If left to age naturally, the surface of the teak will gradually change to a soft, silver-grey as the pigments in the surface layer of the wood start to fade away. If you would like your teak to age naturally, the only maintenance required is cleaning your furniture with mild soap and water or a teak cleaner once or twice per year. Clean the wood with a rag or sponge, and rinse thoroughly. To protect teak surfaces from staining and to help maintain the silver-grey patina on weathered teak, the use of a Teak Stain Protector is recommended.
To restore the teak wood to its original color, use a teak cleaner every 6-8 months. Allow the wood to dry thoroughly, then apply a teak sealant. Never use a metal bristle brush, pressure washer or steel wool for cleaning, as they will damage and discolor the surface.
In the case of a stain, first wash the area with warm soapy water. If the stain remains, use teak cleaner. The last resort is to sand lightly. Extremely stubborn stains will eventually be bleached out over time with exposure to sunlight.
