So you have invested in Sunbrella cushions, powder coated aluminum frames, and all weather wicker. But how do you clean them when life happens? A spilled glass of red wine. Bird droppings on the sofa. Mildew spots after a humid summer.
Don't worry. Sunbrella fabric and outdoor furniture are easier to clean than most people think. The key is knowing the right method for each material and stain type. This guide walks you through everything from routine maintenance to stubborn stain removal.
Why Sunbrella Fabric Is Easier to Clean
Sunbrella is a solution dyed acrylic fabric. The colour is added before the fibre is created, not just coated on the surface. This means the pigment runs all the way through the material. When you clean it, the colour does not wash away or fade.
Most generic outdoor fabrics are piece dyed. The colour sits on the surface. This is why they fade quickly and why you cannot use bleach on them. With Sunbrella, you have more cleaning options, including diluted bleach for tough stains.
The fabric is also naturally hydrophobic. It repels water rather than absorbing it. Rain beads up and rolls off. Spills sit on the surface rather than soaking in. This gives you time to wipe them up before they set.
Routine Cleaning for Sunbrella Fabric
The best way to keep Sunbrella looking new is to clean it regularly before stains have a chance to set. A little maintenance goes a long way.
What you need:
- Soft bristle brush
- Mild dish soap (Dawn or Woolite work well)
- Garden hose
-
Clean cloths
The steps:
- Brush off loose dirt, leaves, and debris before they get embedded in the fabric.
- Mix a cleaning solution of 1/4 cup mild dish soap per gallon of lukewarm water.
- Spray or sponge the solution onto the fabric.
- Use a soft bristle brush to gently work the solution into the weave.
- Let the solution soak into the fabric for a few minutes.
- Rinse thoroughly with a garden hose until all soap residue is gone.
- Allow the fabric to air dry completely.
For an even easier solution, reach for Sunbrella Clean™ Multi‑Purpose Fabric Cleaner. This official Sunbrella product is specially formulated to safely break down everyday dirt, coffee, wine, and juice without leaving a sticky or cloudy residue. Just spray it on, blot with a clean cloth, and rinse. The soap‑and‑water method also works perfectly, but Sunbrella Clean is a convenient, brand‑approved option for quick spot cleaning.
Removing Common Stains from Sunbrella Fabric
Different stains require different treatments. Here is how to handle the most common ones.
Coffee, tea, soda, or wine: Mix 1 teaspoon of dishwashing liquid per 1 cup of water. Blot the stain, do not rub. Rinse thoroughly. For any remaining discoloration, a diluted bleach solution can be used.
Blood: Combine 1 teaspoon of dishwashing liquid and 1 teaspoon of hydrogen peroxide per 1 cup of water. Apply to the stain, then rinse.
Bird droppings, urine, or vomit: Mix 1 teaspoon of dishwashing liquid and 1 teaspoon of white vinegar per 1 cup of water. Clean the area and rinse completely.
Butter, grease, mayonnaise, sunscreen, or tomato sauce: For fresh stains, apply cornstarch as an absorbent. Let it sit for a few minutes, then remove the excess with a straight edge. Clean the remaining residue with 1 teaspoon of dishwashing liquid per 1 cup of water. For stubborn oil based stains, a strong degreaser may be needed.
Charcoal or soot: Vacuum to remove the excess. Treat with isopropyl alcohol, then clean with the dish soap solution.
Candle wax or chewing gum: Treat with isopropyl alcohol first. Then clean with the dish soap solution.
Removing Mildew and Mold from Sunbrella Fabric
Mildew is one of the most common problems with outdoor furniture, especially in humid climates like southern Ontario. The good news is that Sunbrella fabric itself does not promote mildew growth. However, mildew can grow on dirt, pollen, and other organic matter that collects on the surface.
This is why routine cleaning is so important. A quick rinse every month prevents dirt from building up and giving mildew a place to grow.
If you already have mildew stains, here is how to remove them.
What you need:
- 1 cup of bleach
- 1/4 cup mild dish soap
- 1 gallon of clean water
- Soft bristle brush
-
Spray bottle
The steps:
- Prepare a solution of 1 cup bleach and 1/4 cup mild soap per gallon of water.
- Spray or sponge the solution onto the affected area.
- Allow the solution to soak into the fabric for up to 15 minutes.
- Use a soft bristle brush to gently clean the area.
- Rinse thoroughly until all bleach and soap residue is removed.
- Air dry completely.
Do not let the bleach solution dry on the fabric. Always rinse it out completely. Also protect the area around your Sunbrella fabric when using bleach. It can discolor non Sunbrella materials like wood, concrete, or other fabrics.
A note on bleach: Some people worry about using bleach on fabric. With Sunbrella, it is safe. The solution dyed colour will not be damaged. But always rinse thoroughly and do not let the solution sit longer than 15 minutes.
For those who prefer not to use bleach, a white vinegar solution can be effective for mild mildew. Mix equal parts white vinegar and water. Spray onto the area, let sit for 15 minutes, scrub, and rinse.
Machine Washing Sunbrella Cushion Covers
Some Sunbrella cushion covers are removable and machine washable. Always check with the furniture manufacturer before removing the casing because cushion construction may vary.
If machine washing is approved:
- Close all zippers completely. This prevents snagging and damage.
- Machine wash in cold water on the delicate cycle.
- Use a normal amount of mild laundry detergent.
- For severe mildew, add 1 cup of bleach to the wash.
- Air dry only. Never put Sunbrella fabric in a dryer. High heat can shrink or damage the fabric.
This is a great option for a deep clean once a year. But for most spills and routine cleaning, spot cleaning or hand washing is sufficient.
How to Clean Different Patio Furniture Materials
Sunbrella cushions are only part of your patio setup. The frames, tables, and accessories also need regular care. Here is how to clean common outdoor furniture materials.
Aluminum and Powder Coated Frames
Aluminum is rust proof and lightweight. Powder coated finishes add extra protection and colour.
How to clean:
- Mix warm water with a few drops of mild dish soap.
- Use a non abrasive sponge or soft cloth.
- Wipe down all surfaces, paying attention to joints and crevices.
- Rinse thoroughly with a garden hose.
- Dry with a clean towel to prevent water spots.
For stubborn oxidation or chalky buildup: Add one tablespoon of white vinegar to the soap solution. Vinegar breaks down mineral deposits without harming the finish.
For extra protection: Apply a thin coat of automotive paste wax after cleaning. This adds UV resistance and makes future cleaning easier.
What to avoid: Do not use abrasive pads, scouring powders, acetone, or lacquer thinner. These can scratch or dull the powder coating.
Pressure washer safety: Aluminum can handle 1,200 to 1,500 PSI. But keep the nozzle at least 12 to 18 inches away. Use a 40 degree white nozzle, not a narrow pinpoint jet.
All Weather Wicker (Resin Wicker)
Resin wicker is made from polyethylene. It is designed to resist fading, cracking, and moisture. But dirt and pollen love to collect in the weave pattern.
How to clean:
- Use a vacuum with a brush attachment to remove loose debris from the weave.
- Mix mild soap with warm water.
- Use a soft bristle brush to scrub along the direction of the weave.
- For tight spots, an old toothbrush works well.
- Rinse from multiple angles to flush soap out of the gaps.
- Air dry completely.
For sticky residue or food spills: Let the soapy water sit on the stain for five minutes before scrubbing. This gives the soap time to break down the residue.
What to avoid: Do not use a pressure washer at close range. High pressure can loosen or crack the woven strands. If you must use a pressure washer, stay under 1,200 PSI and keep the nozzle at least 24 inches away. Spray along the direction of the weave, not against it.
Stainless Steel
Stainless steel resists rust, but it can develop tea staining or water spots over time.
How to clean:
- Rinse with fresh water weekly to remove salt, chlorine, and acidic residues.
- Wash with warm water and mild dish soap.
- Use a soft sponge or microfiber cloth.
- Rinse thoroughly and dry with a clean towel.
For oxidation or tea staining: Use a dedicated stainless steel cleaner. Follow the product instructions carefully.
What to avoid: Do not use steel wool or wire brushes. These can scratch the surface and actually promote rust. Also avoid harsh solvents.
Cushions and Fabric (Non Sunbrella)
If your cushions are not Sunbrella, the cleaning options are more limited.
Polyester cushions: Use only mild soap and water. Bleach will destroy the colour. Stubborn stains often remain.
General cleaning: Vacuum loose dirt. Mix mild soap with water. Apply with a soft sponge. Rinse well. Stand cushions on edge to drain and air dry. Never stack damp cushions flat because this traps moisture and invites mildew.
Winter Storage and Seasonal Care
Cleaning is only half the battle. Proper storage during winter is essential for keeping your furniture looking good year after year.
For Sunbrella cushions and pillows:
- Store indoors during winter. No fabric survives months of snow and freeze thaw cycles.
- Bring them inside or put them in a dry garage.
- Brush off debris before storing.
- Deep clean once per season with the bleach solution described above.
- For furniture frames and wicker:
- Use breathable, waterproof covers.
- Look for covers with cold crack technology. They stay flexible in freezing temperatures.
- Do not use plastic tarps. They trap moisture and cause mildew.
Generic covers from big box stores work fine for most furniture. Just measure your pieces and buy covers that fit snugly.
For all furniture:
- Do not leave standing water on any surface.
- In coastal or pool areas, rinse metal frames weekly with fresh water to remove salt and chlorine.
- Check for loose screws and bolts each spring. Tighten everything before the first warm weekend.
What to Avoid When Cleaning Patio Furniture
Some cleaning mistakes cause permanent damage. Here is what not to do.
Do not use abrasive tools. Steel wool, wire brushes, and scouring pads scratch surfaces. Once a powder coating is scratched, moisture can get underneath and cause bubbling or peeling.
Do not use harsh solvents. Acetone, lacquer thinner, and strong paint removers can dissolve powder coating and damage wicker.
Do not use bleach on generic fabrics. If your cushions are not Sunbrella or solution dyed polyester, bleach will ruin the colour. Stick to mild soap and water only.
Do not let cleaning solutions dry on furniture. Always rinse thoroughly. Dried soap residue attracts dirt and creates streaks.
Do not machine dry Sunbrella fabric. Heat can shrink or damage the fibers. Always air dry.
Do not store furniture damp. Moisture trapped under covers leads to mildew and rust. Let everything dry completely before covering or storing.
Frequently Asked Questions
How often should I clean Sunbrella fabric?
Rinse with clean water once a month to prevent dirt buildup. For a deeper clean, use mild soap and water every season or as needed. If you live in a humid area or under trees, clean more frequently.
Can I use vinegar on Sunbrella fabric?
Yes, white vinegar can be used for mild mildew or general cleaning. Mix equal parts vinegar and water. However, for stubborn mildew, the bleach solution is more effective.
Can I put Sunbrella cushions in the washing machine?
If the cover is removable and the manufacturer approves it, yes. Machine wash cold on delicate cycle with mild detergent. For mildew, add 1 cup of bleach. Always air dry. Never use a dryer.
How do I clean pollen off outdoor furniture?
Hose down the furniture to remove loose pollen. Then clean with mild soap and water using a soft brush. Pollen can stain if left too long, so clean it off within a few days.
Should I treat Sunbrella fabric with a protectant?
Sunbrella is engineered to repel water and resist stains without additional treatment. However, after repeated thorough cleanings or extended use, you may choose to refresh the fabric with a retreating agent like Sunbrella Restore. This is optional, not required.
Will bleach damage Sunbrella fabric?
No, when used correctly. The Sunbrella cleaning guide specifically recommends a diluted bleach solution for stubborn stains and mildew. Use 1 cup of bleach per gallon of water with 1/4 cup mild soap. Do not let it soak longer than 15 minutes. Rinse thoroughly.
Why does my Sunbrella fabric have mildew if it is mildew resistant?
Sunbrella fabric itself does not promote mildew growth. However, mildew can grow on dirt, pollen, food residue, and other organic matter that collects on the surface. Regular cleaning prevents this buildup.
Conclusion
Cleaning Sunbrella fabric and patio furniture does not have to be a chore. Most routine messes come out with mild soap and water. Stubborn stains and mildew require a diluted bleach solution. The key is to clean spills quickly, rinse thoroughly, and let everything air dry.
With proper care, your Sunbrella cushions will last five to ten years without fading or mildewing. Your aluminum frames will stay rust free. Your all weather wicker will look new season after season.
