Outdoor furniture is built to handle the elements — but that doesn’t mean it won’t get dirty. Exposure to weather, birds, dust, and sun can leave your tables and chairs looking dull, stained, and tired. Left unchecked, this grime can damage the finish and shorten the furniture’s lifespan.
The good news? A simple cleaning routine can restore your furniture’s appearance and help it last for years. This ultimate guide walks you through how to clean every type of outdoor furniture — from natural wood to durable plastic and sleek metal.
Let’s get started.

Types of Outdoor Furniture
Before you break out the hose and scrub brush, it’s important to know what type of furniture you’re cleaning. Each material has its own care needs and cleaning methods.
Wood Furniture
Wood brings a warm, natural look to any outdoor space. Popular types include:
- Teak – Rich in natural oils, making it highly durable and weather-resistant
- Cedar – Lightweight, aromatic, and insect-repellent
- Pine – A softwood that’s beautiful but requires more maintenance
Wooden furniture adds timeless charm, but it does need regular upkeep. Sealing and oiling help prevent moisture damage and insect infestation — and keep it looking great season after season.
Metal Furniture
Metal furniture has a clean, modern style and is built to last. Common types include:
- Aluminium – Rust-resistant, lightweight, and easy to clean
- Wrought Iron – Heavy, traditional-looking, and ornate but prone to rust
- Stainless Steel/Cast Iron – Durable but may require special care to avoid discoloration
Metal is tough and weather-resistant, though aluminium may blow over in strong winds, and wrought iron needs to be sealed or painted to prevent rust.
Plastic Furniture
Plastic and resin furniture is a low-cost, low-maintenance option. Popular in backyards everywhere, these materials include:
- Polyethylene or Polypropylene – Lightweight and durable
- PVC or Resin – Great for stackable chairs and intricate designs
Plastic won’t rust and is easy to clean, but it can fade, crack, or become brittle over time if left exposed to UV rays.
Cleaning Tools You’ll Need
Having the right tools makes all the difference. Here’s what to gather before you begin.
Brushes and Sponges
- Soft-bristle brushes – Gentle on wood and plastic
- Stiff-bristle brushes – Great for removing stubborn grime
- Sponges – Ideal for smooth surfaces and gentle scrubbing
Soap and Detergents
- Mild soap or dish detergent – Versatile and safe for most materials
- Specialty cleaners – For teak, rust, or UV protection
Water Source
- Garden hose – Perfect for rinsing off large surfaces
- Bucket – Handy for spot cleaning or areas without hose access
Protective Gear
- Gloves – Keep your hands safe from harsh cleaners
- Masks – Useful when working with strong fumes or mildew
- Goggles – Recommended when using sprays or power tools
Cloths and Towels
- Microfiber cloths – Soft and absorbent for drying
- Cotton towels – For buffing or handling heavy-duty cleaning jobs
