Yes, teak oil can be used on outdoor wooden furniture, especially hardwoods like teak, acacia, or oak. It helps maintain the wood’s natural colour, protects against drying and cracking, and provides some water resistance.
Apply teak oil sparingly with a soft cloth, following the grain, and allow it to soak in before wiping off any excess. Regular application—usually once or twice a year—keeps furniture looking fresh and extends its lifespan. Avoid using teak oil on painted or stained wood, as it can interfere with the finish.
