Once Teak Wood is bleached by the elements, its original color can still be restored either by chemical application or by a light sanding.

Teak Cleaners are available from several sources (including Goldenteak). These cleaners are caustic, and restore the color by removing a fine layer of the wood and raising the grain slightly. If you use such a teak cleaner, please be sure to rinse the furniture thoroughly, until the residue stops foaming. This may take several rinses. After the rinsing, let the furniture dry thoroughly, and then apply the teak oil finish.

A Light Sanding of the bleached wood will remove the top bleached layer, and also restore the original color. Once again, you will need to apply the teak oil shortly after the sanding process to prevent further bleaching.
