the cushion cover
If your cushions have removable covers, check the care label. Many outdoor covers can be machine washed on a gentle cycle with cool water and mild detergent. Avoid bleach unless the label explicitly allows it.
If your cushions don’t have removable covers, scrub using mild soap and warm water with a soft sponge. Let the solution sit for a few minutes on stubborn patches, then rinse thoroughly.
Step 4: Dry thoroughly
Drying fully matters more than you think. Most outdoor cushion odour issues are a drying problem, not a cleaning problem.
- Press with towels to remove excess moisture.
- Air dry in a well-ventilated area.
- Stand cushions on edge so air reaches both sides.
- Do not store until completely dry.
Refreshing water repellency
Over time, coatings wear down. A quick test: sprinkle water on the fabric. If it beads up, you’re good. If it soaks in quickly, it may be time to refresh the protective coating with a fabric-safe water repellant spray.
Choose a product appropriate for your fabric and follow the manufacturer’s directions carefully.
Quick care for cushion frames and nearby furniture
Cushions often sit on frames made of metal, wood, or plastic. Keeping those clean helps cushions stay cleaner too.
Metal frames
Wash with mild soap and water. If you notice rust spots, gently remove them with fine-grit sandpaper, then touch up protective paint if needed.
Wood frames
Wipe down with mild soapy water and a soft cloth. Avoid pressure washers, which can gouge wood. Keep timber as dry as possible and re-oil periodically if recommended for your finish.
Plastic frames
Wipe with gentle soap and water. For white plastic, a mild abrasive cleaner can help lift stubborn marks, but spot-test first to avoid dulling the surface.
Storage tips that prevent cushion damage
Smart storage is one of the easiest ways to extend cushion life—especially in humid conditions.
- Store cushions in a dry, ventilated area (garage, shed, indoor cupboard).
- If using storage bags, ensure there’s airflow (vent holes or breathable material).
- Avoid sealing damp cushions in plastic.
- Clean and fully dry cushions before long-term storage.

When to DIY vs when to replace
Most cushion issues are fixable with proper cleaning and drying. Consider replacement when:
- The insert no longer rebounds (permanent flattening).
- Mould has penetrated deep into foam and odour won’t lift after cleaning.
- Stitching has deteriorated and the cover is failing.
Kick back and enjoy your outdoor space
A little routine maintenance goes a long way—brush off debris, treat spills quickly, dry thoroughly after washing, and store cushions out of harsh weather when you can. Do that, and your outdoor seating stays comfortable, fresh, and ready whenever the sun’s out.
