Cleaning patio furniture the right way means matching the method to the material, starting with loose debris and mild soap, then rinsing and drying fully.
A dusty patio set covered in bird droppings after a storm isn’t hard to fix — but grab the wrong tool or cleaner, and you can scratch plastic, warp wood, or fade fabric. The core process is simple: remove loose dirt, wash with mild dish soap and water, rinse, and dry completely. What changes is the brush type and whether you can soak or must stay light. Material by material, here’s how to do it right.
The Basic Clean That Works for Every Material
The same foundation applies whether you’re working with teak, resin wicker, or aluminum: always start dry. Spray or brush off loose dust, pollen, and cobwebs before any water touches the surface. Mix a mild dish soap solution — the New York Times Wirecutter recommends about 1/4 cup liquid dishwashing soap in a bucket of warm water. Use a soft cloth, sponge, or soft-bristled brush. Scrub gently, rinse with a garden hose, and dry with towels or air before putting cushions back on or covering for storage.
Wood, Metal, Plastic, Wicker — What Changes Per Material
Each material tolerates different levels of moisture and abrasion. The table below gives you the quick reference for the most common patio furniture materials, with one rule holding across all of them: test any cleaner on a hidden spot first.
| Material | How to Clean | What to Avoid |
|---|---|---|
| Wood | Mild soap, soft brush, scrub with the grain | Soaking — excess moisture causes warping |
| Wicker / Rattan | Vacuum debris, soft brush for crevices | Soaking — water weakens woven fibers |
| Metal | Mild soap and water; dry immediately after rinsing | Leaving wet — that causes water spots and rust |
| Plastic / Resin | Mild dish soap and water; baking soda paste for stuck grime | Abrasive scouring pads — they scratch and hold dirt |
| Fabric cushions | Vacuum first, spot-treat with mild soap, rinse, air-dry flat | Prolonged soaking — can trap moisture and grow mildew |
For wood, excess moisture is the enemy; scrub with the grain and dry promptly. For wicker, a vacuum brush attachment is better than soaking. For metal, a quick dry with a towel after rinsing is the single step that prevents rust. For plastic, baking soda paste (a few tablespoons mixed with enough water to form a paste) lifts stubborn marks where soap alone won’t. For cushions, always check whether the cover unzips for machine washing before applying any liquid cleaner.
Spot Treating Stains and Mildew the Right Way
For bird droppings, tree sap, or mildew spots, you don’t need harsh chemicals. A white vinegar solution at 1 part vinegar to 1 part water works as a spot treatment; let it sit for 10–15 minutes before scrubbing and rinsing. Test vinegar on a hidden area first — it can affect certain fabric finishes, wood sealants, or metal coatings.

Drying: The Step Most People Skip
Drying is where mildew either survives or dies. After rinsing, use towels to blot cushions and frames, then let everything air-dry fully before covering or storing. Folding damp cushions into a storage bin practically guarantees a musty smell next season. Dry them in the shade instead and move them back to their spot the next day.
FAQs
Can I use bleach on patio furniture cushions?
Bleach can damage most outdoor fabric finishes and void warranties. Stick with mild dish soap or a vinegar solution for spot cleaning; if the care tag explicitly allows bleach, use only a diluted mix on a well-ventilated day.
How often should patio furniture be cleaned?
A full clean once at the start of the season and once before storing is enough for most climates. If your furniture sits under trees or near a dusty road, a quick rinse every few weeks prevents grime from building up into stains.
Do I need a pressure washer to clean patio furniture properly?
No. A garden hose and soft brush do the job without risk. Pressure washers can strip paint, dent aluminum, force water into wicker crevices, and fray cushion fabric if the nozzle is too close or the pressure too high.
