Outdoor furniture takes a beating year-round—from harsh sun and rain to dust, mold, bird droppings, and spilled food or drinks. Over time, even high-quality patio sets start to look dull, faded, and grimy. If you’ve been tempted to toss your weathered chairs or tables, stop! With a good power washing and a little care, you can bring most outdoor furniture back to life.
This article will walk you through how to safely and effectively power wash outdoor furniture made of plastic, wood, metal, or wicker—restoring both its appearance and its longevity.
💡 Why Power Washing Works for Outdoor Furniture
Outdoor furniture is often exposed to:
- UV rays that cause fading
- Dirt and grime buildup
- Bird droppings and insect residue
- Mildew and algae growth
- Stains from food, drinks, and grease
Power washing removes layers of embedded grime, brightens faded surfaces, and preps furniture for sealing or repainting if needed. It’s faster and more thorough than hand-scrubbing and can restore a “like new” look in minutes.
🧰 What You’ll Need
- Pressure washer (1,200–2,000 PSI)
- 25° or 40° spray tip
- Mild detergent or furniture-safe cleaner
- Soft brush or sponge
- Tarp or open space for drying
- Safety goggles and gloves 🧤🕶️
- Optional: wood oil, spray paint, or sealant for aftercare

🪑 What Types of Furniture Can Be Power Washed?
| Material | Can Be Power Washed? | Precautions |
|---|---|---|
| Plastic | ✅ Yes | Use wide spray, avoid high pressure |
| Wood (teak, cedar) | ✅ Yes | Use low pressure, allow drying before sealing |
| Metal (aluminum, steel) | ✅ Yes | Avoid flaking paint or rust spots |
| Wicker (resin) | ✅ Yes (synthetic only) | Use light spray only |
| Cushions/fabric | ❌ No | Remove before washing |
Never power wash natural wicker or rattan—they’re too delicate and can split under pressure.
🧽 Step-by-Step: Power Washing Outdoor Furniture
1. Prepare the Area
Move furniture to a flat surface—ideally over grass or a tarp to manage runoff. Remove:
- Cushions or pillows
- Umbrellas
- Rusty hardware (if replaceable)
Inspect for loose screws, cracked joints, or peeling paint.
2. Apply Cleaner
Spray furniture with a mild detergent or outdoor furniture cleaner. Let it sit for 5–10 minutes to break up dirt, mold, and oils.
💡 Avoid harsh chemicals like bleach or ammonia—they can damage paint, fabrics, and surrounding plants.
3. Choose the Right Nozzle and Pressure
- Use a 40° nozzle for delicate items or close surfaces
- Use a 25° nozzle for stubborn stains or wood grain
- Keep the wand at least 12–18 inches from the surface
- Spray at an angle to avoid gouging or lifting paint
Use sweeping motions to ensure even cleaning.
4. Spot Treat and Scrub if Needed
For stubborn spots:
- Use a soft brush to loosen mildew or baked-on grime
- Rinse and repeat if necessary
- Avoid wire brushes—they can scratch finishes
5. Rinse and Let Dry
Rinse each item thoroughly with clean water. Stand furniture upright and let it dry in the sun for several hours. Avoid stacking or storing while wet to prevent mildew.
✨ Post-Cleaning Restoration Tips
Once clean and dry, restore and protect your furniture:
- Plastic: Apply UV-protectant spray or polish to revive shine
- Wood: Sand lightly and apply wood oil or sealant
- Metal: Use rust-inhibiting spray or touch-up paint
- Synthetic wicker: Apply clear protectant to prevent future cracking
These steps help lock in your hard work and extend the life of your furniture.
❌ Common Mistakes to Avoid
- ❌ Using a 0° or 15° nozzle—too strong for most furniture
- ❌ Spraying too close—can strip paint or crack plastic
- ❌ Skipping pre-treatment—makes it harder to clean
- ❌ Washing cushions or fabric with high pressure
- ❌ Not rinsing thoroughly—leftover soap can cause fading or residue
🌿 Eco-Friendly Cleaning Options
- Mix 1 gallon water + 1/4 cup white vinegar for a natural mildew cleaner
- Use biodegradable soaps to reduce runoff impact
- Place furniture over grass or gravel to avoid chemicals entering drains
🧠 Bonus: How to Maintain Outdoor Furniture Long-Term
- Store furniture in a shed or under cover during winter
- Use waterproof covers during rainy seasons
- Re-oil wood once or twice per year
- Power wash twice a year or as needed
Proactive care can keep your patio furniture looking new for 5–10 years or more.
💬 Final Thoughts
You don’t have to live with dirty, faded, or neglected outdoor furniture. With a pressure washer and the right approach, you can restore most tables, chairs, and lounges in under an hour.
It’s a fast, satisfying weekend project that pays off every time you sit outside and enjoy your refreshed space 🪑🌞🧼. Don’t throw it away—spray it back to life!
