How to Wash Outdoor Cushions

Understanding Your Outdoor Cushion Materials

Knowing what material your cushions are made of is the first step in cleaning them properly, and can prevent damage from harsh cleaners or improper care. If you’re not sure, check the tags or manufacturer info before you start.

If you’re still choosing outdoor cushions, consider water-resistant and UV-resistant fabrics like Sunbrella, polyester, acrylic, or Olefin, which can go a long way in keeping your setup weather and fade-resistant from the start. But even the best cushions will need some TLC every now and then. Most of these durable outdoor fabrics can be cleaned with warm water, dish soap, and a bit of vinegar to remove dirt, dust, and everyday stains.

Whether or not your cushions are removable also plays a part in the cleaning process. While removable cushions are by far the easiest to clean, there are cleaning methods you can use on attached cushions.

At Ash & Ember, our outdoor cushions are made with premium materials like water-resistant UV polyester canvas and Sunbrella fabric designed to weather the elements and withstand spills.

Pre-Cleaning Preparation

Cleaning your outdoor cushions properly is the best way to keep them looking bright and new year after year. Start with a few pre-steps prior to cleaning to remove surface debris, choose the right cleaning solution, and gather the tools you’ll need.

Wipe Off Dirt & Debris

Before you clean your cushions with any kind of cleaning solution, you should remove loose dirt and debris from the surface. You can use a vacuum with an upholstery attachment or simply shake your cushions out.

Prep Your Cleaning Solution

For a natural outdoor cushion cleaner, mix a ½ cup of dish soap,1 cup of white vinegar, and a gallon of warm water in a bucket. You can also use a mild laundry detergent. Some removable cushions and cushion covers are machine washable, but it’s best to handwash if you’re not sure. For cleaning tools, we recommend a soft brush and a hose.

Spot Test for Peace of Mind

We recommend testing an inconspicuous spot on your cushion to make sure the cleaning solution doesn’t cause damage or leave residue. Dab a bit of the cleaning solution on the underside of the cushion, then gently remove it with a damp cloth. Let it dry fully to make sure it doesn’t discolor the fabric or leave anything behind. If not, you’re good to go.

Washing Outdoor Cushions: Step by Step

The best way to clean outdoor cushions depends on whether or not your cushions are removable. Here’s how to care for them either way:

For Removable Cushion Covers

First things first—check the tag or manufacturer’s website to see if your patio cushions are machine washable. From there, follow the guidelines below based on the method they recommend.

• Machine washing: Most removable covers are machine washable. Always fully remove the cushion cover and zip it closed before washing. Opt for a milk, color-safe laundry detergent and wash on a gentle cycle, then air dry to maintain the shape of the cushion cover.
• Hand-washing: For handwashing outdoor cushion covers, a soap-and-vinegar solution works best for most stains. Use your soft brush to work the solution into the fabric, then gently rinse with a hose or in the sink. Finally, be sure to let the covers air dry thoroughly before putting them back on your cushions.

For Non-Removable Cushions:

Non-removable cushions can be a bit more challenging to clean, especially if they need a deep clean—but it’s not impossible. The best approach is to spot clean, though stubborn stains may require a more thorough treatment.

• Spot cleaning technique: Using a clean cloth or sponge, gently apply a small amount of a soap-and-vinegar solution or a specialized stain remover to the stained area. Blot or lightly rub the stain, then rinse the area with water to remove any remaining cleaning solution, then allow your cushions to air dry.
• Deep cleaning method: For tough stains, you may need a more aggressive approach. Pre-treating with a baking soda paste and letting it sit for 15-20 minutes can make a big difference. Stubborn stains may require multiple treatments to fully lift.

Tackling Common Stains & Issues

Cookouts, pool parties, and daily lounging—not all stains are the same, and each type calls for a different approach. Here are some tips for handling the more common types.

Mildew and Mold Removal

To remove mildew from outdoor cushions, try one of these methods:

• Vinegar solution: Because vinegar is a mild acid, it can be used to effectively treat mildew on outdoor cushions. Use pure white vinegar on the affected areas, Then gently rinse and allow to air dry.
• Bleach solution: Properly diluting the bleach solution is crucial in protecting your cushions, and even then it should only be a last resort when it comes to cleaning your outdoor cushions as it can permanently damage the fabric. However, if you’re dealing with mildew that won’t come off and will have to discard your cushions otherwise, it is an option. Mix one part bleach with four parts water to clean the mildewed areas.

Whichever method you use, we recommend spot testing an area on the underside of the cushion before applying the cleaning solution all over.

Mildew Prevention Tip: The best way to prevent mildew in the first place is to give them a thorough cleaning and storing them properly in a dry place when you’re not using them.

Food and Beverage Stains

Most food and beverage stains can be easily spot cleaned or treated by washing in the machine, but catching the spill early is key. If you spill a drink or notice a stain, dabbing at it with a cloth to soak up any liquid on the surface will prevent it from setting in.

If you spill wine or an oil-based food on your cushions, you may need more specific treatments:

• Oil stains: Apply cornstarch or baking soda to the stain as soon as possible, letting it sit for 10-15 minutes to absorb as much of the oil as possible—then gently scrape it off with a knife, spoon, or squeegee. You may need to repeat this step a couple of times. Finally, blot any remaining residue with a soap-and-vinegar solution before rinsing and letting it dry.
• Wine stains: Spilled wine happens—but it can set quickly, especially red. Acting fast is key. Blot the spill, then apply a soap-and-vinegar solution to soak the stain. Work it in with a soft brush or cloth, rinse with clean water, then let it air dry.

Tree Sap and Pollen

As much as we all love our trees and the shade they provide, tree sap and pollen can be a nuisance when it comes to keeping your patio furniture clean. Dry pollen can be brushed off the surface of your cushion, but pollen becomes much more stubborn when wet or damp.

If your removable cushion covers can be machine-washed, simply toss them in with a mild detergent. If not, clean the affected areas with a mixture of soap, water, and vinegar before rinsing and letting them air dry.

Tip: Resist the urge to scrub at tree sap. Scrubbing at the stains can push the sap deeper into the fabric and make it much more difficult to remove.

Sun Damage and Fading

If your patio cushions are left out in the sun, they’re vulnerable to sun fading. Unlike dirt and stains, once fading happens, you can’t reverse the effects. That means prevention is your best bet. Here are a few ways to prevent extensive sun damage:

• Use a protective coating: There are several UV-protective sprays on the market that can protect your cushions from prolonged sun exposure.
• Store your cushions properly: Always store your cushions out of the sun during the off-season.
• Invest in UV-resistant cushions: The best way to avoid sun fading is to opt for UV-resistant cushions to start with.

Ash & Ember uses UV-resistant polyester canvas or Sunbrella fabric for all of our outdoor cushions. That means they won’t fade or discolor in the sun, ensuring they look good as new year after year.
