How to Care for Patio Furniture: Cleaning and Seasonal Maintenance

The best way to care for patio furniture is to match your routine to the material, clean it at least twice a year (spring and fall), protect it with breathable covers between uses, and catch small problems like loose bolts and surface rust before they turn into expensive replacements. It sounds like a lot, but once you know what you have and what it needs, most of this takes less than an afternoon twice a year.

Start here: know what your furniture is made of

This is the step most people skip, and it's why they end up using the wrong cleaner and accidentally stripping a finish or cracking a frame. Before you grab a bucket and sponge, figure out what you're actually working with. The care rules for teak are completely different from the rules for aluminum, and the rules for natural wicker are almost the opposite of those for synthetic resin wicker.

Wood (teak, cedar, eucalyptus, acacia)

Teak is the gold standard for outdoor wood furniture because it's naturally dense and oily enough to resist moisture without any sealant or teak oil. Yes, skip the teak oil. It's actually a linseed-oil-and-solvent product that can go rancid, clog the pores of the wood, and eventually cause more problems than it prevents. Teak just needs an occasional light cleaning and that's genuinely it. Other hardwoods like eucalyptus and acacia need a little more attention, and softer woods like pine need annual sealing to survive outdoor seasons well.

Metal (aluminum, steel, wrought iron, cast iron)

Here's a quick test worth doing right now: hold a common refrigerator magnet up to your furniture frame. If it sticks, you have steel or iron. If it doesn't stick at all, you almost certainly have aluminum. This matters a lot because steel and iron rust, while aluminum only oxidizes (forming a dull white-gray haze rather than red flaking rust). Aluminum is far more forgiving outdoors, but it still needs regular cleaning and occasional oxidation treatment. Steel and iron frames need rust prevention built into their care routine.

Wicker and rattan

These two terms get mixed up constantly. Wicker is a weaving technique, not a material. Rattan is one of the natural materials that can be woven into wicker. The important distinction for outdoor care is whether you have natural wicker (rattan, bamboo, or similar organic materials) or synthetic/resin wicker. Natural wicker is genuinely fragile outdoors and should only be used in covered, sheltered spaces. It will crack, split, and deteriorate fast if left in rain or direct sun without protection. Synthetic wicker looks almost identical but is made from all-weather resin and handles outdoor conditions much better.

Plastic and resin

Resin and plastic furniture (think stacking chairs, Adirondacks, and most budget patio sets) is the most forgiving material to maintain. It doesn't rust, rot, or crack easily, but it does fade, get chalky from UV exposure, and collect surface grime in its texture. The main cleaning caution is to avoid anything abrasive or bleach-heavy that strips the surface.

Cushions and fabric

Outdoor cushions are usually filled with quick-dry polyester foam and covered in a solution-dyed acrylic fabric. Sunbrella is the most recognized brand in this category. These fabrics are designed to resist mold and fading, but they still need regular cleaning and re-waterproofing over time. The inner foam core is the real enemy here: if moisture gets in and doesn't get out, you'll have a mildew problem that no amount of surface scrubbing will fix.

Your cleaning schedule and how to actually do it

A twice-a-year deep clean (once in spring, once in late fall before storage) plus a quick wipe-down after storms or heavy use covers most of what outdoor furniture needs. Here's what a proper cleaning looks like for each material.

Wood furniture

1. Mix a few drops of mild dish soap into a bucket of warm water.
2. Wipe down all surfaces with a soft cloth or sponge, going with the wood grain.
3. For stubborn spots or algae buildup, a soft-bristle brush works well—nothing metal.
4. Rinse thoroughly with a garden hose at low pressure. Do not use a pressure washer on teak or other outdoor wood: it damages the wood surface and can drive moisture deep into grain.
5. Allow to air-dry completely before replacing cushions or covers.
6. If teak has developed surface stains or mildew marks, a diluted white vinegar solution (equal parts vinegar and water) applied and rinsed off handles most cases.

Aluminum furniture

1. Do this on a cloudy day or in the shade. Aluminum gets extremely hot in direct sun and the cleaning solution can dry and streak before you rinse it off.
2. Mix mild dish soap with warm water and wipe down all surfaces with a soft cloth.
3. For the dull, chalky oxidation haze that builds up over time, make a 1: 1 vinegar-water solution, wipe it over the affected areas, let it sit a few minutes, then scrub gently and rinse clean. A dedicated aluminum cleaner works faster on heavy oxidation.
4. Rinse well, especially at weld joints and underneath frame rails where soap tends to collect.
5. Dry with a clean cloth to prevent water spots.

Steel and iron furniture

1. Wash with mild soap and warm water using a soft cloth.
2. Check every joint, weld, and paint edge for rust spots while the surface is wet—they show up clearly.
3. Rinse and dry thoroughly right away. Leaving steel or iron wet accelerates rust.
4. Address any rust you find immediately (see the rust repair section below).

Wicker and rattan furniture

1. Use a soft damp cloth or very soft brush to wipe down all woven surfaces and the frame.
2. Never use abrasive cleaners, stiff brushes, bleach, or harsh solvents on wicker or rattan—these degrade the material and strip protective finishes.
3. Do not pressure wash. High pressure can break and unravel the weave.
4. For light dirt, warm water and a drop of mild dish soap on a soft cloth is enough.
5. Let the piece dry completely in a shaded, ventilated spot before covering or storing.

Plastic and resin furniture

1. Brush off loose debris first.
2. Mix non-bleach liquid laundry detergent or mild dish soap with warm water.
3. Scrub with a soft brush, working into textured surfaces where grime hides.
4. For mildew or sap spots, a product-specific mildew remover can be used; check that it's safe for resin.
5. Rinse well and air dry.

Stain removal quick guide

Seasonal care from spring to winter

Outdoor furniture lives through a full cycle of weather stress every year. Thinking about care seasonally (rather than only when something looks dirty) is the difference between furniture that lasts 5 years and furniture that lasts 20.

Spring: start-up inspection and deep clean

Spring is when you assess the winter's damage before it gets worse. Pull everything out of storage, remove covers, and go through this checklist before the first cookout of the year.

• Deep clean all frames using the material-appropriate method above.
• Inspect every weld, joint, and bolt for rust, cracking, or looseness.
• Check cushion covers for mildew, tears, or fading. Wash them now so they're fully dry before use.
• Look for UV damage on plastic and resin: chalking, cracking, or brittleness.
• Check wooden surfaces for raised grain, cracking, or discoloration—light sanding and re-oiling (for cedar/eucalyptus) may be needed.
• Test all hardware: tighten loose bolts, replace any that are corroded.
• Inspect covers for tears, broken tie-downs, or mold growth.

Summer: ongoing upkeep

Summer is mostly about staying ahead of small problems. A quick wipe-down after a thunderstorm, bringing cushions in when rain is forecast, and covering the set when you're not using it for several days makes a real difference over the season.

• Wipe down frames after storms or heavy pollen days.
• Bring cushions inside or stack them in a covered bin when rain is in the forecast.
• Apply a UV-protectant spray to plastic furniture in mid-summer if you notice chalking starting.
• Check for any new rust spots on metal frames and address them immediately.
• Keep furniture off wet ground where possible—set legs on rubber feet or small pavers to reduce moisture wicking.

Fall: prep for the cold months

Fall prep is honestly more important than spring start-up. Putting furniture away clean prevents mold, corrosion, and pest nesting over the winter. If you want to store patio furniture in a garage, make sure it is fully dry, covered with a breathable cover, and kept off wet concrete how to store patio furniture in garage. Don't just cover dirty furniture and hope for the best.

1. Do a second full deep clean of all frames and cushions.
2. Let everything dry completely before covering or storing. Covering damp furniture is how mildew starts.
3. Apply touch-up paint or rust-inhibiting primer to any exposed metal spots you found during the season.
4. For teak and other woods, do a final rinse and thorough drying, and make sure pieces aren't sitting in water puddles.
5. Store natural wicker indoors (garage, basement, shed) for the winter. It will not survive being left outside.
6. Fold and store cushions in a dry indoor space or a cushion storage bag. Don't leave them in a pile on a wet patio.
7. Cover remaining outdoor furniture with breathable, UV-resistant covers that have secure tie-downs.

Winter: storage and protection

The ideal for most patio furniture is indoor storage during winter, especially for natural wicker, wood, and cushions. If you're short on space, the next best option is quality covers and elevated storage so pieces aren't sitting directly on wet concrete or frozen ground. There's a lot more detail in this guide on winter storage, including how to protect different patio furniture materials outside best way to store patio furniture outside. There's a lot more to unpack on proper winter storage for specific furniture types and cushions, which is a full topic on its own. If you want the safest results, take those winter steps and then match them to your patio furniture material and cushion type winter storage for specific furniture types and cushions.

Protecting your furniture from weather and sun

Choosing the right cover

The single most important feature in a patio furniture cover is breathability. A thick, non-breathable plastic cover draped over your furniture for months traps condensation underneath and creates exactly the kind of damp, warm environment that mold and mildew love. Look for covers specifically labeled breathable, with UV treatment and reinforced tie-downs so wind doesn't constantly blow them off. After you choose breathable covers, make sure they are properly stored between uses to keep them clean and ready for the next season how to store patio furniture covers. Always clean both the furniture and the cover before storage: a cover coated in grime will transfer that grime right back onto your clean set.

Rust prevention for metal furniture

The best rust prevention for steel and iron frames is keeping the protective paint coating intact. Every chip, scratch, or worn spot is a spot where rust can start. After cleaning in spring and fall, touch up any bare metal immediately with a rust-inhibiting primer followed by a compatible topcoat. Products like Rust-Oleum's Stops Rust line are widely available and designed for exactly this use. Apply multiple thin coats rather than one heavy one, and let each coat dry fully.

Coatings, sealants, and oils: what actually helps

This is a heavily marketed category where a lot of products promise more than they deliver. A few honest notes: teak furniture does not need sealant, oil, or preservative. It genuinely maintains itself with just cleaning. Cedar and other outdoor woods benefit from annual application of a penetrating oil or wood sealer, but check the manufacturer's care guide first because some pre-treated woods shouldn't be sealed on top of their existing finish. Aluminum doesn't need any coating, but a coat of car wax or a dedicated aluminum protectant will slow down oxidation between cleanings. Metal frames with factory powder coating just need touch-up paint when the coating chips.

Hardware, frames, and joints: don't ignore the small stuff

Loose hardware is one of the most overlooked maintenance tasks for patio furniture, and it's also one of the fastest things to fix. Most outdoor furniture uses standard hex bolts or machine screws that you can tighten with a wrench or socket set in a few minutes. Do a systematic check every spring and fall: sit in each chair, rock it side to side, and wiggle each armrest. If something moves, tighten the hardware. If a bolt is corroded beyond turning, soak it with penetrating oil (like PB Blaster) for a few hours before trying again.

• Lubricate hinges, folding joints, and recline mechanisms with a silicone spray or light machine oil at the start of each season. This prevents squeaking and keeps joints from seizing.
• Check weld points on metal frames for cracks or corrosion. A cracked weld is a structural issue and may need professional welding or replacement.
• On wicker and rattan, look for sections of weave that have started to lift or unravel. A small dab of outdoor-safe adhesive can reattach minor sections, but avoid scrubbing or using abrasive cleaners around those areas since they'll damage the finish and lamination holding the material together.
• Rubber feet and nylon glides on chair legs wear down over time. Replacements are cheap (usually a few dollars at any hardware store) and prevent both scratching your patio and rust-starting moisture wicking from direct concrete contact.
• For wooden joints that have loosened, outdoor-rated wood glue applied and clamped overnight handles most cases. Make sure the joint is dry and free of old finish before applying.

Cushion and fabric care

Regular cleaning

For routine cleaning, brush off loose debris first, then spot-clean with mild soap and warm water using a soft brush. Rinse thoroughly and stand the cushions on their edges in a shaded, ventilated area to air dry completely before putting them back or storing them. This last step is where most people rush and cause their own mildew problems. Even a slightly damp cushion core left in an enclosed space will start to smell within a few days.

Mildew removal

For mildew on performance outdoor fabrics like Sunbrella, don't be timid with the treatment. Sunbrella's own guidance confirms that mold and mildew require a diluted bleach solution, not just mild soap. Mix a small amount of mild soap and a diluted amount of chlorine bleach in water, apply to the affected area, and let it soak for about 15 minutes before scrubbing gently with a soft brush and rinsing thoroughly. For severe mildew, the bleach concentration can be increased. Always rinse completely because leftover bleach residue will weaken the fabric over time. This approach applies specifically to solution-dyed acrylic fabrics designed for bleach tolerance. Check your fabric's care tag before using bleach on anything else.

Re-waterproofing

Outdoor fabric's water repellency degrades over time from UV exposure and repeated washing. If water is soaking in rather than beading off, it's time to re-treat. A fabric waterproofing spray like 303 Fabric Guard or similar products restores the DWR (durable water repellent) finish. Apply after cleaning and drying the fabric, let it cure fully, and you've bought another season of protection. Most outdoor cushions need re-waterproofing every one to two years depending on how much sun and rain they see.

Day-to-day fabric habits that matter

• Bring cushions inside or store them in a weather-resistant bin on rainy days when possible.
• Never stack wet cushions on top of each other. Moisture gets trapped between them.
• Let covers and cushion surfaces dry quickly after rain by standing them upright or propping them open.
• Store cushions indoors for the winter. A cushion storage bag or a large plastic storage bin in the garage works well and costs very little.

Troubleshooting common problems

Surface rust spots on metal frames

This is very DIY-able when it's caught early and the rust is localized. Here's the process: scrub off flaking rust with a wire brush or steel wool until you reach solid metal. Apply white vinegar directly to the area and let it sit for at least 30 minutes to dissolve remaining rust, then scrub again. Rinse and dry completely. Apply a rust-inhibiting primer in thin coats, let it dry fully, then apply a matching topcoat paint. Rust-Oleum's Stops Rust line is the go-to for this. The whole job takes a couple of hours and costs under $20 in materials. If rust is spread across most of the frame or has eaten through a structural section, that's a different conversation (see below).

Mildew on cushions

Surface mildew: bleach solution plus thorough rinsing, as described above. If the smell persists after cleaning and drying, the foam core is probably affected. You can unzip the cover and remove the foam insert, then wash the foam gently in a tub with soap and water, rinse thoroughly, and air dry it completely outside (this can take a full day or two). If the foam itself is deeply stained or structurally degraded, replacing just the foam insert is usually inexpensive and worth doing before buying an entirely new cushion.

Faded or chalky plastic furniture

Light chalking responds well to a thorough scrub plus a plastic restorer product (often sold as outdoor plastic furniture restorer or automotive plastic restorer). Apply with a soft cloth, buff in, and you'll recover a lot of the original color. Deep fading from years of UV exposure is harder to reverse, but a coat of spray paint designed for plastics can refresh the look for another few seasons. This is worth doing before spending money on replacement.

Squeaky or wobbly joints

Start with the simplest fix: tighten all the hardware. If the wobble is at a wooden joint rather than a bolt, clean out the joint and re-glue with outdoor wood glue. Squeaky metal hinges and pivot points just need lubrication. If a frame is structurally bent or a weld has cracked, that's either a trip to a local welder (often worth it for quality cast iron or wrought iron pieces) or a replacement decision.

Teak turning gray

Teak naturally weathers to a silver-gray color over time when left untreated outdoors. This is not damage, it's just oxidation of the surface wood. If you prefer the original honey-brown color, a light sanding with fine-grit sandpaper followed by cleaning will restore it. If you like the silver-gray look, you don't have to do anything at all. Either way, the wood is not deteriorating.

When to DIY and when to replace (or call for help)

The general rule I follow is this: if the structure is sound and the problem is surface-level (rust, fade, mildew, loose hardware), it's almost always worth the DIY fix. If the frame itself is cracked, bent, or has widespread corrosion eating through the metal, and the piece wasn't expensive to begin with, the math on replacement usually wins. For quality pieces you actually love, professional repair or refinishing is often worth every dollar.
