What Is Sunbrella Fabric?

Outdoor furniture must be strong enough to withstand various weather conditions, so it’s usually made of tough material.

That’s why Sunbrella is a popular choice for homeowners! It’s a durable acrylic fabric that can handle various weather conditions.

It’s also long-lasting. You will have vibrant chairs and cushions that won’t fade quickly.

People usually use Sunbrella for shades, umbrellas, cushions, and upholstery. It’s an excellent investment for your outdoor furniture!


The Benefits Of Using Sunbrella Fabric On Cushions

Sunbrella is a recent innovation, but homeowners are going crazy for this durable fabric! Here’s why several people want this material for their outdoor furniture.


1. It doesn’t fade

Sunbrella fabric is solution-dyed, so every string is saturated with the dye. This method is the reason why its color won’t fade, whether it gets exposed to intense sun or rain.


2. It’s easy to clean

This material isn’t porous, so liquids will typically slide off or pearl at the top. Just a quick wipe will clean everything.


3. It’s durable

If you take good care of your Sunbrella material, it could last you up to 10 years.


Step-By-Step Process On Removing Mildew From Sunbrella Cushions

Luckily, cleaning your sunbrella cushion is similar to other fabrics. Here’s a guide on how to remove mildew from outdoor cushions.

Now, it’s time to clean your Sunbrella cushions!

You can make a soap and water solution in a spray bottle. Apply this to the stain and leave it for 15 minutes. 

You can also apply cornstarch to absorb excess oils. 


Step #2. Scrub the stain

Use a soft-bristled brush or a sponge, and gently scrub at the stain until it disappears. Reapply the solution as necessary for stubborn marks. 


Step #3. Create a bleach solution for the mildew

Put the bleach, water, and soap solution in a spray bottle. Apply on the patches with mildew and leave it on the fabric for 15 minutes.


Step #4. Scrub the mildew area

You can also use a soft bristle brush or sponge for mildew. Clean the entire cushion so you will remove all the spores. 


Step #5. Rinse your cushions

Run your fabric under the tap to remove all the bleach. 


Step #6. Leave your cushions to dry

You can use a sponge to absorb excess water. After that, let the Sunbrella air dry under direct sunlight.

How To Remove Other Dirt From Your Cushions

Besides stains and mildew, other things can dirty your Sunbrella cushions. Cleaning off grime and dirt is quick; it will only take you a few minutes!

You must prepare a soap and water mixture, similar to the one you use for stains. Put it in a basin and let the fabric soak in the liquid for 15 minutes.

Scrub the dirty spots, then rinse the cover with water. Leave the material to air dry with direct sunlight. 

These simple cleaning tips will keep your cushions in excellent shape!


How To Protect Your Fabric

Now that you’ve cleaned your material, you must prevent mildew and other dirt from forming. How should you do this? 

Just do what you would for other outdoor cushion fabrics. Here’s a guide on how to prevent mildew on outdoor cushions


Clean up spills right away

Sunbrella is waterproof, but leaving a stain to sit too long on the material will have negative effects; the fabric will absorb the stain and be a habitat for mildew.


Dab the liquid spills gently

Sunbrella isn’t porous so the liquid will sit on top of the fabric. Dab a cloth to absorb the excess water. 

You mustn’t rub the surface because it will push the liquid deeper into your fabric. Don’t forget to apply cornstarch if it’s an oily spill!


Do maintenance cleaning

Regular cleaning is the secret to keeping your home furniture and fabrics in good condition. Brush off loose dirt you see on your cushions and have a regular cleaning routine. 



Sunbrella is one of the best fabrics you can use for your outdoor cushions. It’s durable, stylish, and easy to clean. 

Sometimes, mildew can grow on your cushions when there’s constant exposure to moisture. You must do the proper steps to clean up the mildew and prevent it from growing back. 

You will make your backyard beautiful when you know how to clean sunbrella cushions with mildew. This troublesome fungus won’t be a match for your cleaning skills!
