How to Clean Outdoor Cushions

How often you clean your outdoor cushions depends on how often they’re used, what your lifestyle is like, local weather conditions, and exposure to the elements or stains. A good rule of thumb is to give your outdoor cushions a good, deep clean twice a year and vacuum once a week to remove dirt and debris. Spot treat the occasional spills or stains as soon as possible. 

To maintain the look and longevity of your outdoor cushions, it’s a good idea to have the following on hand: 

• Vacuum with an upholstery attachment
• Soft-bristled brush
• Garden hose
• Mild detergent
• Bucket
• Clean towel
• High-quality upholstery cleaner
• High-quality outdoor fabric guard

• First, brush off any dirt or debris before it becomes embedded in the fabric.
• Spray on an upholstery cleaner or a cleaning solution of mild detergent and lukewarm water. 
• Dip a soft-bristled brush into the cleaning solution and scrub thoroughly. 
• Rinse thoroughly with clean water.
• Squeeze out any excess water and blot with a clean towel to soak up additional moisture. Allow the cushion to air dry completely. 
• For tougher stains, removable fabrics or cushion covers may be washed in the washing machine; do not machine dry. (Always check the cushion’s care instructions or the manufacturer’s website first.)

• Liquid spills: Blot (don't rub) with a clean, dry cloth as soon as possible. 
• Oil-based spill: Apply an absorbent such as corn starch. Wait 15 minutes and scrape away with a straight edge until the stain is gone. 
• Mold or mildew: Working outdoors, use a brush to scrape away as much of the mold or mildew as possible. Spray undiluted white vinegar over the stain and let set for at least 10 minutes. Scrub with a brush and repeat as needed. Soak a sponge or towel in a mixture of warm water and dish soap and clean the cushion. Rinse and let air dry completely. 

• Treat stains or spills as soon as possible. The sooner you treat a spill, the less likely a stain will set in. Make sure to wipe up any spills immediately. 
• Vacuum or brush cushions weekly. This will not only keep your cushions looking fresh and dirt-free, but it will also prevent staining and build-up. 
• Store or cover your cushions when not in use. A high-quality protective cover is a great way to extend the life of your outdoor cushions. Cover your furniture when not in use to protect from mold, mildew, and stains. Look for furniture covers that are breathable and mildew- and water-resistant. You can also consider storing your outdoor cushions, especially if you’re retiring them for the winter and know you won’t be using them for a few months. 
• Use a fabric guard spray. An outdoor fabric protector helps prevent stains, mildew formation, and fading from the sun.
