Hose down acacia furniture that is located near a pool or hot tub once weekly. Accumulated chlorine from treated pool water eats away at the furniture's weather-resistant finish over time.
Clean your furniture twice annually. Use a soap solution (1 tbsp. of liquid dish-washing detergent diluted in 1 quart of water is fine) and a scrub brush. Rinse twice and towel dry when you are done.
Wipe the furniture dry after rain, and wipe up any liquid that is spilled onto the furniture.
Place waterproof covers over your acacia furniture when it is not in use. Acacia wood is quite sensitive to moisture, even humidity in the air. When the furniture is moist, the wood cells expand and can cause the furniture to buckle and swell.
