What to Do With Patio Furniture When It Rains

When it starts raining, your first move depends on what you have outside. Cushions and fabric come in immediately. Metal furniture gets tilted or covered so water doesn't pool. Wood and resin can handle a normal shower just fine, but they need to be dried and wiped down within 24 to 48 hours to keep mold from taking hold. That's the core of it. Everything else in this guide is about doing those steps right so you're not dealing with rust, mildew, or warped wood a season from now.

Quick steps during a rain shower

You don't need to panic and haul everything inside every time clouds roll in. But you do need to act on the right things fast. Here's what I do the moment rain hits:

1. Grab the cushions first. This is non-negotiable. Seat cushions and back cushions are the most vulnerable thing on any patio, and even a short shower can soak the foam inside if the fabric isn't fully waterproofed. Bring them inside or stash them in a deck box.
2. Tilt or lean chairs against a wall or table. This stops water from pooling in seat wells and speeds up draining. A chair sitting flat with an inch of standing water in the seat is a mold problem waiting to happen.
3. If you have covers nearby, throw them on. A quick cover beats a full cleanup later. Just make sure the cover isn't going to create a giant water-trapping pocket — a poorly fitted cover with a saggy middle pools water just as badly as leaving the furniture uncovered.
4. Check for anything that can blow around. Lightweight plastic chairs, small side tables, and decor items can tip or skid in wind-driven rain. Cluster them together or move them against a wall to reduce the chance of dings and scratches.
5. Leave the umbrellas down. If you haven't already closed your patio umbrella, do it now. An open umbrella in rain and wind is asking for a broken rib or a toppled base.

The goal during the shower itself isn't perfection, it's damage control. You can do the real drying and cleaning once the rain stops.

Deciding what to protect vs what can stay out

Not all patio furniture is equally bothered by rain, and understanding which materials are vulnerable saves you a lot of unnecessary running around. Here's how the common materials actually hold up:

The big takeaway: cushions and anything iron or steel need your attention first. Natural wood and natural wicker come second. Aluminum and quality resin furniture are the most forgiving and can honestly stay out through normal rain with minimal fuss, as long as you wipe them down afterward.

It's also worth thinking about whether a hurricane or severe storm is coming rather than just a passing shower, the actions you'd take for that are a lot more drastic and involve securing or removing everything entirely. If a hurricane is in the forecast, you should plan for securing or moving patio furniture well before strong winds arrive hurricane or severe storm. For everyday rain, the table above is your guide.

How to dry patio furniture safely after it gets wet

Here's where most people fall short. They bring the cushions in, let the rain pass, and then just leave everything to air dry on its own. That works sometimes, but if it's humid out, or if water pooled in joints and crevices, you can still end up with mold within 24 to 48 hours. The EPA and CDC both flag that window as the mold-prevention deadline, and I've learned the hard way that humid summer days slow evaporation enough to make that deadline feel very tight.

Drying the frames (metal, wood, resin, wicker)

1. Move furniture into sunlight and airflow if possible. A breezy, sunny spot dries things dramatically faster than shade.
2. Wipe down all surfaces with a dry cloth or old towel. Don't skip the undersides, joints, and any hollow tubing — these hold water longer than flat surfaces.
3. For wood furniture, let it dry slowly and naturally after wiping. Avoid pointing a heat gun or hair dryer at it — rapid drying stresses the wood fibers and can cause cracking. The National Park Service's museum conservation guidance specifically cautions against fast-drying wet wood for exactly this reason.
4. Tilt or flip furniture to let water drain from hollow legs, tube frames, and seat channels.
5. Don't rush to re-seal or re-treat wood. Techniseal's product guidance says to wait at least 12 hours after rain before applying any sealer, and Teak Master recommends at least 3 hours of drying before applying weatherproofing products. Sealing damp wood traps moisture inside and speeds up the damage you were trying to prevent.

Drying cushions and fabric

Cushions are the highest-effort item to dry properly, and also the most important. The outer fabric might feel dry while the inner foam is still holding moisture. Here's how to handle them:

1. Stand cushions on their edges instead of laying them flat. This lets gravity help pull water down and out rather than keeping it pooled in the foam.
2. If the cushion cover is removable, unzip it and pull the foam insert partially out to increase airflow to the interior.
3. Set them somewhere with good airflow — a covered porch, garage with the door open, or indoors near a fan all work. Direct sun is great if the fabric can handle UV, but check the care label.
4. Lowe's outdoor fabric guidelines suggest allowing up to 48 hours for full drying after significant moisture exposure, and that tracks with my experience. If you squeeze a cushion corner and moisture comes out, it's not dry yet.
5. If you notice a musty smell or see any gray/white fuzz forming, treat it immediately — don't wait to see if it goes away. That's mildew starting and it spreads fast.

Seasonal storage options: covers vs indoor storage

Once you're past the immediate rain response, the bigger question is how you're handling protection long-term. There are two main strategies: furniture covers that let you leave pieces outside, and moving furniture fully indoors for the offseason or during bad weather stretches. Both work, but they work for different situations.

Furniture covers

Covers are the practical choice for most homeowners because hauling furniture in and out constantly isn't realistic. The key things to get right are fit, breathability, and pooling prevention. A cover that sags in the middle will collect water in that low spot, keeping moisture pressed against your furniture surface for hours or days. Coverstore and Resort Chairs both specifically call out pooling as a cause of rust, warping, and mold, not just an annoyance. A good cover fits snugly, has air vents or breathable fabric to prevent condensation buildup underneath, and ideally has a drawstring or tie-down to stay put in wind. Non-breathable covers trap humidity inside, which creates the exact conditions you're trying to prevent.

Whether a tarp works as a cover is a legitimate question if you're on a budget, but it comes with real tradeoffs around breathability and pooling. That's a topic worth digging into separately if you're considering it.

Indoor storage

For the offseason, or any time you're expecting extended rain or storms, moving furniture fully indoors is the best protection you can give it. A garage, shed, or basement works. The main thing people get wrong here is storing cushions in a damp space or stacking furniture without cleaning it first, you're just sealing mold in for the winter. Always clean and fully dry everything before it goes into storage, and make sure the storage area has reasonable airflow. If you're in a climate with cold winters, knowing when to bring your patio furniture inside and when it's safe to take it back out is its own separate calculation.

My honest recommendation: use covers for day-to-day rain protection during the season, and bring everything indoors once you're done using the patio for the year. That combination gives you convenience when you need it and real protection when it matters.

Cleaning and maintenance after rain

Once everything is dry, a quick post-rain cleanup prevents the slow damage that builds up over a season. You don't need to scrub everything after every shower, but after heavy rain, or if anything sat wet for more than a day, here's the routine I follow.

Basic post-rain cleaning for frames

1. Use a soft-bristled brush or cloth and a simple solution of mild dish soap or non-bleach liquid laundry detergent and warm water. Forever Patio's cleaning guide recommends this for resin, and it works well on most materials.
2. Scrub joints, welds, and crevices where dirt and moisture collect. These are the spots where mold and rust start.
3. Rinse thoroughly with a hose. Bob Vila specifically points out that leftover soap residue can trap moisture against metal surfaces and accelerate corrosion — so rinse, don't just wipe.
4. Dry with a rag or let air dry on a warm, breezy day. Don't skip this step for metal furniture.
5. Do not use a pressure washer. Forever Patio's guide calls this out explicitly — the force can damage finishes, force water into joints, and strip protective coatings.

Dealing with mold and mildew

If you spot mildew (gray or white fuzzy patches, or a musty smell), catch it early. For most surfaces, a 50/50 white vinegar and water solution works well, spray it on, wait 10 minutes, scrub with a soft brush, and rinse. Outdoor Living Inc. recommends this approach and it's gentle enough for wood, resin, and fabric. For tougher mildew on frames, a solution of one gallon of hot water and powdered oxygen bleach (as recommended by Home Depot's outdoor furniture care guide) handles more stubborn cases without the harshness of chlorine bleach. Always test any solution on a hidden spot first, some finishes react badly to even mild acids or bleaches. Avoid harsh chemicals and standard chlorine bleach on wood surfaces, as they can raise the grain and cause cracking over time.

Cleaning cushions after rain

1. Spray fabric with cold water first to loosen surface dirt.
2. Scrub with a soft brush and mild soap solution.
3. Rinse thoroughly — soap left in fabric holds moisture and smells.
4. Stand upright to drain and air dry completely before storing or replacing covers.
5. For mildew on fabric, the vinegar/water solution works, or a diluted oxygen bleach solution for more serious cases. Test first on the underside of a seam.

Long-term protection to prevent rust, mold, and fading

The goal is to stop having this same problem after every storm. These are the habits and one-time investments that make the biggest difference over a full season:

For metal furniture

Rust starts at chips, scratches, and bare metal spots. Touch up any damaged paint or coating with matching rust-inhibiting primer and paint before the season starts or as soon as you notice chips. Bob Vila explains that rust is a straightforward chemistry problem: iron, water, and oxygen make iron oxide. Remove the water and seal the bare metal, and you stop the reaction. Check welds and joints annually, these are the first places coatings fail.

For wood furniture

Wood is always going to gain and lose moisture, OSU Extension's research on wood-moisture relationships makes clear that this movement is unavoidable. What a good finish does is slow that process down and reduce the extremes. Re-seal or re-oil wood furniture once a year, ideally at the start of the outdoor season on a dry day with no rain in the forecast. Wait at least 12 hours after any rain before applying sealer. Keep an eye on the finish and if water stops beading and starts soaking in, it's time to re-apply.

For cushions and fabric

Spray cushion fabric with a water-repellent fabric protector (like 303 Fabric Guard or a similar outdoor fabric treatment) at the start of each season. This doesn't make them waterproof, but it dramatically slows absorption and gives you more time to act before moisture penetrates the foam. Store cushions in a deck box or bring them inside whenever rain is expected to last more than a few hours, that's the single biggest thing you can do to extend their life.

Cover management habits

If you use furniture covers, check them after every significant rain for pooled water. A pool of water sitting in a cover depression keeps moisture against the furniture surface for as long as it stays there, and that's enough time for rust or mold to start. Push the water off the cover, adjust the fit if it's consistently pooling in the same spot, and consider adding a support frame or cover prop underneath to create a tent shape that sheds water instead of collecting it. A properly fitted, breathable cover managed consistently does more for furniture longevity than any single cleaning product.

The bottom line on long-term protection is that it's mostly about consistency, not expensive products. Dry things within 48 hours, keep finishes maintained, store cushions out of the rain when you can, and catch rust or mold early when it's still easy to fix. Do that through a full season and your furniture will be in genuinely good shape when next spring rolls around.
