Iroko Care Guide
Everyday care for Iroko outdoor furniture: cleaning, protecting the finish and understanding how the timber naturally weathers over time.
The Character of Iroko
Iroko is a naturally durable African hardwood, recognised for its warm golden-brown tones and distinctive grain. Its strength and resistance to the elements make it well suited to outdoor living. At Block & Chisel, Iroko features in our Croxley and Plett Deck ranges, crafted in our Cape Town workshop. Each piece has its own natural character, with subtle variations in colour and grain that develop beautifully over time.
01
Everyday Care
- Remove dust, leaves and surface dirt regularly using a soft, dry cloth or gentle brush, working along the grain.
- Wipe spills promptly with a clean, absorbent cloth to prevent moisture and stains from settling into the timber.
- For general cleaning, use warm water and mild soap with a soft cloth or brush. Rinse gently with clean water and allow to dry thoroughly.
- Use placemats and coasters on dining tables, and lift decorative objects occasionally to prevent moisture collecting underneath.
02
Care by Finish
- Natural, untreated Iroko: Regular gentle cleaning is generally sufficient. The timber can be left to weather naturally, gradually developing a silver-grey appearance.
- Oiled finishes: To maintain the timber's warmer colour, a suitable exterior wood oil may be reapplied when required. Always confirm the existing finish and follow the product's application instructions.
- Sealed or painted finishes: Clean with a soft, damp cloth and mild soap. Avoid applying oils over sealed surfaces, and use a compatible product if the finish requires maintenance.
03
Natural Weathering
- Coastal areas: Rinse occasionally with fresh water to remove salt deposits, particularly on exposed outdoor furniture.
- Wet conditions: Avoid prolonged standing water and ensure good airflow around the furniture. Breathable covers can provide additional protection during extended periods of non-use.
- Direct sunlight: Expect gradual colour changes, particularly where some areas receive more sun than others. This variation is part of the timber's natural character.
Frequently Asked Questions
Not necessarily. Untreated Iroko can be left to develop its natural silver-grey patina. If you prefer a warmer finish, a suitable exterior wood treatment may help maintain its colour. Always check the existing finish before applying anything.
This is a natural result of exposure to sunlight and weather. The surface gradually changes from warm golden-brown to silver-grey. The colour change itself does not mean the timber is damaged.
Fine surface checks can occur as solid timber responds to changing moisture levels and temperatures. If a crack becomes large, affects a joint or raises structural concerns, contact us for advice.
- Pressure washers, stiff brushes and abrasive cleaners that can damage the wood surface.
- Harsh chemicals, bleach and strong detergents that may affect the timber or its finish.
- Allowing standing water, wet leaves or damp covers to remain against the furniture for extended periods.
- Applying oils, varnishes or sealers without first checking compatibility with the existing finish.
