How to Clean Sunbrella Fabric: A Complete Guide for Long-Lasting Beauty

I’m Jessica, a home and garden blogger with over a decade of experience turning backyards into cozy retreats. I’ve decked out my own patio with Sunbrella cushions for years through scorching summers, rainy springs, and even the occasional backyard barbecue disaster. Let me tell you, this fabric is a game-changer for anyone who loves al fresco living without the hassle of constant upkeep. But even the toughest materials need a little TLC now and then.

If you have ever stared at a stubborn stain on your Sunbrella lounge chair, wondering where to start, you’re in the right place. Today, I’m sharing my tried-and-true tips on how to clean Sunbrella fabric, drawing from personal trial-and-error and official guidelines to ensure your pieces stay vibrant and durable. Let’s dive in and make cleaning feel like a breeze.

Why Sunbrella Fabric Is Different

It’s important that you understand why Sunbrella differs from ordinary fabrics before diving into cleaning advice. Sunbrella uses solution-dyed acrylic fibers, as opposed to conventional materials that only have surface dye applied. This makes the fabric more resistant to fading and much more tolerant of deep cleaning because the color penetrates every fiber. One major benefit for homeowners is that they don’t have to worry about scrubbing off the color.

1. Routine Maintenance

The best way to keep your Sunbrella fabric looking its best is to stay ahead of dirt and debris. Think of it like brushing your teeth, regular care prevents bigger problems down the road.

• Brush off loose dirt: Use a soft-bristle brush or even a handheld vacuum to remove dust and pollen.

• Rinse occasionally: A light rinse with clean water once in a while helps prevent soil from settling deep into the fibers.

• Act quickly on spills: Just like with a carpet, the sooner you blot a spill, the less chance it has to stain.

Routine care only takes a few minutes but can save you from hours of scrubbing later.

2. General Cleaning Method

Mild soap and water usually work well for common dirt and mild stains, so you don’t need fancy chemicals. This is the easy procedure:

• Mix a cleaning solution of ¼ cup mild soap (like Dawn or Woolite) per gallon of lukewarm water.

• Apply the solution to the fabric using a sponge, a clean cloth, or a soft brush.

• Let it soak in for about 15 minutes. Don’t rush this step; it allows the soap to loosen the grime.

• Rinse thoroughly with a garden hose until no soap remains.

• Air-dry completely. Never use a dryer or iron, as heat can damage the fibers.

This method works for cushions, awnings, umbrellas, or any Sunbrella surface.

3. Tackling Stubborn Stains

Sometimes life throws tougher stains your way like wine, coffee, tree sap, or mildew. Fortunately, Sunbrella is engineered to handle these challenges.

For mildew or mold:

• Mix 1 cup bleach + ¼ cup mild soap per gallon of water.

• Apply the solution to the affected area and allow it to soak for 15 minutes.

• Gently scrub with a soft brush, then rinse thoroughly.

• Always let the fabric dry in the sun if possible, since sunlight naturally discourages mildew growth.

For oily spills (like sunscreen or grease):

• Apply cornstarch to absorb as much oil as possible.

• Scrape off the powder, then clean with the soap and water solution.

• Repeat if necessary until the stain lifts.

4. Machine Washing Option

Detachable cushion covers and other smaller Sunbrella items are machine washable. Make use of a delicate cycle, cold water, and a mild detergent. Unless the stain calls for it, stay away from fabric softeners and bleach. Never tumble dry; instead, let it air dry.

5. Protecting Your Fabric After Cleaning

Once your Sunbrella fabric is spotless, it’s smart to protect it so it stays that way longer. Sunbrella recommends reapplying a fabric guard like 303® Fabric Guard after deep cleaning. This restores the fabric’s after repellency, which gradually wears off with use and washing.

Extra Tips from Experience

• Don’t scrub aggressively, let the cleaning solution do the work.

• Always test cleaning products on a small, hidden area first.

• Avoid harsh detergents, chlorine (except in diluted solutions for mildew), or power washers, as they can shorten the fabric’s lifespan.

• If you live in a humid or rainy climate, store cushions indoors when not in use to prevent mildew buildup.

Final Thoughts

Sunbrella fabric is an investment in both style and durability, and with the right care, it will reward you with years of beauty. The key is consistency: brush off debris, rinse occasionally, and tackle stains promptly. Whether you’re dealing with a splash of red wine or a season’s worth of pollen, Sunbrella is tough enough to bounce back as long as you follow the proper cleaning methods.

Keeping your outdoor setup fresh doesn’t have to feel like a chore. With a little routine care and the occasional deep clean, your Sunbrella fabric can look almost as good as the day you bought it.
