Cleaning and Power Washing Patio Furniture Without Damaging It
Your patio furniture is coated in pollen, grime, mildew, and weathering, and you want it cleaned without stripping finishes or shredding cushions and wicker.
Outdoor furniture collects dirt, pollen, and mildew, but the right cleaning method depends entirely on the material. Metal and solid resin can take a rinse and scrub, while teak, painted wood, wicker, and fabric cushions each need a gentler approach. Power washing is useful on sturdy frames but can strip finishes, gouge soft wood, or tear fabric if used carelessly, so the pressure and technique are matched to what's being cleaned.
How the job is done
- 1
Sort furniture by material
Pieces are grouped by what they're made of, since metal, resin, wood, wicker, and fabric each call for different cleaners and pressure to avoid damage.
- 2
Pre-rinse and remove loose debris
Cushions are removed and loose dirt, cobwebs, and leaves are rinsed or brushed off so cleaners can reach the actual grime.
- 3
Match cleaning method to the surface
Durable frames may be power washed at a controlled pressure, while soft wood, finishes, and wicker are hand-washed with a mild cleaner and soft brush to avoid harm.
- 4
Treat mildew and stains
Mildewed spots and stubborn stains are treated with an appropriate cleaner, allowed to dwell, and scrubbed gently so the spores and grime lift without scarring the material.
- 5
Rinse thoroughly and dry
All surfaces are rinsed clean of cleaner residue and allowed to dry fully, including cushions, so mildew doesn't return from trapped moisture.
What a pro checks
- Identifies each material first, since cleaning methods differ sharply
- Uses controlled pressure on durable frames and avoids it on soft wood
- Keeps a pressure washer well back from fabric and wicker to prevent tearing
- Treats mildew with an appropriate cleaner rather than just rinsing it
- Avoids harsh chemicals that can strip paint or finishes from wood
- Rinses off all cleaner residue so it doesn't leave streaks or attract dirt
- Dries cushions fully so trapped moisture doesn't grow mildew again

Frequently asked questions
Can I power wash all my patio furniture?
Not all of it. Sturdy metal and resin frames usually tolerate controlled pressure, but soft wood, painted finishes, wicker, and fabric can be gouged, stripped, or torn. Those are better hand-cleaned with a soft brush.
How do I get mildew off cushions?
Mildew is treated with a cleaner suited to the fabric, allowed to dwell, and gently scrubbed, then rinsed and dried completely. Drying fully matters, because leftover moisture is exactly what lets mildew grow back.
Will cleaning restore faded furniture?
Cleaning removes grime and mildew and brightens the surface, but it doesn't reverse sun fading or worn finishes. Faded wood or paint may need refinishing or a protective coating after it's clean and dry.
