The furniture you leave exposed to winter is the furniture you replace in spring. Freezing water expands in cracks, snow load warps frames, and months of moisture breed mildew on cushions. Winterizing your patio set each fall is a two-hour job that can add years to its life and save hundreds of dollars in premature replacements.
This guide walks through cleaning, protecting, covering, and storing your outdoor furniture the right way, with specific products that make each step easier. From a $24.39 protectant spray to heavy-duty 600D covers, you will find everything needed to lock your patio down before the first hard freeze.

Watch: How to Winterize Your Patio Furniture to Prevent Damage — Video Review
Start with a Deep Clean
Never cover dirty furniture; trapped grime and moisture cause the exact mildew and corrosion you are trying to prevent. Wash frames with mild soap and water, let everything dry completely, then treat surfaces with a protectant. STAR BRITE Outdoor Furniture Protectant Spray ($24.39, 4.5 stars from over 1,000 reviews) adds a UV and water-repellent barrier to metal, wood, and resin alike.
Protect Cushions Separately
Fabric cushions should never overwinter outdoors, even under a cover. Bring them inside a garage, basement, or deck box where they stay dry and rodent-free. If indoor space is tight, seal them in breathable storage bags rather than airtight plastic, which traps condensation.
Cover Everything That Stays Outside
For pieces too large to store, a quality waterproof cover is essential. The Vailge 600D Oxford chair covers ($44.99, 4.7 stars from more than 31,000 reviews) are a proven choice with air vents that prevent ballooning, while the GORILLA GRIP 3-seater sofa cover ($46.99) shields larger seating with heavy 600D fabric and UV coating.
Prevent Water and Snow Pooling
- Slip a support pillow like the SheeChung 47-inch inflatable airbag ($11.39) under covers so leaves, rain, and snow slide off instead of collecting.
- Angle table covers slightly so meltwater drains away from the surface.
- Check covers after storms to knock off accumulated snow before its weight strains seams.
Tips
- Choose covers with air vents to stop condensation and wind ballooning.
- Secure covers with built-in straps or windproof buckles so gusts cannot tear them off.
- Elevate furniture legs on blocks to keep them out of standing water and ice.
- Store hardware and small accessories in a labeled bin so reassembly is painless in spring.
Frequently Asked Questions
Do I really need to cover weatherproof furniture?
Yes; even rust-resistant metal and all-weather resin last longer when shielded from constant freeze-thaw cycles, UV, and pooling moisture.
Can I leave cushions outside under a cover?
It is not recommended; covers slow but do not stop moisture, so cushions still risk mildew and should be stored somewhere dry indoors.
What does 600D mean on a furniture cover?
The D stands for denier, a measure of fabric thickness; 600D indicates a heavy, durable weave that resists tearing and heavy weather far better than thin covers.
How do I stop covers from blowing away?
Use covers with integrated straps, drawstrings, or windproof buckles, and add a support airbag underneath so wind cannot get under the fabric as easily.
Conclusion
Winterizing comes down to four steps: clean and treat surfaces, store cushions indoors, cover what stays outside with vented 600D covers, and prevent pooling with a support airbag. Invest a couple of hours and a modest amount on quality protectants and covers this fall, and your patio set will emerge in spring looking exactly as good as the day you put it away.
