Fall Cushion Care: How to Clean and Store Your Porch Swing Cushions for Winter

As the afternoons cool off and porch season winds down, it's tempting to just toss a tarp over the swing and call it done for the year. But your cushions are usually the first thing to suffer over a long, damp winter. Fabric that goes into storage even slightly damp, or gets left outside through freeze-thaw cycles, tends to come back faded, musty, or spotted with mildew. A little care now saves you a cushion replacement come spring.

Here's a simple routine for cleaning and storing your porch swing cushions before the weather turns.

Start With a Real Cleaning, Not Just a Rinse

Before anything goes into a bin or a closet, give the cushions an actual cleaning. Vacuum both sides with an upholstery attachment to lift dust, pollen, and grit out of the seams, then check the manufacturer's care tag. Most performance fabrics, including Sunbrella-style porch swing cushions, can be spot-cleaned with a mild soap and water solution and a soft brush.

Work in small sections, rinse the soap out fully, and resist the urge to scrub hard on stubborn spots — repeated scrubbing can wear down the fabric's water-resistant coating faster than the stain itself would fade. For general grime across a whole cushion, a diluted vinegar-and-water mix works well as a final wipe-down and helps neutralize odors.

Dry Cushions Completely Before They Go Anywhere

This is the step people skip, and it's the one that causes the most damage. Any moisture trapped inside foam or fiber fill during storage turns into mildew within a few weeks, and once mildew sets into foam, it rarely comes back out.

Stand cushions on end in direct sun and let them air dry for a full day or two, flipping them periodically. If you're on a tight timeline, a fan pointed at the cushions speeds things up considerably. Press on the center of each cushion before packing it away — if you feel any coolness or dampness, it needs more drying time.

Choose Storage That Actually Breathes

Sealed plastic totes feel like the obvious choice, but they can trap residual humidity against the fabric all winter. A better option is a large canvas or breathable storage bag, kept somewhere dry like a garage shelf, basement, or covered shed — off the ground, away from direct contact with concrete, which can wick up moisture.

If your cushions are for a porch swing that stays outside year-round, at minimum bring the cushions and any accent pillows indoors, even if the frame itself is built to handle the elements. Fabric and foam are almost always the weak point in an otherwise weatherproof setup.

Protect Against Pests, Too

Rodents and insects look for exactly the kind of quiet, insulated spot a stored cushion provides. A few cedar blocks or sachets tucked into the storage bag help deter pests naturally without leaving a chemical smell behind. Avoid stacking heavy items on top of stored cushions — it compresses the fill and can leave permanent flat spots by spring.

A Quick Fall Cushion Checklist

Before you close up the porch for the season, run through this list:

Vacuum and spot-clean every cushion and pillow. Let everything dry completely in the sun or with airflow. Store in a breathable bag or box, off the ground, in a dry space. Add a natural pest deterrent like cedar. Note which cushions need re-covering next year while it's fresh in your mind.

If you find a cushion that's too far gone to save, it's worth browsing replacement porch swing cushions now rather than waiting until spring, when popular fabrics and sizes tend to sell out first. Either way, twenty minutes of cleaning and drying this fall means your swing is ready to sit in the moment the weather turns warm again.
