Yes, outdoor furniture covers can be washed. Thank goodness, because leaving them dirty is like letting your Garden Furniture wear last year’s muddy festival outfit. The short answer? Most covers can be cleaned safely, but you need to check the material first. Stick around for the best cleaning tips, common mistakes to avoid, and clever ways to keep your covers looking new season after season.

Can Outdoor Furniture Cushion Covers Be Washed? Yes, But Always Check First
Why It's Important to Clean Your Covers Annually
Outdoor covers take the brunt of everything; rain, dust, falling leaves, and even the neighbour’s cat using them as a nap spot. If you leave them grimy, they’ll start smelling musty, growing mould, and breaking down faster. A simple annual wash not only keeps them fresh but also adds years to their life.
The Danger of Damaging the Waterproof or UV-Resistant Coating
Here’s the catch: scrubbing too hard or grabbing any old detergent can ruin the built-in waterproof or UV-resistant finish. Once that’s gone, your cover is basically just fabric in the rain. Cleaning gently means you get the best of both worlds, freshness and protection.
Before You Wash: The Most Important Step
How to Read Care Labels Before Washing Outdoor Furniture Covers
That little tag on the inside seam is your best friend. It tells you if the cover can handle the washing machine, which detergents to use, and the safe temperature. Ignoring it is like cooking without a recipe, you might get lucky, but you might also ruin dinner.
What to Do if There Is No Label on Your Patio Furniture Covers
Lost the care label? Don’t stress. The safest bet is hand washing with mild soap and lukewarm water. Avoid bleach or harsh chemicals, and if you’re not sure, always test a small hidden corner first.
How to Wash Outdoor Furniture Cushion Covers by Hand (Safest Method)
Step 1: Brushing Off Loose Dirt Before Cleaning Outdoor Cushions
Start with the basics, shake off dust, leaves, and dried mud. A soft brush works wonders and saves you from rubbing grit deep into the fabric when washing.
Step 2: Spot-Treating Stains Like Bird Droppings or Mildew on Covers
Bird droppings, tree sap, or mildew patches? Dab them with a mild soap solution and a sponge. To clean mildew from outdoor furniture covers, a simple mix of white vinegar and water can do the trick. Always rinse well afterwards.
Step 3: Washing Outdoor Cushions with Mild Soap and Lukewarm Water
Fill a bucket with lukewarm water and add a little gentle detergent. Work over the cover with a sponge or brush, then rinse until the water runs clear. Never wring the fabric, it stretches fibres and weakens the seams.

Can Outdoor Furniture Covers Be Washed in Washing Machine?
When It’s Safe to Machine Wash Patio Furniture Covers
Not all covers are machine-friendly. Polyester, vinyl-coated fabrics, or synthetic blends usually cope well. But natural cotton canvas? That can shrink or warp if you’re not careful. Always double-check the label before throwing it in.
Washing Garden Furniture Covers on a Gentle, Cool Cycle
If machine washing is safe, stick to a delicate cycle, cool water, and a non-biological detergent. Hot washes are a no-go, they can melt coatings or make fabrics lose shape. Gentle cycles keep your covers clean without punishment.
Why Fabric Softener Should Never Be Used on Outdoor Cushion Covers
It smells lovely, sure, but fabric softener kills water resistance faster than a downpour. Want freshness? Try cleaning outdoor cushions with baking soda or simply let them air-dry in the garden breeze.
How to Dry and Reproof Outdoor Cushion Covers After Washing
Air-Drying Thoroughly to Avoid Mould on Outdoor Cushions
Forget the tumble dryer, heat is a cover’s worst enemy. Instead, hang them in a shaded, breezy spot until they’re bone dry. Even a little leftover dampness is an open invite for mould.
Restoring Waterproofing Protection on Outdoor Furniture Covers
After a good wash, covers often need a top-up of waterproofing. A quick spray-on fabric protector helps restore their defence against rain and UV rays. It’s like giving them an invisible shield before the next storm rolls in.

FAQ: Washing and Cleaning Outdoor Furniture Covers
How Do You Clean Outdoor Cushions Without Removable Covers?
Mix warm water with mild soap and gently scrub the surface with a brush. For stubborn odours, sprinkle baking soda over the cushion before rinsing. Rinse well and dry fully in sunlight.
Can I Use a Pressure Washer on Patio Furniture Covers?
Resist the urge, it’s too aggressive. Pressure washers can strip coatings or even rip seams. A garden hose does the job without the drama.
