How to Clean Outdoor Cushions – The Easy Way

Outdoor cushions go through a lot—sun, rain, dirt, and the occasional BBQ sauce spill. But here’s the good news: cleaning them doesn’t have to be a headache. With the right approach, you can keep them looking fresh without spending hours scrubbing.

In this guide, we’ll walk you through the simplest, most effective ways to clean outdoor cushions, whether they’re made of Sunbrella fabric, polyester, or have non-removable covers. No fancy tools or expensive cleaners needed—just practical tips that actually work.

How to Clean Outdoor Cushions

Cleaning outdoor cushions isn’t complicated, but the method depends on the material and how dirty they are. Here’s the easiest way to do it:

1. Check the care label – Some fabrics need special treatment.
2. Remove loose dirt – Shake or vacuum before washing.
3. Spot clean stains – Mild soap and water work wonders.
4. Deep clean if needed – A soft brush helps lift grime.
5. Rinse & dry completely – Prevents mildew and odors.

Now, let’s break it down step by step.

Pre-Cleaning Prep: Get Rid of Dirt & Debris

Before diving into a deep clean, start by removing loose dirt and debris. This makes the actual cleaning much easier.

• Shake them out – A quick shake removes dust, leaves, and crumbs.
• Vacuum with a brush attachment – Great for textured fabrics that trap dirt.
• Lightly brush – A soft-bristle brush helps loosen stuck-on grime.

This step only takes a few minutes but makes a big difference in the final result.

Spot Cleaning Stains (Before a Full Wash)

Spills happen—whether it’s coffee, grease, or pollen stains. The key is to treat them quickly before they set.

• Mix mild soap (like Dawn) with warm water – Harsh cleaners can damage fabric.
• Blot, don’t rub – Scrubbing can spread the stain.
• Rinse with clean water – Soap residue attracts more dirt.

Pro Tip: For mildew or stubborn stains, a mix of vinegar and water (1:1 ratio) works as a natural disinfectant.

3. Deep Cleaning Methods (Based on Cushion Type)

A. Machine-Washable Cushion Covers

If your cushion covers zip off, cleaning is a breeze.

• Use cold water & gentle cycle – Hot water can shrink fabric.
• Skip the bleach – It weakens fibers over time.
• Air dry only – High heat can warp or fade the material.

This method keeps covers looking new without much effort.

B. Non-Removable Cushions (Hand Wash Only)

For cushions that can’t go in the washer, a simple hand wash does the trick.

• Fill a tub with warm, soapy water – Mild detergent is best.
• Scrub gently with a soft brush – Focus on stained areas.
• Rinse thoroughly – Leftover soap can attract dirt.

Let them dry in the sun—UV rays help kill bacteria naturally.

C. Heavy-Duty Cleaning for Mold & Mildew

Musty-smelling cushions? This mix works like magic.

• 1 cup vinegar + 1 cup water + a few drops of tea tree oil (natural antifungal).
• Spray and let sit for 15 minutes – Then rinse well.

This not only cleans but also helps prevent future mildew growth.

Drying Tips to Prevent Mold & Damage

The worst mistake? Storing cushions while they’re still damp.

• Always air dry – Never use a dryer (it can warp the fabric).
• Flip them occasionally – Ensures even drying.
• Store only when bone-dry – Prevents musty smells.

A sunny day is perfect for quick drying and disinfecting.

How to Maintain Outdoor Cushions (So They Stay Clean Longer)

A little upkeep goes a long way in keeping cushions fresh.

• Store them when not in use – A deck box or waterproof cover helps.
• Brush off dirt weekly – Prevents deep-set stains.
• Use fabric protectors – Sprays like Scotchgard add a water-resistant barrier.

With these habits, you’ll rarely need a deep clean.
